[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, like components are designated by like reference numerals, and their description will be omitted where appropriate.

[0013] (First embodiment) FIG. 1 is a diagram illustrating an example of the functional configuration of an information processing device 10 according to the first embodiment. The information processing device 10 according to this embodiment includes a call control unit 110 and a voice recognition unit 130. The call control unit 110 disables transmission of a voice signal including at least the driver's speech to a call partner based on the fact that the detection result of a detection unit that detects the driver's actions while the driver of a mobile vehicle is on a call satisfies a predetermined condition. The voice recognition unit 130 acquires voice data of the driver's speech when transmission of the voice signal to the call partner is disabled.

[0014] FIG. 2 is a diagram showing an overview of an information processing method according to this embodiment. The information processing method according to this embodiment is executed by one or more computers. The information processing method according to this embodiment includes a call control step S10 and a voice recognition step S20. In the call control step S10, the one or more computers disable transmission of a voice signal including at least the driver's speech to the other party of the call based on the fact that the detection result of a detection unit that detects the driver's behavior while the driver of the mobile body is talking satisfies a predetermined condition. In the voice recognition step S20, the one or more computers acquire voice data from the driver's speech while transmission of the voice signal to the other party of the call is disabled.

[0015] The information processing method according to this embodiment can be executed by the information processing device 10 according to this embodiment.

[0016] 3 is a diagram showing a usage environment of the communication device 50 according to this embodiment. A user can make a call with another person via the communication device 50. A call can be made between the communication device 50 and the communication device 52 of the other party via a telephone line or a communication network. The call between the communication device 50 and the communication device 52 of the other party is preferably a wireless call.

[0017] The communication device 50 is not particularly limited, but is preferably a device that allows the user to make hands-free calls, i.e., to make calls without using hands. This allows the driver to make calls while driving a mobile vehicle. The communication device 50 is preferably, for example, a headset. That is, the communication device 50 is preferably wearable on the driver's head. However, the communication device 50 may also be a mobile terminal such as a smartphone or a terminal mounted on a mobile vehicle. These terminals also allow hands-free calls via speakerphone. The configuration of the communication device 52 is not particularly limited. The communication device 52 may or may not be a device that allows hands-free calls.

[0018] Fig. 4 is a diagram illustrating an example of the functional configuration of a communication device 50 according to this embodiment. The communication device 50 according to this embodiment includes an information processing device 10, a detection unit 20, a sound collection unit 22, and a sound output unit 32. In the example of Fig. 4, the information processing device 10 further includes a transmission unit 150. The transmission unit 150 transmits an audio signal representing the user's voice to the communication device 52 of the other party.

[0019] The hardware configuration of the information processing device 10 will be described below. Each functional component of the information processing device 10 (call control unit 110, voice recognition unit 130, and transmission unit 150) may be realized by hardware that realizes each functional component (e.g., hardwired electronic circuitry, etc.), or may be realized by a combination of hardware and software (e.g., a combination of an electronic circuitry and a program that controls it, etc.). Below, a case where each functional component of the information processing device 10 is realized by a combination of hardware and software will be further described.

[0020] FIG. 5 is a diagram illustrating a computer 1000 for realizing the information processing device 10. The computer 1000 is any computer. For example, the computer 1000 is a System On Chip (SoC). The computer 1000 may be a dedicated computer designed to realize the information processing device 10, or may be a general-purpose computer. Furthermore, the information processing device 10 may be realized by one computer 1000 or by a combination of multiple computers 1000.

[0021] The computer 1000 includes a bus 1020, a processor 1040, a memory 1060, a storage device 1080, an input / output interface 1100, and a network interface 1120. The bus 1020 is a data transmission path through which the processor 1040, the memory 1060, the storage device 1080, the input / output interface 1100, and the network interface 1120 transmit and receive data to and from each other. However, the method of interconnecting the processor 1040 and other components is not limited to bus connection. The processor 1040 may be any of various processors, such as a central processing unit (CPU), a graphics processing unit (GPU), or a field-programmable gate array (FPGA). The memory 1060 is a main storage device implemented using a random access memory (RAM) or the like. The storage device 1080 is an auxiliary storage device implemented using a solid state drive (SSD), a memory card, a read-only memory (ROM), or the like.

[0022] The input / output interface 1100 is an interface for connecting the computer 1000 to an input / output device. For example, an input device such as a keyboard and an output device such as a display are connected to the input / output interface 1100. The input / output interface 1100 may be connected to the input device or the output device wirelessly or by wire. In the example of FIG. 4, a detection unit 20, a sound collection unit 22, and a sound output unit 32 are connected to the input / output interface 1100 of the computer 1000 that realizes the information processing device 10.

[0023] The network interface 1120 is an interface for connecting the computer 1000 to a network. Examples of such a communication network include a local area network (LAN), a wide area network (WAN), and a telephone network. The method by which the network interface 1120 connects to the network is preferably a wireless connection.

[0024] The storage device 1080 stores program modules that realize each functional component of the information processing device 10. The processor 1040 reads each of these program modules into the memory 1060 and executes them to realize the function corresponding to each program module.

[0025] The communication device 50 and the information processing device 10 can be used by a driver of a mobile object. That is, the user of the communication device 50 and the information processing device 10 is the driver of the mobile object. The mobile object is not particularly limited, but may be, for example, a vehicle. Examples of the vehicle include a bicycle, a motorcycle, a car with three or more wheels, etc.

[0026] The detection unit 20 is a sensor for detecting the driver's movements. Examples of the sensor include an acceleration sensor and a camera. The detection unit 20 is, for example, an acceleration sensor worn by the driver. The sensor is worn on the driver's head, for example. The sensor may be provided in a headset or a helmet worn by the driver. If the sensor is an acceleration sensor, the movement of the driver's head can be detected as a gesture. If the sensor is a camera, by analyzing an image captured by the camera, a change in the orientation of the camera due to the movement of the driver's head can be detected, and the movement of the driver's head can be detected as a gesture.

[0027] The sound collection unit 22 is, for example, a microphone. The sound collection unit 22 is provided so as to be able to acquire at least the voice uttered by the driver of the vehicle. The microphone (sound collection unit) used for a call may also serve as a microphone (sound collection unit) for the voice recognition unit 130 to acquire voice data. In this case, one microphone can be used for both a call and a voice operation. However, the microphone used for a call may be provided separately from the microphone for the voice recognition unit 130 to acquire voice data. In other words, the communication device 50 may include multiple sound collection units 22.

[0028] The voice picked up by the sound collection unit 22 used for the call is sent to the other party via the transmission unit 150 under the control of the call control unit 110 during the call. However, the voice picked up by the sound collection unit 22 used for the call may be sent to the other party after undergoing preprocessing such as noise removal. An audio signal containing at least the contents of the driver's speech is called a "speech signal."

[0029] The sound collection unit 22, through which the voice recognition unit 130 acquires voice data, acquires voice and converts it into voice data. The voice data indicates the waveform of the voice acquired by the sound collection unit 22. The voice data is input to the information processing device 10 from the sound collection unit 22. Note that A / D conversion of the voice signal may be performed by the sound collection unit 22 or by the information processing device 10. The voice recognition unit 130 of the information processing device 10 can detect voice commands uttered by the user by performing voice recognition processing on the voice data acquired by the sound collection unit 22.

[0030] Voice commands include voice operation commands and voice trigger commands. Voice operation commands are commands that indicate operation content. When the voice recognition unit 130 detects a voice operation command, it executes a process associated with the voice operation command. Examples of processes associated with a voice operation command include changing the output volume of the sound output unit 32, starting a call, ending a call, etc. However, the processes associated with voice operation commands are not limited to these examples.

[0031] The voice trigger command is a command for starting to accept a voice operation command. The voice trigger command is a so-called wake word, which is a predetermined word. For example, when the voice recognition unit 130 detects the voice trigger command, the voice recognition unit 130 becomes ready to accept a voice operation command for a predetermined time period from the time of the detection.

[0032] Examples of the sound output unit 32 include a speaker, an earphone, a headphone, etc. When the sound output unit 32 is an earphone or a headphone, the sound output unit 32 is attached to a driver, and the driver can hear the sound from the sound output unit 32. The sound output unit 32 is controlled by the information processing device 10 and is configured to output various sounds. The information processing device 10 outputs, for example, a sound received from the other party on the call to the sound output unit 32.

[0033] An example of the flow of using the communication device 50 will be described below. When a user starts a call, the information processing device 10 transmits the user's speech signal acquired from the sound collection unit 22 to the communication device 52. The information processing device 10 also outputs the voice of the call partner received from the communication device 52 from the sound output unit 32. In this way, the user can talk to the call partner.

[0034] For example, if a driver wants to increase the volume of the sound output during a call, it is preferable to operate it by voice, since it is difficult to do so with one's hands. However, if the driver simply issues a voice command, the voice command may be heard by the other party, which may cause the other party to distrust the other party.

[0035] Therefore, the driver performs a predetermined action (for example, a predetermined gesture). When this action is detected by the detection unit 20, transmission of the speech signal to the other party is disabled. In this state, if the driver utters a voice command, the other party can perform the operation without the voice command being heard.

[0036] 6 and 7 are flowcharts illustrating the flow of processing executed by the information processing device 10 according to this embodiment.

[0037] In step S101, the call control unit 110 determines whether a predetermined call start operation has been performed. The call start operation is, for example, the utterance of a voice operation command such as "Call Mr. / Ms. XX." When the voice recognition unit 130 detects the utterance of the voice operation command, the call control unit 110 acquires information indicating the detected voice operation command from the voice recognition unit 130, and can identify that a call start operation has been performed. However, the call start operation may also be an operation of pressing a button or the like provided on the communication device 50.

[0038] Step S101 is repeated until a call start operation is performed.

[0039] If a call start operation has been performed (Yes in step S101), in step S102, the call control unit 110 starts a call between the designated call partner and the driver. During the call, the call control unit 110 transmits the driver's speech signal acquired by the sound collection unit 22 to the call partner via the transmission unit 150, and causes the sound output unit 32 to output audio based on the audio signal received from the call partner. The sound output unit 32 may continue to output audio based on the audio signal received from the call partner until the call is stopped.

[0040] In the example of FIG. 6, in step S102, the voice recognition unit 130 also stops accepting voice operation commands. That is, the voice recognition unit 130 stops accepting voice operation commands indicating operation contents when the driver starts talking. In this stopped state, even if a voice operation command is uttered, the voice recognition unit 130 does not recognize it. This makes it possible to avoid erroneously recognizing an utterance directed to the other party as a voice operation command. Note that if acceptance of voice operation commands has already been stopped at the time step S102 is to be executed, the voice recognition unit 130 maintains that state.

[0041] The voice recognition unit 130 may start accepting voice operation commands based on the driver uttering a voice trigger command, which is a command for starting acceptance of voice operation commands, during a call. By doing so, if it is okay for the caller to hear the command, voice operation becomes possible as is. However, the processing of the information processing device 10 is not limited to this example. During a call, acceptance of voice operation commands may not be started unless the detection result by the detection unit 20 satisfies the invalid condition, as will be described later.

[0042] After step S102, the call control unit 110 continues to monitor the driver's gesture and detects that the invalid condition is satisfied. In the example of FIG. 6, in step S106 following step S102, the call control unit 110 detects the driver's gesture, i.e., movement. For example, the call control unit 110 can detect that the driver has made a gesture by moving his or her head by analyzing the detection result by the detection unit 20. Specifically, when the detection signal output from the detection unit 20 reaches or exceeds a predetermined level, the call control unit 110 determines that some kind of gesture has been made. Step S106 is repeated until it is detected that some kind of gesture has been made.

[0043] When it is detected that a gesture has been made (Yes in step S106), in step S108, the call control unit 110 determines whether or not the detection result by the detection unit 20 (i.e., the signal that detected the gesture) satisfies a predetermined condition (referred to as an "invalid condition"). The invalid condition is a condition that is satisfied when the driver performs a predetermined action.

[0044] The invalid condition is preferably a condition corresponding to the driver making a predetermined neck movement. This allows the driver to make that movement without interfering with driving. For example, the invalid condition is a condition corresponding to the driver shaking his / her head up and down. That is, if the detection unit 20 is an acceleration sensor, the invalid condition is the detection of consecutive downward acceleration and upward acceleration. However, the invalid condition and the predetermined movement are not limited to this example. Note that shaking the head from side to side can occur as a driving movement, so it is preferable not to treat it as a predetermined movement.

[0045] The predetermined action is not limited to a gesture, but it is preferable that the invalidation condition is not a condition for the driver's speech, and that the detection unit 20 is not a microphone. In this way, transmission of the speech signal can be invalidated without being detected by the other party.

[0046] In step S108, if it is determined that the detection result by the detection unit 20 does not satisfy the invalid condition (No in step S108), the process returns to step S106, and gesture monitoring continues.

[0047] On the other hand, if the detection result by the detection unit 20 satisfies the disable condition in step S108 (Yes in step S108), the transmission of the speech signal to the communication partner is disabled (step S109). That is, even if the sound collection unit 22 acquires the driver's speech, the audio signal is not sent to the communication partner. However, sounds other than the driver's speech, such as hold music or environmental sounds, may be sent to the communication partner.

[0048] In the example of Fig. 7, in step S109, the voice recognition unit 130 further starts accepting voice operation commands based on the fact that the detection result of the detection unit 20 satisfies the invalid condition while the driver is talking. This allows operation without the voice commands being heard by the other party on the call. However, acceptance of voice operation commands does not have to start unless a voice trigger command is detected.

[0049] After step S109, if the voice recognition unit 130 detects a voice operation command (Yes in step S110), the voice recognition unit 130 executes a process corresponding to the detected voice operation command (step S111). After the process is executed, step S112 is executed.

[0050] In step S110, if a predetermined time has elapsed without the voice recognition unit 130 detecting a voice operation command (timeout) (No in step S110), the process proceeds to step S112.

[0051] In step S112, the call control unit 110 determines whether or not the disablement termination condition is satisfied. A first example of the disablement termination condition is that a predetermined time has elapsed since the transmission of the speech signal to the call partner was disabled. A second example of the disablement termination condition is that at least one process based on a voice operation command has been executed. A third example of the disablement termination condition is that the detection result of the detection unit 20 that detects the driver's behavior satisfies a predetermined condition. This predetermined condition may be the same as or different from the disablement condition.

[0052] If the disablement termination condition is satisfied (Yes in step S112), the transmission of the speech signal to the communication partner is enabled (step S113). That is, the transmission of the voice signal including the driver's speech content acquired by the sound collection unit 22 to the communication partner is resumed.

[0053] Furthermore, in the example of FIG. 7, in step S113, the voice recognition unit 130 stops accepting voice operation commands.

[0054] In step S112, if a predetermined time has elapsed without the invalidation termination condition being satisfied (timeout) (No in step S112), the process returns to step S110.

[0055] Unless an operation to end the call is performed, the process may return to step S106 after step S113.

[0056] 6 and 7 show an example in which steps S106 and S108 are performed regardless of the state of the mobile object. However, call control unit 110 may obtain information indicating whether the mobile object is stopped or not, and use this obtained information to determine whether to perform steps S106 and S108. For example, call control unit 110 obtains a control signal of the mobile object or a detection result by a sensor provided in the mobile object as information indicating whether the mobile object is stopped or not.

[0057] If the mobile object is stopped, the driver can disable transmission of the speech signal to the other party by a method other than a gesture (for example, by pressing a button on the communication device 50). Therefore, the communication control unit 110 may perform the processes of steps S106 and S108 described above when the mobile object is not stopped, and may monitor whether a predetermined button on the communication device 50 has been pressed when the mobile object is stopped. In this case, if the button has been pressed, the communication control unit 110 then performs the process of step S109.

[0058] As described above, according to this embodiment, when the driver of the vehicle is making a call, the call control unit 110 disables transmission of an audio signal including at least the driver's speech to the other party based on the fact that the detection result of the detection unit that detects the driver's behavior satisfies a predetermined condition. Therefore, it is possible to achieve both calls and speech-based operations.

[0059] (Second embodiment) 8 is a diagram showing an overview of a communication device 50 and a communication system 70 according to the second embodiment. The communication device 50 according to this embodiment is the same as the communication device 50 according to the first embodiment except for the points described below.

[0060] The communication device 50 according to this embodiment is a device used in a communication system 70 that enables hands-free communication with a call partner via a communication device 60. The communication device 50 includes a sound collection unit 22, a transmission unit 150, and a detection unit 20. The sound collection unit 22 collects the user's voice. The transmission unit 150 transmits an audio signal representing the user's voice to the communication device 60, and the detection unit 20 detects a predetermined action of the user. When the detection unit 20 detects the predetermined action, the transmission unit 150 continues transmitting an audio signal to the communication device 60, while transmitting a control signal to the communication device 60 to stop transmission of an audio signal including at least the user's speech content to the call partner.

[0061] 9 is a diagram illustrating an example of a usage environment of a call system 70 according to this embodiment. The functional configuration of the call device 50 according to this embodiment is illustrated in FIG. 4, similarly to the first embodiment. However, the transmitting unit 150 according to this embodiment transmits an audio signal indicating the user's voice to the communication device 60 instead of transmitting the audio signal to the call device 52 of the other party. Then, the audio signal is transmitted from the communication device 60 to the call device 52.

[0062] Furthermore, the voice recognition unit 130 may be provided in the communication device 60 instead of in the information processing device 10 of the communication device 50. In this case, the voice signal acquired by the sound collection unit 22 is transmitted to the communication device 60, and the voice recognition unit 130 of the communication device 60 performs voice recognition processing.

[0063] As in the first embodiment, "the detection unit 20 detects a predetermined operation" includes determining that the detection result of the detection unit 20 satisfies the invalid condition as a result of the detection result of the detection unit 20 being processed by the information processing device 10.

[0064] The communication device 50 is, for example, a headset worn by a user. The hardware configuration of the communication device 60 is exemplified in FIG. 5 , similar to that of the information processing device 10. However, the computer 1000 that realizes the communication device 60 is, for example, a terminal such as a smartphone. A storage device 1080 of the computer 1000 that realizes the communication device 60 stores a program module that realizes the functions of the communication device 60 of this embodiment.

[0065] The call device 50 and the communication device 60 are connected via their respective input / output interfaces 1100. The connection between the call device 50 and the communication device 60 may be a wired connection or a wireless connection. It is preferable that the call between the call system 70 and the call destination call device 52 be a wireless call.

[0066] 10 is a diagram illustrating a flow of using the call system 70. When a call is started between the call system 70 and the call device 52 (step S201), the transmitting unit 150 of the call device 50 transmits the user's speech signal acquired by the sound collecting unit 22 to the communication device 60. The communication device 60 also transmits the speech signal received from the call device 50 to the call device 52. An audio signal indicating the content of the speech of the call partner is also transmitted from the call device 52 to the communication device 60. The communication device 60 transmits the audio signal received from the call device 52 to the call device 50, and audio based on the audio signal is output from the sound output unit 32 of the call device 50. This allows a conversation between the user and the call partner.

[0067] Then, when the user performs a predetermined action and the action is detected by the detection unit 20 (step S202), the call control unit 110 of the communication device 50 causes the transmission unit 150 to transmit a stop signal (step S203). The stop signal is a control signal that causes the communication device 60 to stop transmission to the other party. The stop signal is transmitted from the transmission unit 150 to the communication device 60, and the communication device 60 that has received the stop signal disables transmission of a speech signal to the communication device 52 of the other party (step S204). That is, even if the communication device 60 acquires a voice signal from the communication device 50, it will no longer transmit a voice signal including at least the content of the user's speech to the communication device 52.

[0068] However, even after the disabling, the sound collection unit 22 is not disabled, and the communication device 60 can receive a voice signal from the communication device 50. Therefore, the user can utter a voice operation command (for example, "hang up the phone") and send it to the communication device 60 (step S205).

[0069] When the communication device 60 detects a voice operation command in the voice signal received from the communication device 50 (step S206), the communication device 60 executes a process corresponding to the voice operation command (step S207).

[0070] According to this embodiment, when the detection unit 20 detects a predetermined operation, the transmission unit 150 continues transmitting an audio signal to the communication device 60, while transmitting a control signal to the communication device 60 to stop transmission of an audio signal including at least the content of the user's speech to the other party. Therefore, the same effects as those of the first embodiment can be obtained.

[0071] Although the embodiments and examples have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than those described above can also be adopted.
