The navigation device 1 includes a map information storage unit 101, an output information storage unit 102, a current position information acquisition unit 103, an input reception unit 104, a route search unit 105, a travel situation information acquisition unit 106, a voice reception unit 107, and a voice recognition unit 108. The output unit 109 is provided.

  The map information storage unit 101 stores map information. Map information is information about a map. Moreover, the kind of map shown by map information, the data format of map information, etc. are not ask | required. The types of the maps are, for example, topographic maps, topographic maps, geological maps, land use maps, housing maps, route maps, road maps, guide maps, aerial photographs, satellite photographs, and the like. The data format is, for example, raster data, vector data, KIWI format, or the like.

  Moreover, map information usually has one or more point information. The point information is information regarding points on the map. Moreover, it can be said that point information is the information which shows the point on a map, for example. The point information has, for example, point attributes. An attribute is information in which an attribute name (hereinafter appropriately referred to as an attribute name) and an attribute value (hereinafter appropriately referred to as an attribute value) are associated with each other. It can also be said that the attribute value is information indicating the attribute. Moreover, the attribute of a point is usually one or more types.

  The attribute of a point is an identifier, a name, a position, etc., for example. Further, the location attribute may be, for example, an address, a telephone number, a FAX number, or a type. The type may be, for example, a so-called genre or a so-called category. Moreover, the said kind is not ask | required. The said type is an intersection, a station, a convenience store, a gas station, a restaurant, etc., for example.

  The map information usually has one or more road information. Road information is information about roads on a map. A road on a map is usually one or more sections (for example, a section from one intersection to another intersection) constituting a road from a starting point to an ending point. Moreover, it can be said that road information is the information which shows the road on a map, for example. The road information has, for example, road attributes. There are usually one or more types of road attributes.

  The attributes of the road are, for example, an identifier, name, type, speed limit, width, number of lanes, positions at both ends, names at both ends, scores, and the like. The type may be, for example, a type. Also, the type is a type based on, for example, an entity that has jurisdiction over the road, a moving body that can travel on the road, and the presence or absence of a fee required to travel on the road. That is, the types are, for example, a national road, a prefectural road, a prefectural road, a city road, a private road, a highway (automobile road), a general road, a toll road, and the like. Moreover, the name of both ends is the name of the point corresponding to both ends, for example. The said point is an intersection, for example. The score is usually a cost used for route search.

  Further, the map information may have one or more area information, for example. The area information is information related to the area on the map. The region on the map is, for example, a region, a region, or a district. Specifically, the areas on the map are, for example, prefectures, municipalities, and other administrative divisions. It can also be said that the area information is information indicating an area on the map. The region information has, for example, region attributes. The region attribute is usually one or more types.

  The region attributes include, for example, an identifier, a name, a type, a range, and the like. The type may be, for example, a type. The type is, for example, a type based on how the areas are divided. That is, the type is, for example, a region, a region, a prefecture, a municipality, or the like. The type may be, for example, the type of terrain. In this case, the type is, for example, a mountainous area, a plain area, a seaside, an urban area, or the like. The range is a set of three or more positions constituting the outline of the region.

  Hereinafter, the information indicating the position is appropriately referred to as position information. In the following, the position (position indicated by the position information) is usually a longitude and latitude. Further, the position may be coordinates on a map, for example. Further, the position may include, for example, a height (altitude).

  The output information storage unit 102 stores one or more output information. The output information is information output by the output unit 109 described later. Output refers to display on a display, projection using a projector, printing on a printer, sound output, transmission to an external device, storage on a recording medium, processing results to other processing devices or other programs, etc. It is a concept that includes delivery. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

  The output information may be anything as long as it is information unrelated to route guidance (information unrelated to route guidance). The output information is, for example, an image that is not related to route guidance, a voice that is not related to route guidance, a character string that is not related to route guidance, and the like. The image may include a so-called photograph, for example. The sound may include so-called music, for example. The output information is preferably information that can entertain, for example, a person (driver) who is driving a moving body in which the navigation device 1 is installed. In other words, the output information is preferably information with high entertainment properties, for example. Specifically, the output information is, for example, a character image unrelated to route guidance, a voice of the character, a character string corresponding to the voice (a character string obtained by converting the voice into a character string), and the like. More specifically, the output information is, for example, an image of a character asking the user about the current state, a sound asking about the current state, a character string corresponding to the sound, and the like. The output information may be so-called video, for example.

  The output information may be associated with an output condition, for example. The output condition is a condition for outputting associated output information. In this case, for example, one or more output conditions are associated with one output condition.

  Further, the output condition is a condition relating to, for example, a traveling situation, a current position, a current attribute, and the like. The traveling state is a traveling state of the moving body. Moreover, the driving | running | working condition may be anything if it is the present driving | running | working condition of the mobile body (for example, car) in which the navigation apparatus 1 is installed. The driving status includes, for example, speed, acceleration, ambient brightness, traffic congestion, time to reach the destination, estimated time of arrival at the destination, distance to the destination, driving status of the route (along the route Traveling to the destination, the route has been taken off), the time to the point where the route is changed (a point where guidance on the route is performed), the distance to the point where the route is changed, and the like. The traffic jam condition includes, for example, a traffic jam, a traffic jam not occurring, a traffic jam level (degree), and the like. Further, the distance to the destination is usually the distance of the route to the destination, but may be a linear distance to the destination.

  The current attribute is a map attribute corresponding to the current position. The map attributes are, for example, road attributes, point attributes, area attributes, and the like. That is, map attributes include, for example, a road name, a road type, a point name, a point type, an area name, and an area type. Further, it can be said that the map attribute corresponding to the current position is a result of applying the current position information to the map information, for example. The current position information is information indicating the current position. The application of the current position information to the map information means, for example, acquiring road attributes, point attributes, region attributes, and the like corresponding to the current position indicated by the current position information from the map information. In addition, the current attribute may be included in the driving situation, for example.

  From the above, it can also be said that the output condition is, for example, a condition relating to traveling state information, current position information, current attribute information, and the like. The travel status information is information indicating the travel status. The current attribute information is information indicating the current attribute.

  Specifically, the output conditions are, for example, that the current speed is greater than or equal to a predetermined threshold, that the current speed is less than or equal to a predetermined threshold, and that the current speed is predetermined. A time that is equal to or greater than a predetermined first threshold and equal to or less than a predetermined second threshold; a time that the current speed is equal to or less than a predetermined threshold; That the traffic is congested, that the time to the point where the route is to be changed is greater than or equal to a predetermined threshold, that the distance to the point where the route is to be changed is greater than or equal to a predetermined threshold, current position information The current position indicated by is a predetermined position, the name of the road indicated by the current attribute information is a predetermined road name, and the type of road indicated by the current attribute information is predetermined. The type of road, now The name of the point indicated by the sex information is the name of a predetermined point, the type of the point indicated by the current attribute information is the type of the predetermined point, and the name of the area indicated by the current attribute information is The name of the predetermined area, the type of the area indicated by the current attribute information is the predetermined type of the area, and the like. Further, the “above” may be “excess”, for example. The “below” may be “less than”, for example.

  Further, the output condition may be a condition relating to a character string, for example. The character string is, for example, a character string corresponding to a voice uttered by the user. In this case, the output condition is, for example, that the character string is a predetermined character string, or that the character string matches a predetermined character string pattern. The predetermined character string is, for example, a positive character string or a negative character string.

  Further, the output condition may be a combination of two or more of the above-described condition relating to the driving situation, the condition relating to the current position, the condition relating to the current attribute, and the condition relating to the character string. The combination is usually a logical product (AND), but may be a logical sum (OR). In addition, the output condition is preferably, for example, a condition having at least a condition related to a traveling situation. Further, when the output information is sound, it is preferable that the output information is associated with conditions regarding the current position and the current attribute, for example.

  The current position information acquisition unit 103 acquires current position information. Also, the current position information acquisition unit 103 normally acquires current position information automatically. Moreover, the timing which acquires present position information does not ask | require. The current position information acquisition unit 103 acquires the current position information, for example, periodically (every time a predetermined period elapses). In addition, the current position information acquisition unit 103 acquires the current position information, for example, every time there is an instruction from the user.

  The current position information acquisition unit 103 normally acquires current position information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a base station for mobile communication. In this case, the current position information acquisition unit 103 may have these devices or may be realized by these devices. The processing procedure of the current position information acquisition unit 103 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The input receiving unit 104 receives information and instructions. The information and instructions are usually information and instructions from the user. The information received by the input receiving unit 104 is, for example, destination information. The destination information is information indicating the destination. The structure of the destination information is usually the same as that of the point information. That is, the destination information includes, for example, information indicating the position of the destination, information indicating the name of the destination, information indicating the address of the destination, and the like.

  The instructions received by the input receiving unit 104 are, for example, a route search instruction, a power ON instruction, a power OFF instruction, and the like. The route search instruction is an instruction to search for a route to the destination. The reception of the route search instruction may be reception of destination information, for example.

  Note that acceptance means acquisition of information input from an input device such as a touch panel or a keyboard, reading of information stored in a recording medium such as an optical disk, magnetic disk, or semiconductor memory, or via a wired or wireless communication line. It is a concept that includes reception of information transmitted in the same manner.

  Further, the input means such as information and instructions in the input receiving unit 104 may be anything such as a menu screen or a keyboard. The input receiving unit 104 can be realized by control software for a menu screen, a device driver for input means such as a keyboard, and the like.

  The route search unit 105 searches for a route and acquires route information. A route is a route from a departure place to a destination. The departure place is usually the current position indicated by the current position information. The current position information is current position information acquired by the current position information acquisition unit 103. The destination is a point indicated by the destination information. The destination information is the destination information received by the input receiving unit 104. The route information is information indicating a route.

  The route information usually has two pieces of position information indicating the position of the start point (departure point) and the position of the end point (destination point). In addition to the two pieces of position information, the route information may include one or more pieces of position information indicating the position of the waypoint, for example. Further, the route information may be information composed of the two or more pieces of position information, for example. Further, the position and the position information may be a point and point information. The route information usually includes road information related to a road connecting two positions or two points. That is, the route information usually has an attribute of each road constituting the route. In addition, the road which comprises a path | route is normally 2 or more.

  Specifically, the route search unit 105 applies, for example, current position information and destination information to map information. The map information is map information stored in the map information storage unit 101. Further, “applying the current position information to the map information” means, for example, that the position on the map indicated by the current position information is set as the departure place. “Applying destination information to map information” means, for example, setting a point on the map indicated by the destination information as the destination. Then, the route search unit 105 searches for a route from the departure place to the destination. At this time, the route search unit 105 normally uses the score of the road information included in the map information as the cost of the route. At this time, the route search unit 105 normally searches for a route with the minimum score.

  Note that the route search usually uses a solution (algorithm) of the shortest route problem. “Solving the shortest path problem” is, for example, the Dijkstra method or the A * algorithm. In addition, since these solutions and methods and procedures for obtaining route information are well known, detailed description thereof will be omitted.

  The travel status information acquisition unit 106 acquires travel status information. In addition, the traveling state information acquisition unit 106 normally acquires traveling state information automatically. Moreover, the timing which acquires driving condition information does not ask | require. For example, the traveling state information acquisition unit 106 acquires the traveling state information periodically (every time a predetermined period elapses). In addition, the traveling state information acquisition unit 106 acquires traveling state information, for example, every time there is an instruction from the user.

  In addition, since the method, procedure, etc. which acquire driving condition information are well-known, detailed description is abbreviate | omitted. The traveling state information acquisition unit 106 includes, for example, a speed sensor and a speedometer, an acceleration sensor and an accelerometer, an illuminance sensor and an illuminometer, a beacon installed on a road, map information stored in the map information storage unit 101, Using the route information acquired by the route search unit 105, the current position information acquired by the current position information acquisition unit 103, and the like, the traveling state information is acquired. In this case, the traveling state information acquisition unit 106 may have these devices or may be realized by these devices. Further, the traveling state information acquisition unit 106 may be realized by an MPU, a memory, or the like. Further, the processing procedure of the traveling state information acquisition unit 106 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The voice reception unit 107 receives user voice. The user voice is a user voice. That is, the voice reception unit 107 receives a voice uttered by the user. In addition, the voice receiving unit 107 normally receives user voice via a microphone or the like. In this case, the voice reception unit 107 may have the device or may be realized by the device. The processing procedure of the voice receiving unit 107 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The voice recognition unit 108 recognizes user voice. Recognizing the user voice means converting the user voice into a character string and acquiring a character string corresponding to the user voice. For example, creating a character string includes creating a character string and converting it into a character string. In addition, for example, a so-called speech recognition technique is used for character string conversion. In addition, as a result of recognizing the user voice, the acquired character string is hereinafter referred to as voice recognition result information as appropriate.

  The output unit 109 outputs output information. The output information is output information stored in the output information storage unit 102. For example, when the output information is an image, the output unit 109 outputs the image on the screen, for example. For example, when the output information is sound, the output unit 109 outputs the sound, for example. For example, when the output information is a character string, the output unit 109 outputs the character string by voice, for example. To output a character string by voice is to output a voice corresponding to the character string. For example, when the output information is a character string, the output unit 109 outputs the character string on the screen, for example.

  Moreover, the output part 109 outputs output information according to traveling condition information, for example. The travel status is the travel status information acquired by the travel status information acquisition unit 106. In addition, outputting the output information in accordance with the traveling state information includes outputting the output information using predetermined traveling state information as a trigger, outputting the output information corresponding to the traveling state information, and the like. In this case, the output unit 109 outputs the output information by, for example, any one of the following methods (1) and (2), the procedure, and the like.

  (1) First, the output information storage unit 102 stores one or more pieces of output information not associated with output conditions. The output unit 109 holds, for example, one or more output conditions in advance. Then, the output unit 109 determines whether or not the traveling state information satisfies any one of the one or more output conditions. When any one of the one or more output conditions is satisfied, the output unit 109 acquires, for example, predetermined output information from the output information storage unit 102. Then, the output unit 109 outputs the acquired output information.

  (2) First, the output information storage unit 102 stores one or more output information associated with output conditions. Then, the output unit 109 determines which of the one or more output conditions the traveling state information satisfies. Then, the output unit 109 acquires from the output information storage unit 102 one or more output information associated with the output condition that the traveling state information satisfies. Then, the output unit 109 outputs the acquired output information.

  In (1) and (2) above, it is preferable that the output unit 109 outputs the output information, for example, when the traveling state information indicates that there is a traffic jam. In other words, this is a case where the travel status information indicates that there is a traffic jam and the output condition is that the travel status indicated by the travel status information is a traffic jam.

  Further, the output unit 109 may output output information corresponding to the current position information and current attribute information, for example. In this case, the output information storage unit 102 stores, for example, one or more pieces of information in which output information and output conditions are associated with each other on a one-to-one basis. The output information is preferably audio, for example. Then, the output unit 109 determines which of the one or more output conditions the traveling state information satisfies. Then, the output unit 109 acquires from the output information storage unit 102 one output information associated with one output condition that the traveling state information satisfies. Then, the output unit 109 outputs the acquired output information.

  Further, the output unit 109 may output output information corresponding to the speech recognition result information, for example. In this case, the output information storage unit 102 stores, for example, one or more pieces of information in which output information and output conditions are associated with each other on a one-to-one basis. The output condition is preferably a condition relating to a character string, for example. Then, the output unit 109 determines whether the speech recognition result information satisfies one of the one or more output conditions. Then, the output unit 109 acquires, from the output information storage unit 102, one output information associated with one output condition satisfied by the speech recognition result information. Then, the output unit 109 outputs the acquired output information.

  Further, the output unit 109 may output the output information according to any one or more of, for example, traveling status information, current position information, current attribute information, and voice recognition result information. In this case, for example, the output unit 109 outputs output information corresponding to an output condition satisfied by any one or more of the information.

  The output unit 109 normally outputs map information and route information. The map information is map information stored in the map information storage unit 101. The route information is the route information acquired by the route search unit 105. In this case, the output unit 109 normally outputs the map information and the route information so that the route indicated by the route information is indicated on the map indicated by the map information.

  Note that the output unit 109 may output, for example, output information corresponding to the time until the point where the course is changed. Further, the output unit 109 may output output information according to the time until the next route guidance, for example. That is, the output unit 109 may output output information associated with output time information indicating a time equal to or less than the time indicated by the driving status information or a time less than the time indicated by the driving status information. The route guidance is to output voices, images, characters, etc. relating to route guidance. The route guidance is performed by, for example, the output unit 109 or a route guidance unit (not shown). In addition, since the method of performing route guidance, a procedure, etc. are well-known, detailed description is abbreviate | omitted.

  The output information is associated with output time information, for example. The output time information is information indicating the time required for outputting the output information. Moreover, it can be said that the output time information is information indicating, for example, a period or length of outputting the output information. And the driving | running | working condition information acquisition part 106 acquires course change time information, for example. The course change time information is travel status information indicating the time to the point where the course is changed. Further, it can be said that the route change time information is, for example, information indicating a time from the present until the route guidance is performed. Then, the output unit 109 acquires output information associated with output time information indicating a time equal to or less than the time indicated by the course change time information. The “below” may be “less than”, for example. Then, the output unit 109 outputs during the time indicated by the acquired output information and the output time information associated with the output information.

  For example, the output unit 109 may output the output information when there is no passenger. In this case, a passenger presence / absence information acquisition unit (not shown) acquires passenger presence / absence information. Passenger presence / absence information is information indicating the presence or absence of a passenger. And the output part 109 acquires output information as mentioned above, when the said passenger presence information shows that there is no passenger. Then, the output unit 109 outputs the acquired output information.

  The passenger presence / absence information acquisition unit acquires the passenger presence / absence information using, for example, a weighted sensor installed in the seat, an in-vehicle camera, or the like. More specifically, the passenger presence / absence information acquisition unit acquires passenger presence / absence information indicating that there is no passenger when, for example, the value indicated by the weighted sensor installed in the seat is equal to or less than a threshold value. The passenger presence / absence information acquisition unit analyzes, for example, an image captured by the in-vehicle camera, detects the presence / absence of a person, and acquires passenger presence / absence information. In this case, the passenger presence / absence information acquisition unit may include, for example, a weight sensor, an in-vehicle camera, or the like, or may be realized by a weight sensor, an in-vehicle camera, or the like. The passenger presence / absence information acquisition unit may be realized by an MPU, a memory, or the like. The processing procedure of the passenger presence / absence information acquisition unit is usually realized by software, and the software is recorded in a recording medium such as a ROM.

  The output unit 109 may or may not include an output device such as a display or a speaker. The output unit 109 can be realized by driver software of an output device or driver software of an output device and an output device.

  The map information storage unit 101 and the output information storage unit 102 are preferably non-volatile recording media, but can also be realized by volatile recording media. Further, the process of storing predetermined information in the output information storage unit 102 or the like is not limited. For example, the predetermined information may be stored in the output information storage unit 102 or the like via a recording medium, a communication line, an input device, or the like.

  In addition, the route search unit 105 and the voice recognition unit 108 can be usually realized by an MPU, a memory, or the like. In addition, the processing procedure of the route search unit 105 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. Note that the route search unit 105 and the like may be realized by hardware (a dedicated circuit).

  Next, the overall operation of the navigation device 1 will be described using a flowchart. Note that the i-th information in the predetermined information is described as “information [i]”. FIG. 2 is a flowchart showing the overall operation of the navigation device 1.

  (Step S201) The navigation apparatus 1 determines whether or not the input receiving unit 104 has received a power-on instruction. If accepted, the process proceeds to step S202; otherwise, the process returns to step S201.

  (Step S202) The navigation device 1 starts a process of turning on the power.

  (Step S203) The current position information acquisition unit 103 starts acquiring current position information. Thereafter, the current position information acquisition unit 103 periodically acquires current position information until the power of the navigation device 1 is turned off.

  (Step S204) The traveling state information acquisition unit 106 starts acquiring the traveling state information. Thereafter, the traveling state information acquisition unit 106 periodically acquires the traveling state information until the navigation apparatus 1 is turned off.

  (Step S205) The output unit 109 starts acquiring current attribute information. Thereafter, each time the current position information acquisition unit 103 acquires the current position information, the output unit 109 acquires current attribute information using the current position information and the map information stored in the map information storage unit 101. To do. The acquisition of the current attribute information may be performed by, for example, a current attribute information acquisition unit (not shown). In addition, when the current attribute information is included in the travel status information, the current status information may be acquired by, for example, the travel status information acquisition unit 106.

  Note that the overall operation of the navigation device 1 described above is merely an example. That is, the overall operation of the navigation device 1 is not limited to the above description.

(Concrete example)
Next, a specific example of the operation of the navigation device 1 will be described. In this specific example, the navigation device 1 is assumed to be a car navigation system (hereinafter referred to as a car navigation system) installed in a car. In addition, the route search unit 105 uses the current position information acquired by the current position information acquisition unit 103, the destination information received by the input reception unit 104, and the map information stored in the map information storage unit 101 to search for a route. It has been searched (route information has been acquired). The route is, for example, FIG. In FIG. 4, an icon “S” is an icon indicating a departure place (current position). The “G” icon is an icon indicating a destination. In addition, it is assumed that the current position information acquisition unit 103 periodically acquires current position information, for example, for route guidance.

(Example 1)
In this example, an example will be described in which output information corresponding to the traveling state (traveling state information) is output. In this example, it is assumed that the output information storage unit 102 stores the output information shown in FIG. The output information (item name: image, sound, character string) is an image, sound, and character string, respectively, as the item name indicates. The image is a file name of the image, and a file identified by the file name is stored in the output information storage unit 102. The same applies to the voice. Also, the output information is associated with an ID for uniquely identifying the record and an output condition.

  First, it is assumed that the car is traveling according to the route displayed on the car navigation screen. Then, at a certain timing, it is assumed that the traveling state information acquisition unit 106 has acquired the traveling state information “congestion state: traffic jam” and “speed: 8 km / h”. The former traveling state information indicates that the road on which the vehicle is traveling is congested. The latter traveling state information indicates that the speed of the automobile is 8 km / h.

  Next, the output unit 109 satisfies the output condition “(congestion situation = congestion) & (5 km / h ≦ speed <10 km / h)” of “ID = 012” in FIG. to decide. The output condition means that the road on which the automobile is traveling is congested and the automobile speed is 5 km / h or more and less than 10 km / h. Then, the output unit 109 acquires the image “image101.png”, the voice “voice101-02.wav”, and the character string “How is the tone?” Which are the output information of “ID = 012” in FIG.

  Next, the output unit 109 arranges the acquired image and character string in a predetermined layout. Then, the output unit 109 outputs the arranged image and character string together with the acquired sound. An example of the output of the image and the character string is, for example, FIG.

(Example 2)
In this example, an example in which output information (voice) corresponding to the current attribute (current attribute information) is output will be described. In this example, it is assumed that the output information storage unit 102 stores the output information shown in FIG. The output information (item name: voice) is voice as the item name indicates. The sound is a file name of the sound, and a file identified by the file name is stored in the output information storage unit 102. Also, the output information is associated with an ID for uniquely identifying the record and an output condition.

  First, it is assumed that the car is traveling according to the route displayed on the car navigation screen. Then, at a certain timing, it is assumed that the output unit 109 acquires the current attribute information “prefecture name: XX prefecture” and “road type: prefectural road”. The former current attribute information indicates that the name of the prefecture corresponding to the current position is XX prefecture. The latter current attribute information indicates that the type of road corresponding to the current position is a prefectural road.

  Next, the output unit 109 determines that the two pieces of current attribute information satisfy the output condition “(prefecture name = XX prefecture) & (road type = prefectural road)” of “ID = 013” in FIG. . The output condition means that the name of the prefecture corresponding to the current position is XX prefecture, and the type of road corresponding to the current position is a prefectural road. Then, the output unit 109 acquires the voice “voice013.wav” that is the output information of “ID = 013” in FIG. Then, the output unit 109 outputs the sound.

(Example 3)
In this example, an example in which output information (voice) corresponding to user voice (voice recognition result information) is output will be described. In this example, it is assumed that the output information storage unit 102 stores the output information shown in FIG. The output information (item name: voice) is voice as the item name indicates. The sound is a file name of the sound, and a file identified by the file name is stored in the output information storage unit 102. Also, the output information is associated with an ID for uniquely identifying the record and an output condition.

  First, it is assumed that the car is traveling according to the route displayed on the car navigation screen. Then, at a certain timing, it is assumed that the user utters “I am tired”. Then, the voice reception unit 107 receives the user voice “I'm tired”. Then, the voice recognition unit 108 recognizes the user voice and acquires a character string “tired” which is voice recognition result information.

  Next, the output unit 109 determines that the above-described speech recognition result information satisfies the output condition “(user speech ⊃“ tired ”|“ sind ”” | “dull” ”of“ ID = 011 ”in FIG. To do. The output condition means that the user voice (voice recognition result information) includes one or more character strings of “tired”, “sniff”, and “dull”. Then, the output unit 109 acquires the voice “voice191.wav” of “ID = 011” in FIG. Then, the output unit 109 outputs the sound.

  In this specific example, an example will be described in which the output conditions are a condition related to a driving situation (driving condition information), a condition related to a current attribute (current attribute information), and a condition related to user voice (voice recognition result information). However, the output condition may be a combination of two or more of these conditions.
