Description

  The present invention relates to a translation system for translating an input character string.

  Conventionally, techniques for more accurate translation have been proposed. For example, Patent Document 1 discloses a technology in which a current position of a user is specified by a GPS (Global Positioning System) receiver, a translation dictionary of a facility corresponding to the specified position is selected, and translation is performed using the translation dictionary. Proposed.

JP 2009-258881 A

  However, even when the position is specified using the GPS receiver, there is a case where the translation dictionary cannot be selected properly. In the positioning method using the GPS, since a positioning error is large, for example, it is difficult to specify a specific store (for example, a pharmacy or a CD shop) in the department store even if it is possible to specify that the user is in a department store. is there.

  If the sentence to be translated is "I often come", if the location where the sentence is entered is a pharmacy, it is likely to show the efficacy of the drug, so it is preferable to translate it as "It's works well." . On the other hand, a CD shop is likely to indicate the frequency of listening, so it is desirable to translate it as "I listen a lot." However, it is difficult to specify which store is located at the position specified by the GPS as described above, and it is difficult to perform translation according to the store as described above.

  On the other hand, for example, if the user's position is specified using a beacon signal transmitted from a transmitting device provided at a specific position in the building (for example, near the store), the store where the sentence is input Can be specified. However, in this method, the position can be specified only at the position where the transmitting device is provided, and it is difficult to perform translation according to the position at an arbitrary position.

  The present invention has been made in view of the above problems, and has as its object to provide a translation system that appropriately performs translation according to the position of a user.

  In order to solve the above problems, a translation system of the present invention is a translation system for translating a character string in a source language into a character string in a target language, and a character acquisition unit for acquiring a character string in the source language. And position information that is information indicating a position measured by any of the plurality of positioning methods of the terminal device from which the character string obtained by the character obtaining unit is obtained, and information indicating the positioning method that has determined the position. And a storage unit that stores translation information for translating a character string in the source language into a character string in the target language in advance in association with the position and the positioning method. The translation information associated with the position and the positioning method indicated by the position information and the positioning method information acquired by the position acquisition unit are acquired from the storage unit, and the acquired Yo Comprising a translation unit for translating the acquired character string, and an output unit for outputting a result of the translation by the translation unit.

  According to the present invention, the translation system translates a character string using translation information corresponding to a position and a positioning method determined by the terminal device. When positioning is performed by a positioning method having high positioning accuracy, translation can be performed using translation information directly connected to the position of the terminal device. In addition, since the translation is performed using the translation information corresponding to any of the plurality of positioning methods, if the position of the terminal device can be located by any of the plurality of positioning methods, the translation is performed using the translation information corresponding to the positioning result. Can be. Thus, the translation can be appropriately performed according to the position of the user of the terminal device.

  According to the present invention, translation can be appropriately performed according to the position of the user.

  Hereinafter, embodiments of the translation system according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference symbols, without redundant description.

  FIG. 1 shows a translation system 1 according to the present embodiment. The translation system 1 is a system that translates a character string in a source language into a character string in a destination language (machine translation) and outputs a translated result (translated character string). That is, the translation system 1 is a system that provides a translation service. The translation system 1 converts the content of the voice input by the user into a character string, translates the character string, and displays or outputs the voice. In this embodiment, the source language is Japanese and the target language is English. The source language is not limited to Japanese, and may be another language different from the target language. The target language is not limited to English, and may be another language different from the source language. The translation system 1 includes a terminal device 10, a database server 20, and a translation server 30. For example, the terminal device 10 can transmit and receive information to and from the database server 20 and the translation server 30 via a mobile communication network or a communication network such as the Internet.

  The terminal device 10 corresponds to, for example, a smartphone, a mobile phone, or a PC (Personal Computer). Subsequently, details of the terminal device 10 will be described. The terminal device 10 includes an input unit 11, a positioning control unit 12 (positioning control unit), a beacon signal receiving unit 13 (positioning unit), and a Wi-Fi (Wireless Fidelity) signal receiving unit 14 (positioning unit, Wi-Fi). Is a registered trademark), a GPS signal receiving unit 15 (positioning unit), a translation model acquiring unit 16, a translation result acquiring unit 17, and a display unit 18.

  The input unit 11 is a part for inputting a voice uttered by the user of the terminal device 10. Specifically, the input unit 11 receives a user's voice input operation on the terminal device 10 and inputs a voice. The input unit 11 converts the voice into voice information by a known technique. The input unit 11 outputs the audio information to the translation result obtaining unit 17. In addition, the input unit 11 notifies the positioning control unit 12 that the voice has been input, triggered by the input of the voice.

  The positioning control unit 12 is a part that positions the position of the terminal device 10 by a plurality of positioning methods. The positioning control unit 12 uses one of a method of performing positioning by the beacon signal receiving unit 13, a method of performing positioning by the Wi-Fi signal receiving unit 14, and a method of performing positioning by the GPS signal receiving unit 15. 10 positions are measured. The positioning control unit 12 causes a plurality of positioning units to perform positioning in a predetermined order. As described above, the terminal device 10 has a plurality of positioning units that position the position of the terminal device 10 by a predetermined positioning method.

  Specifically, upon receiving the notification that the voice has been input from the input unit 11, the positioning control unit 12 first requests the beacon signal receiving unit 13 to search for a beacon ID. The beacon ID is information for identifying a device that transmits a beacon signal. When acquiring the beacon ID from the beacon signal receiving unit 13, the positioning control unit 12 generates, as the positioning method information, information indicating that the positioning has been performed using the beacon signal, and has performed the positioning using the beacon ID (position information) and the beacon signal. The translation information is output to the translation model acquisition unit 16. A device that transmits a beacon signal is installed at a specific position, and transmits a beacon signal in a narrow range (for example, a range of one store in a complex facility such as a department store) as compared with a positioning error by GPS. Therefore, the fact that the terminal device 10 has received the beacon signal indicates that the terminal device 10 is located near the device that transmits the beacon signal. Therefore, the beacon ID included in the beacon signal is information indicating the position of the terminal device 10.

  When the positioning control unit 12 obtains from the beacon signal receiving unit 13 information indicating that the beacon signal has not been received from the beacon signal receiving unit 13, the positioning control unit 12 subsequently transmits the access point ID to the Wi-Fi signal receiving unit 14. Make a search request. The access point ID is an identifier for identifying a Wi-Fi access point (Wi-Fi access point). When acquiring the access point ID from the Wi-Fi signal receiving unit 14, the positioning control unit 12 generates information indicating that positioning has been performed by Wi-Fi as positioning method information, and the access point ID (position information); The information indicating that the positioning is performed by Wi-Fi is output to the translation model acquisition unit 16. The Wi-Fi access point is installed at a specific position, and transmits a signal for Wi-Fi in a narrow range (for example, a range of one floor in a complex facility such as a department store) compared to a positioning error by GPS. I do. Therefore, the fact that the terminal device 10 has received the Wi-Fi signal indicates that the terminal device 10 is located near the device that transmits the Wi-Fi signal. Therefore, the access point ID included in the Wi-Fi signal is information indicating the position of the terminal device 10.

  When the positioning control unit 12 acquires from the Wi-Fi signal receiving unit 14 information indicating that the Wi-Fi signal has not been received from the Wi-Fi signal receiving unit 14, the positioning control unit 12 The GPS signal receiving unit 15 is requested to acquire the latitude and longitude. The positioning control unit 12 obtains the latitude and longitude from the GPS signal receiving unit 15, generates information indicating that positioning has been performed by GPS as positioning method information, and obtains the latitude and longitude (position information) and the latitude and longitude by GPS. Information indicating that the translation has been performed is output to the translation model acquisition unit 16.

  As described above, the positioning control unit 12 causes the respective positioning units to measure the position of the terminal device 10 in the order of the beacon signal receiving unit 13, the Wi-Fi signal receiving unit 14, and the GPS signal receiving unit 15. The positioning control unit 12 stores information indicating the order (order information) in advance, and causes each positioning unit to perform positioning based on the order information. This is based on the order in which the positioning errors of the respective positioning methods are assumed to be small. For example, when positioning is performed by the beacon signal receiving unit 13, the positioning error is within a certain range of a store, and when positioning is performed by the Wi-Fi signal receiving unit 14, the positioning error is within the same floor of a facility including a plurality of stores. It is assumed that when the positioning is performed by the GPS signal receiving unit 15, the positioning error is wider than when the positioning is performed by the beacon signal receiving unit 13 and the Wi-Fi signal receiving unit 14.

  The beacon signal receiving unit 13 is a unit that receives a beacon ID search request from the positioning control unit 12 and receives a beacon signal from a device that transmits a beacon signal. This beacon signal includes information indicating a beacon ID. The beacon signal receiving unit 13 acquires a beacon ID from the received beacon signal by known signal processing. Subsequently, the beacon signal receiving unit 13 outputs the obtained beacon ID to the positioning control unit 12 as a search result. If the beacon signal cannot be received, the beacon signal receiving unit 13 outputs information indicating the fact to the positioning control unit 12 as a search result. As described above, the beacon signal receiving unit 13 obtains the beacon ID serving as information indicating the position of the terminal device 10 from the beacon signal as described above, so that the beacon signal receiving unit 13 determines the position of the terminal device 10 I do.

  The Wi-Fi signal receiving unit 14 is a unit that receives a Wi-Fi signal from a short-range wireless communication device (Wi-Fi access point) when receiving a search request for an access point ID from the positioning control unit 12. Wi-Fi is a method for performing short-range wireless communication, and is a standard for a wireless LAN (Local Area Network). That is, the Wi-Fi signal receiving unit 14 receives a radio wave for short-range wireless communication. The Wi-Fi signal receiving unit 14 receives a Wi-Fi signal indicating an access point ID based on the received radio wave. The Wi-Fi signal receiving unit 14 acquires an access point ID from the received Wi-Fi signal by known signal processing. Subsequently, the Wi-Fi signal receiving unit 14 outputs the obtained access point ID to the positioning control unit 12 as a search result. When a Wi-Fi signal cannot be received, the Wi-Fi signal receiving unit 14 outputs information indicating that to the positioning control unit 12. As described above, the Wi-Fi signal receiving unit 14 acquires the access point ID serving as the information indicating the position of the terminal device 10 from the Wi-Fi signal as described above. Measures the position of the terminal device 10.

  The GPS signal receiving unit 15 is a part that receives a GPS signal from a GPS satellite when receiving a request to acquire latitude and longitude from the positioning control unit 12. The GPS signal receiving unit 15 performs a positioning operation based on a GPS signal received from a GPS satellite, and calculates the latitude and longitude of the terminal device 10 as position information. The GPS signal receiving unit 15 outputs the calculated latitude and longitude of the terminal device 10 to the positioning control unit 12. As described above, the GPS signal receiving unit 15 determines the position of the terminal device 10 by calculating the latitude and longitude serving as the information indicating the position of the terminal device 10 as described above.

  The translation model acquisition unit 16 is a part that acquires a translation model identifier corresponding to the position indicated by the position information and the positioning method indicated by the positioning method information. Here, the translation model (translation information) is information for translating a character string in the source language into a character string in the target language. The translation model identifier is information for identifying a translation model. When the translation model acquisition unit 16 acquires the position information (any one of the beacon ID, the access point ID, and the longitude and latitude) and the positioning method information from the positioning control unit 12, the translation model acquisition unit 16 sends the position information and the positioning method information to the database server 20. At the same time, it sends a translation model identifier acquisition request. When acquiring the translation model identifier from the database server 20, the translation model acquisition unit 16 outputs the translation model identifier to the translation result acquisition unit 17.

  The translation result acquisition unit 17 is a unit that acquires a translation result from the translation server 30. Specifically, first, the translation result acquisition unit 17 acquires speech information from the input unit 11 and acquires a translation model identifier from the translation model acquisition unit 16. The translation result acquisition unit 17 transmits the voice information and the translation model identifier to the translation server 30 and makes a translation request. When acquiring the translation result from the translation server 30, the translation result acquisition unit 17 outputs the translation result to the display unit 18. The display unit 18 is a part that outputs (displays) a translation result. The display unit 18 may be configured by a touch panel, and in that case, the display unit 18 may receive a user operation.

  Next, details of the database server 20 will be described. The database server 20 is a server device (a server having a database group for selecting a translation model) having a database in which the position indicated in the position information is associated with the translation model identifier. The database server 20 includes a search reception unit 21 (position acquisition unit), a translation model search unit 22 (translation unit), and a positioning-compatible translation model storage unit 23 (storage unit).

  The search receiving unit 21 is a part that receives a request for acquiring a translation model identifier. The search receiving unit 21 receives the position information and the positioning method information from the terminal device 10 and also receives a translation model identifier acquisition request. As described above, the search receiving unit 21 acquires the position information and the positioning method information. The search receiving unit 21 outputs the received position information and positioning method information to the translation model searching unit 22.

  The translation model search unit 22 is a part that searches, based on the position information and the positioning method information received from the terminal device 10, a translation model identifier corresponding to the position indicated by the position information and the positioning method indicated by the positioning method information. The translation model search unit 22 acquires the position information and the positioning method information from the search reception unit 21. Subsequently, the translation model search unit 22 searches for a translation model identifier based on the position indicated by the position information and the positioning method indicated by the positioning method information, with reference to the information stored in the positioning correspondence translation model storage unit 23.

  The positioning correspondence translation model storage unit 23 is a database that associates a position with a translation model identifier. More specifically, the positioning correspondence translation model storage unit 23 has a database in which a position is associated with a translation model identifier for each positioning method. FIG. 2 shows an example of information stored in the translation model storage unit 23 for positioning. FIG. 2A is a database showing a translation model corresponding to a beacon ID. The database shown in FIG. 2A previously stores “No”, “Beacon ID”, “Region”, “Building name”, “Store name”, and “Translation model” in association with each other. ing.

  “No” is the item number of the stored record. This item number is a unique value between records in the database shown in FIG. “Beacon ID” is information for identifying a beacon. “Region” indicates a region where the beacon is installed (for example, a prefecture name). “Building name” indicates the name of the building where the beacon is installed. "Store name" indicates the name of the store where the beacon is installed. “Translation model” indicates a translation model identifier (for example, the name of a translation model) suitable for the store where the beacon is installed. For example, when the terminal device 10 can acquire the beacon ID, the terminal device 10 is located near the beacon transmitting device corresponding to the beacon ID (that is, the store where the beacon transmitting device is installed). Therefore, the beacon ID is associated with a translation model suitable for the shop where the beacon is installed. As described above, the translation model identifier is associated with the position and the positioning method indicated by the position information and the positioning method information in the positioning correspondence translation model storage unit 23. The information stored in FIG. 2A only needs to have at least a “beacon ID” and a “translation model”.

  FIG. 2B is a database showing a translation model corresponding to an access point ID. The database shown in FIG. 2B corresponds to “No”, “Wi-Fi access point ID”, “region”, “building name”, “floor”, and “translation model” in advance. I remember it.

  “No” is the item number of the stored record. This item number is a unique value between records in the database shown in FIG. “Wi-Fi access point ID” is information (access point ID) for identifying a Wi-Fi access point. “Area” indicates an area (for example, a prefecture name) in which the access point is installed. “Building name” indicates the name of the building where the access point is installed. “Floor” indicates a floor on which the access point is installed. “Translation model” indicates a translation model identifier suitable for the floor where the access point is installed. For example, when the terminal device 10 can acquire the access point ID, the terminal device is located near the Wi-Fi access point corresponding to the access point ID (that is, on the floor where the Wi-Fi access point is installed). Since 10 is located, the access point ID is associated with a translation model suitable for the floor on which the Wi-Fi access point is installed. The information stored in FIG. 2B only needs to have at least “Wi-Fi access point ID” and “translation model”.

  FIG. 2C is a database showing translation models corresponding to latitude and longitude. The database shown in FIG. 2C stores “No”, “latitude and longitude”, “region”, “building name”, and “translation model” in advance in association with each other.

  “No” is the item number of the stored record. This item number is a unique value between records in the database shown in FIG. “Latitude and longitude” is the latitude and longitude indicating the position of the building described in the “building name”. The “region” indicates a region (for example, a prefecture name) of a place indicated by the latitude and longitude. "Building name" indicates a building name. “Translation model” indicates a translation model identifier suitable for the building indicated by the latitude and longitude. In the case where positioning is performed by GPS, a positioning error is large. Therefore, the latitude and longitude are associated with a translation model suitable for a building. The information stored in FIG. 2C only needs to have at least “latitude and longitude” and “translation model”.

  If the positioning method information obtained from the search receiving unit 21 is information indicating that positioning has been performed by using a beacon signal, the translation model searching unit 22 refers to the database shown in FIG. ID) of the record including the beacon ID corresponding to the ID. When the positioning method information acquired from the search accepting unit 21 is information indicating that positioning has been performed by Wi-Fi, the translation model search unit 22 refers to the database illustrated in FIG. The translation model identifier of the record including the access point ID corresponding to the information (access point ID) is searched. When the positioning method information obtained from the search receiving unit 21 is information indicating that positioning has been performed by GPS, the translation model search unit 22 refers to the database illustrated in FIG. (Latitude / longitude) is searched for a translation model identifier of a record including the latitude / longitude corresponding to the latitude / longitude. As described above, the translation model searching unit 22 obtains the translation model identifier associated with the position and the positioning method indicated by the position information indicated by the position information and the positioning method information obtained by the search receiving unit 21. .

  Subsequently, the translation model search unit 22 transmits the searched translation model identifier to the terminal device 10.

  Next, details of the translation server 30 will be described. The translation server 30 is a server that translates a character string (machine translation). The translation server 30 includes a translation receiving unit 31, a translation unit 32 (a character acquisition unit, a translation unit, and an output unit), and a translation model storage unit 33 (a storage unit).

  The translation receiving unit 31 is a part that receives a translation request from the terminal device 10. The translation receiving unit 31 receives the translation request while receiving the voice information and the translation model identifier from the terminal device 10. Translation accepting section 31 outputs the received voice information and translation model identifier to translating section 32.

  The translation unit 32 acquires the character string of the translation source language, and associates the translation model (the position and the positioning method indicated by the position information and the positioning method information) with the translation model identifier acquired from the translation receiving unit 31. (Translation model) from the translation model storage unit 33, and translates (machine-translates) the character string using the acquired translation model.

  The translation unit 32 acquires voice information and a translation model identifier from the terminal device 10 from which the character string is acquired via the translation reception unit 31. First, the translation unit 32 performs a speech recognition process on speech information to convert the speech information into a character string (text data). As described above, the translation unit 32 converts the voice information acquired from the terminal device 10 into a character string. The method of the voice recognition processing is not particularly limited, and various known methods may be used. Note that the translator 32 may execute the voice recognition process itself, or may transmit voice information to another device and convert the character string obtained by performing the voice recognition process to another device. May be received. For example, when the user of the terminal device 10 issues “I want a wooden child's footwear”, the translation unit 32 converts the above character string.

  The translation unit 32 translates the character string using a translation model corresponding to the translation model identifier. The translation unit 32 acquires from the translation model storage unit 33 a translation model corresponding to the translation model identifier acquired from the translation reception unit 31. The translation model storage unit 33 is a part that stores a translation model in association with a translation model identifier. This translation model is information for translating a character string in the source language into a character string in the target language. Specifically, a character string in the source language, a character string in the target language, and likelihood information indicating the degree to which the translation of the character string in the source language is a character string in the target language are associated with each other. Information. Note that the translation model storage unit 33 may store a translation model (normal model) not specialized to the position of the terminal device 10.

  As described above, the translation model storage unit 33 stores the translation model identifier and the translation model in advance in association with each other. Further, the translation model storage unit 23 stores the translation model identifier in association with the position and the positioning method indicated by the position information and the positioning method information. Therefore, the translation model storage unit 23 and the translation model storage unit 33 store the translation model in association with the position and the positioning method via the translation model identifier.

  Note that, even if the combination of the character string of the source language and the character string of the target language is the same, the likelihood is different for each translation model. For example, as the character strings of the translation target language for the character string of the translation source language "Hashi", there are "chopsticks", "edge", and "bridge". In the case of the miscellaneous goods model, the likelihood that the character string of the translation target language is “chopsticks” is “0.6”, and the likelihood that the character string of the translation target language is “edge” is “0.3”. It is assumed that the likelihood that the character string of the translation destination language is “bridge” is “0.1”. These likelihoods may be set in advance, or may be calculated based on past translation results when a translation request is made by the terminal device 10 located in the general store. Further, in the case of the normal model, the likelihood that the character string of the translation target language is “chopsticks” is “0.3”, and the likelihood that the character string of the translation target language is “edge” is “0.3”. , And the likelihood that the character string of the translation target language is “bridge” is “0.4”.

  When translating “chopsticks” by the normal model, the translator 32 translates “bridge” as “bridge” because the likelihood of “bridge” is the highest. On the other hand, when the translation model identifier indicates a miscellaneous goods model, the translation unit 32 gives priority to “chopsticks” because the likelihood that the character string of the translation target language is “chopsticks” is the highest. For example, when the position of the terminal device 10 indicates a general store (for example, a general store in a shopping district), the translation unit 32 performs translation using a general model. In this case, since the translation unit 32 translates using a translation model (a miscellaneous goods model) of a general store that may sell chopsticks, "hashi" is translated using the English word (chopsticks) of "chopsticks". Translate. This is for those who suppose to be "chopsticks" that are considered to be sold at a general store when the terminal device 10 is located near a general store when translating "chopsticks". However, this is because it is more natural than when it is assumed that the "bridge" has a small relationship with the general store. As described above, when the translation unit 32 acquires the character string “I want a wooden child's ladder,” the translation unit 32 acquires and translates the translation model according to the position. Translate "Iwant wooden chopsticks for children." The translation process itself is realized by a known translation method. As described above, by performing the translation using the translation model corresponding to the position and the positioning method of the terminal device 10, the translation unit 32 performs a natural translation (without feeling uncomfortable for the user).

  Further, the translation model may further include not only information in which a character string in the source language and a character string in the target language are associated with each other, but also information such as a translation rule used in a known translation technique. In this case, when the translation unit 32 acquires the character string “I often come”, if the location indicated by the location information acquired from the terminal device 10 is a pharmacy, it is highly likely that the translation indicates the efficacy of the drug. Is translated as "It's works well." Using a translation model having translation rules for pharmacies. Further, if the position indicated by the position information acquired from the terminal device 10 is a CD shop, based on the fact that there is a high possibility of indicating the listening frequency, using a translation model having a translation rule for a CD shop, “I listen a lot. " Further, the translation model associated with the position and the positioning method may not include information in which the character string of the source language and the character string of the target language are associated with each other. Any information may be used as long as the information can be translated into a character string. For example, information such as a translation rule used in a known translation technique may be used.

  The translation unit 32 transmits the translated result to the terminal device 10. As described above, the translation unit 32 outputs the translation result to the terminal device 10.

  Subsequently, FIG. 3 illustrates a hardware configuration of the terminal device 10 according to the present embodiment.

For example, the processor 201 may be implemented with at least one of these hardware. The above is the configuration of the translation system 1 according to the present embodiment.

  Next, a translation method that is an operation method of the translation system 1 according to the present embodiment will be described with reference to the sequence diagram of FIG. In the present process, first, the input unit 11 inputs a voice in response to a user operation, and converts the voice into voice information (step S1). The input unit 11 outputs the audio information to the translation result obtaining unit 17. Also, the input unit 11 notifies the positioning control unit 12 that a voice has been input. Subsequently, the positioning control unit 12 requests the beacon signal receiving unit 13 to search for a beacon ID. The beacon signal receiving unit 13 performs a beacon search in response to the beacon ID search request (step S2).

  The beacon signal receiving unit 13 outputs the search result to the positioning control unit 12. The positioning control unit 12 refers to the search result obtained from the beacon signal receiving unit 13 and outputs the beacon ID and the positioning method information to the translation model obtaining unit 16 when the beacon ID is obtained (step S3: YES). I do. On the other hand, when the beacon ID has not been acquired (when information indicating that the beacon signal has not been received from the beacon signal receiving unit 13) (step S3: NO), the positioning control unit 12 receives the Wi-Fi signal. A request is made to the unit 14 for an access point ID search.

  The Wi-Fi signal receiving unit 14 searches for an access point ID in response to the search request for the access point ID (step S4). The Wi-Fi signal receiving unit 14 outputs the search result to the positioning control unit 12. The positioning control unit 12 refers to the search result obtained from the Wi-Fi signal receiving unit 14, and if the access point ID has been obtained (step S5: YES), acquires the translation model from the access point ID and the positioning method information. Output to the unit 16. On the other hand, when the access point ID has not been acquired (when information indicating that a Wi-Fi signal has not been received from the Wi-Fi signal receiving unit 14 has been acquired) (step S5: NO), the positioning control unit 12 Requests the GPS signal receiving unit 15 to acquire the latitude and longitude. The GPS signal receiving unit 15 receives a GPS signal in response to the acquisition request of the latitude and longitude (Step S6).

  When receiving the GPS signal, the GPS signal receiving unit 15 calculates the latitude and longitude based on the GPS signal, and outputs the latitude and longitude to the positioning control unit 12. Upon acquiring the latitude and longitude from the GPS signal receiving unit 15, the positioning control unit 12 outputs the latitude and longitude and the positioning method information to the translation model acquiring unit 16.

  When the translation model obtaining unit 16 obtains the position information (any one of the beacon ID, the access point ID, and the latitude and longitude) and the positioning method information from the positioning control unit 12, the translation model obtaining unit 16 stores the position information and the positioning method information in a database. The request is transmitted to the server 20, and an acquisition request for the translation model identifier is made (step S7). The search receiving unit 21 of the database server 20 receives the position information and the positioning method information, and also receives a translation model identifier acquisition request (step S8).

  The search receiving unit 21 outputs the position information and the positioning method information to the translation model searching unit 22 in response to receiving the request for acquiring the translation model identifier. The translation model search unit 22 determines a database to be referenced from among the databases of the translation model storage unit for positioning 23 based on the positioning method information. Next, the translation model search unit 22 refers to the determined database and searches for a translation model identifier corresponding to the position indicated by the position information (Step S9). The translation model search unit 22 transmits the searched translation model identifier to the terminal device 10 (Step S10). In response, the translation model acquisition unit 16 of the terminal device 10 acquires a translation model identifier (Step S11). The translation model acquisition unit 16 outputs the acquired translation model identifier to the translation result acquisition unit 17.

  When the translation result acquisition unit 17 acquires the speech information from the input unit 11 and acquires the translation model identifier from the translation model acquisition unit 16, the translation result acquisition unit 17 transmits the speech information and the translation model identifier to the translation server 30, and transmits a translation request. (Step S12). The translation receiving unit 31 of the translation server 30 receives the voice information and the information indicating the translation model identifier, and also receives a translation request (step S13).

  The translation receiving unit 31 outputs the voice information and the translation model identifier to the translation unit 32 in response to receiving the translation request. The translation unit 32 recognizes the voice information by voice and converts the voice information into a character string. The translation unit 32 refers to the translation model storage unit 33 and acquires a translation model corresponding to the translation model identifier. The translation unit 32 translates a character string related to audio information using the acquired translation model (Step S14). The translation unit 32 transmits the translated result to the terminal device 10 (Step S15). The translation result acquisition unit 17 of the terminal device 10 acquires a translation result from the translation server 30 (Step S16). The translation result acquisition unit 17 transmits the acquired translation result to the display unit 18. The display unit 18 displays and outputs the translation result (step S17).

  As described above, the translation system 1 stores the translation model corresponding to the positioning method and the position in the positioning-compatible translation model storage unit 23 and the translation model storage unit 33 in advance, and stores the position and the position determined by the terminal device 10. The translation model identifier corresponding to the positioning method is specified by the database server 20. The translation server 30 acquires a character string based on the voice information input to the terminal device 10, acquires a translation model corresponding to the translation model identifier specified by the database server 20 from the translation model storage unit 33, and acquires the acquired translation. The above character string is translated using a model. The translation server 30 transmits the translated result to the terminal device 10, and the terminal device 10 displays the translated result.

  When positioning is performed by a positioning method with a high positioning accuracy (a positioning error is small) (for example, positioning by a beacon signal), the translation system 1 can perform translation using a translation model directly connected to the position of the terminal device 10. . Further, since the translation system 1 performs translation using a translation model corresponding to any of the plurality of positioning methods, if the position of the terminal device 10 can be located by any of the plurality of positioning methods, the translation model corresponding to the positioning result is obtained. Can be translated. The position of the terminal device 10 can be specified by the beacon ID or the access point ID only in a place where a device that transmits a beacon signal or a Wi-Fi signal is installed. Therefore, when the beacon ID or the access point ID cannot be obtained, positioning is performed using a GPS signal that can be received over a wide range, so that the position can be measured over a wide range. Therefore, the translation system 1 can appropriately perform translation at any place according to the position.

  Further, the translation model may include information that associates a character string in the source language with a character string in the target language. In this case, the character string in the target language corresponding to the character string in the source language can be changed depending on the position and the positioning method. That is, the character string in the target language corresponding to the character string in the source language can be appropriately translated according to the position and the positioning method. In the above-described embodiment, a case is described in which information in which a character string of a source language, a character string of a target language, and likelihood information are associated with each other is translated using a translation model associated with a position and a positioning method. Stated. Instead of associating likelihoods, information in which a character string in the source language is associated with a character string in the target language having the highest likelihood is translated using a translation model associated with the position and the positioning method. You may.

  The translation system 1 also includes a terminal device 10 capable of positioning a position. The terminal device 10 includes a plurality of positioning units for positioning the position of the terminal device 10 by a predetermined positioning method, and a positioning device in a predetermined order. A positioning control unit 12 that causes the unit to perform positioning may be provided. In this case, by determining the order of the positioning methods and performing positioning, the terminal device 10 can perform positioning with priority on a positioning method with high positioning accuracy.

  In the above-described embodiment, a case has been described in which a sentence that is the entire character string indicated by the input voice information is translated. Instead, a translation result obtained by dividing the character string for each word may be output. In the above embodiment, the case where the database server 20 and the translation server 30 are separated has been described. Instead, a server (integrated server) in which the database server 20 and the translation server 30 are integrated into one server may be used. In this case, the terminal device 10 transmits the voice information, the position information, and the positioning method information to the integrated server. The integrated server specifies a translation model using the position information and the positioning method information, and translates the character string obtained by converting the audio information using the specified translation model.

  In the above-described embodiment, the case has been described where positioning is performed by the beacon signal receiving unit 13, the Wi-Fi signal receiving unit 14, and the GPS signal receiving unit 15. Instead of this, positioning may be performed by a plurality of positioning methods other than the above combination. In the above-described embodiment, the case where the translation server 30 converts the audio information into the character string has been described. Instead, the terminal device 10 may convert the voice information into a character string. In the above-described embodiment, a case has been described in which a character string is obtained based on information input by voice. Instead, a character string input by a user operation may be obtained.

  In the above-described embodiment, the case has been described where the terminal device 10 performs the positioning after the voice information is input. Instead, the positioning may be continuously performed before the voice information is input. For example, the positioning control unit 12 appropriately acquires position information from any of the beacon signal receiving unit 13, the Wi-Fi signal receiving unit 14, and the GPS signal receiving unit 15, and stores the position information. When the voice information is input, the positioning control unit 12 outputs the latest position information and the positioning method information to the translation model acquisition unit 16.
