Description

  The present invention digitizes the volume of received volume data received during a call and compares it with previously stored received volume reference level data so that the received volume level of the call is automatically appropriate for each call environment and for each speaker. The present invention relates to a telephone device that can be changed to a different value.

  There is a key telephone device that can change the reception volume based on prestored data in accordance with the state of the office telephone call or the extension telephone call state of each extension telephone. (For example, see Patent Document 1)

  In addition, when reproducing a received signal for each mode and for each call, the frequency characteristics are changed and set, and a mobile phone device that enables sound output with frequency characteristics corresponding to the communication environment and personal listening preference There is. (For example, see Patent Document 2)

However, in the apparatus described in Patent Document 1, since only the reception volume level is uniformly determined for each call state of the extension telephone and for each telephone, the volume level adjusted by each speaker for each speaker is adjusted. It cannot be changed. In addition, there is a drawback in that the level adjustment cannot be performed when the reception volume of the incoming call is attenuated due to the line state, and it remains attenuated.
In addition, since the device described in Patent Document 2 changes only on the basis of data stored in advance for each call, a predetermined volume is set unless the speaker performs an operation for changing the volume until the call ends. There was a drawback to remain.

Hereinafter, as an embodiment of the telephone apparatus of the present invention, a button telephone system comprising a main apparatus and a plurality of extension telephones will be described as an example with reference to the drawings.
FIG. 1 is a diagram showing the configuration of a button telephone system representing one embodiment of the present invention. This key telephone system accommodates external lines 11A to 11M and internal telephones 19A to 19N. The external lines 11A to 11M may be not only normal telephone lines but also IP (Internet Protocol) lines.

  1 is an external line interface unit 12 that is an interface of external lines 11A to 11M, an internal line interface unit 13 that is an interface of internal telephones 19A to 19N, and between an external line and an internal telephone. The exchange processing unit 14 for connecting the call path between the external lines or the extension telephones, the volume changing unit 15 for changing the call volume of the external line or the extension, and data for changing the reception volume for each speaker are accumulated. A speaker-specific reception volume adjustment processing unit 16, a speaker identification control unit 17 that identifies a speaker's transmission by voice recognition, and a main control unit 18 that controls these units.

  Each of the extension telephones 19A to 19N communicates with the interface unit 21 that transmits information via the extension interface unit 13 of the main apparatus 10 and the extensions 20A to 20N, the handset 24 of the extension telephone, and a loudspeaker (hereinafter referred to as a speaker) 25. The call processing unit 22 for connecting the route, each unit of the extension telephone, the terminal control unit 23 for storing and controlling various data, and the volume of the voice from the other party to be played back by the handset 24 or the speaker 25 ( The volume button 27 is used to adjust the increase / decrease of the reception volume. The extensions 20A to 20N may be not only normal telephone lines but also IP (Internet Protocol) lines.

Hereinafter, a means for a specific speaker A to adjust the reception volume using the extension telephone 19A will be described. When the speaker A operates the volume button 27 of the extension telephone 19A during a call with an outside line or extension partner, the terminal control unit 23 of the extension telephone 19A transmits a command requesting increase / decrease of the volume to the main apparatus 10. Then, main apparatus 10 adjusts volume changing unit 15 according to the command, changes the volume of the audio signal from the other party, and sends it to extension 20A.
Note that each time the volume button 27 is adjusted, data relating to the adjusted reception volume is accumulated as reference level data in the reception volume adjustment processing unit 16 for each speaker of the main device 10. Instead, even if the volume of the other party's voice input to the main device 10 changes, the reception volume sent to the extension telephone is automatically controlled so as to have the volume adjusted earlier.

The speaker-by-speaker reception volume adjustment processing unit 16 in the main apparatus 10 samples the output voice by removing the silent part from the volume change unit 15 and digitizes the volume level (for example, an average volume value of 1 minute or more). . Then, the signal level of the voice signal is automatically adjusted so as to match or approximate the average signal level indicated by the reference data of the speaker A stored in the speaker-specific adjustment processing unit 16.
Here, when the volume button 27 of the extension telephone 19 is operated, the digitized volume level of the output voice from the volume changing unit 15 adjusted by the operation is registered as the reference level data of the speaker. .

Next, means for adjusting the reception volume for each call environment will be described with reference to FIGS.
FIG. 2 is a table example of reference data stored in the reception volume adjustment processing unit 16 for each speaker.
In this example, the received volume reference level data is stored in the memory (a00, b00,... ZNN) of each speaker (A, B, C,... Z) for each speaker use environment. . The speaker use environment is composed of a line classification, an ID, and a telephone function. The line classification is an extension and an external line, and ID is an extension number of an extension telephone (19A, 19B,..., 19N) that can be used by the speaker. (10, 11,..., 23), and when a speaker makes an incoming call from an outside location to the external line of the button telephone system and transfers it to another external line of the system (hereinafter referred to as a transfer telephone), the incoming external line is recognized. It is assumed that there are a plurality of person numbers (1111111, 222222222,..., Nnnnnnnn).
These line and ID classifications are mainly for adjusting the received sound volume level based on the difference between the ambient noise of the speaker and the voice transmission loss.
In the case of speaker reception, for example, there is a difference in the influence that the speaker receives from the surrounding environment, such as the size of the speaker's desk and ambient noise. “Normal” and “hands-free” calls with speaker reception are held individually.
The received sound volume reference level data is initially stored in advance as received sound volume level data.

  FIG. 3 is a flowchart showing the main operation of the present invention. When a certain call environment is generated in the button telephone system, the main control unit 18 of the main apparatus 10 analyzes the call environment in step S11. When a speaker (for example, speaker A) uses an extension telephone (for example, 19A) and a call with an outside line (for example, 11A) is generated using the handset 24, “normal state”, speaker (for example, speaker B) When an incoming call with an ID (for example, caller number 1111111) is made from an outside location to an external line (for example, 11B), and a call with another external line (for example, 11A) is generated using the handset via the external line interface unit 12, "Transfer" “Phone state”, when a speaker (for example, speaker A) uses an extension telephone (for example, 19A) and a call with an external line (for example, 11A) is generated using speaker 25 and microphone 26, “hands-free state” Classify each.

  At the same time, the main control unit 18 of the main apparatus 10 recognizes the speaker ID in step S11. In the case of this example, the ID in the “normal state” and “hands-free state” is the extension number 10 of the extension telephone 19A used by the speaker A received from the extension interface unit 13, and the “forwarding phone state” The ID at the time is the caller number 111111 of the telephone used by the speaker B who is received from the outside line interface unit 12, and the ID at the "normal state" and "hands free state" is the extension interface unit 13 The extension number 10 of the extension telephone 19A used by the speaker A who receives the call.

In the normal state or the hands-free state, in step S12, the main control unit 18 identifies the speaker's transmission signal received from the extension interface unit 13 by the voice recognition function of the speaker identification control unit 17, and specifies the speaker. (Speaker A in this example). Further, in the case of the transfer telephone state, the speaker identification control unit 17 identifies the speaker's transmission signal received from the incoming call outside line 11B via the external line interface unit 12, and the speaker is specified.
Thereafter, in step S13, the main control unit 18 samples the received voice data of the other party from the outside line 11A via the outside line interface unit 12 and the exchange processing unit 14 by removing the silent part by the volume changing unit 15, and the volume. Digitize levels.
In the following, the volume change control for each speaker is performed in a pattern corresponding to each call environment.
In the speech recognition, it is assumed that the specific speaker speech recognition function works for a speaker registered in advance.

  In the case of a call classified as “normal state”, the memory a00 (the speaker use environment classification for speaker A in FIG. The level of the reception volume reference data of the speaker stored in the “extension telephone”, the ID is “10”, and the call function is “normal”) is compared with the level of the digitized sampling reception volume data. If there is, the volume changing unit 15 changes the received volume to the reference level, and the received voice is reproduced with the volume changed from the handset 24 of the extension telephone 19A via the extension interface unit 13 and the extension telephone interface unit 21. .

  Further, when the speaker A performs an operation for changing the reception volume by the volume button 27 of the extension telephone 19A during a call, the terminal control unit 23 of the extension telephone 19A, as shown in steps S16 and S17, A command for requesting increase / decrease is transmitted to the main device 10, and the main control unit 18 in the main device 10 sets the change amount according to the command to the reference level by the volume control unit for each speaker in the volume changing unit 15. In addition to the changed reception volume, the reception voice is reproduced with the volume changed from the handset 24 of the extension telephone 19A via the extension interface unit 13 and the extension telephone interface unit 21.

At the same time, the main control unit 18 updates the received volume data after the volume change by the volume button 27 as received volume reference level data of the speaker memory a00 of the received volume adjustment processing unit 16 for each speaker in step S18. At the same time, the received sound volume data is stored as a candidate of received sound volume reference level data in the memory a00. Then, at the end of the call, the mode value (Mod) of the accumulated reception volume data is updated as reception volume reference level data of the memory a00.
The operation by the volume button 27 and its change volume can be set in advance.

  In the case of a call classified as “forwarding phone state”, the main control unit 18 selects the memory b28 (the speaker for the speaker B in FIG. 2) from the reception volume adjustment processing unit 16 for each speaker in steps S14 and S15. The level of the received volume reference data of the speaker and the level of the digitized sampling received volume data stored in the category “Outside line”, ID “1111111”, and Call function “Normal”). If there is a difference, the volume changing unit 15 changes the level to the received volume reference level, and the received voice is reproduced on the outside line 11A through the exchange processing unit 14 and the outside line interface unit 12 with the changed volume.

  Further, when the speaker B performs an operation for changing the reception volume (for example, predetermined PB signal transmission) during a call from the outside line of the destination, as shown in steps S16 and S17, the main control unit 18 , Receiving and recognizing the operation signal, which is a command for requesting increase / decrease in volume from the outside line 11B via the outside line interface 12, and adjusting the received volume for each speaker by the volume changing unit 15 according to the command. In addition to the received sound volume changed to the reference level by the means, the received sound is reproduced with the volume changed to the external line 11A via the exchange processing unit 14 and the external line interface unit 12.

At the same time, the main control unit 18 updates the received sound volume data after the operation for changing the received sound volume from the outside line in step S18 as received sound volume reference level data of the speaker memory a28 of the received sound volume adjustment processing unit 16 for each speaker. At the same time, the received sound volume data is also stored as a candidate of received sound volume reference level data in the memory a28. Then, at the end of the call, the mode value (Mod) of the stored reception volume data is updated as reception volume reference level data in the memory a28.
In addition, the operation for changing the reception volume from the outside line and the change volume can be set in advance.
The volume adjustment value for the transfer telephone state can be set in advance.

  In the case of a call classified as “hands-free state”, the memory a01 (the speaker use environment classification for speaker A in FIG. Comparing the level of the received volume reference data of the speaker stored in the “extension telephone”, the ID “10”, and the call function “hands-free”) with the level of the digitized sampled received volume data, If there is a difference, the volume is changed to the received volume reference level by the volume changing unit 15 and the received voice is changed with the volume changed from the speaker 25 of the extension telephone 19A via the extension interface unit 13 and the extension telephone interface unit 21. Reproduce.

  Further, when the speaker A performs an operation for changing the reception volume by the volume button 27 of the extension telephone 19A during a call, the terminal control unit 23 of the extension telephone 19A, as shown in steps S16 and S17, A command for requesting increase / decrease is transmitted to the main device 10, and the main control unit 18 in the main device 10 sets the change amount according to the command to the reference level by the volume control unit for each speaker in the volume changing unit 15. In addition to the changed reception volume, the reception voice is reproduced with the volume changed from the handset 24 of the extension telephone 19A via the extension interface unit 13 and the extension telephone interface unit 21.

  When the speaker A performs an operation for changing the reception volume by the volume button 27 of the extension telephone 19A during a call, the terminal control unit 23 of the extension telephone 19A displays the volume as shown in steps S16 and S17. A command for requesting increase / decrease is transmitted to the main device 10, and the main control unit 18 in the main device 10 uses the volume change unit 15 as a reference for the change according to the command by the reception volume adjustment unit for each speaker. In addition to the reception volume changed to the level, the reception voice is reproduced with the volume changed from the speaker 25 of the extension telephone 19A through the extension interface unit 13 and the extension telephone interface unit 21.

At the same time, the main control unit 18 updates the received volume data after the volume change by the volume button 27 as received volume reference level data of the speaker memory a01 of the received volume adjustment processing unit 16 for each speaker in step S18. At the same time, the received sound volume data is stored as a candidate of received sound volume reference level data in the memory a01. Then, at the end of the call, the mode value (Mod) of the accumulated reception volume data is updated as reception volume reference level data in the memory a01.
The operation by the volume button 27 and its change volume can be set in advance.

Thereafter, even when the call environment changes during a call (for example, from a normal state to a hands-free state) or when a speaker is changed (for example, a speaker A to a speaker C), the main control unit 18 performs steps S11 and S12, The alternate call environment or the alternate speaker is identified, and a series of reception volume adjustment processing according to each call environment is performed at any time.
Further, at the time of the end of the call in each call environment, the mode value (Mod) of the received call volume data is updated as the received volume reference level data in the memory, so that the next call in the call environment is performed.
