Description

[Technical field]

[0001] The present invention relates to a communication device and an information terminal that perform short-range wireless communication. [Background technology]

[0002] In recent years, devices have been devised that use Bluetooth to receive voice from a speech translation device equipped with a microphone and translate the voice. Such information terminals are configured to receive voice by receiving an Audio State Change signal from the speech translation device and turning on SCO (Synchronous Connection Oriented), a communication path for playing voice. The speech translation device then performs a process to close the communication path by SCO by sending an Audio State Change signal again. Such a procedure for establishing a communication path for voice is specified in the standardization specifications for Bluetooth communication (see Non-Patent Document 1 below). [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] IEEE802.15 Summary of the Invention [Problem to be solved by the invention]

[Figure 6] 1 is a diagram illustrating an example of a hardware configuration of a voice input device 100 and an information terminal 200 according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The embodiments of the present disclosure will be described with reference to the accompanying drawings. Whenever possible, the same parts are designated by the same reference numerals and redundant description will be omitted.

[0010] Fig. 1 is a diagram showing the appearance of a voice input device 100 according to the present disclosure. As shown in Fig. 1, the voice input device 100 includes a speaker 101, a microphone 102, a Bluetooth status LED 103, a battery status LED 104, a Japanese voice input button 105, a foreign language voice input button 106, a volume up button 107, a volume down button 108, and a power switch 109.

[0011] The speaker 101 is a part that outputs sounds such as control sounds.

[0012] The microphone 102 is a part for inputting voice.

[0013] The Bluetooth status LED 103 is a part that lights up to indicate that communication between the information terminal and the device is established via Bluetooth. When the LED is not lit, this indicates that communication is not established. However, this is not necessarily limited to this.

[0014] The battery status LED 104 is a part that indicates the battery status by lighting up. When it flashes, it indicates that the remaining battery power is low.

[0015] Japanese voice input button 105 is an operation unit for inputting Japanese voice. When the user continues to press this Japanese voice input button 105 for a predetermined time, Bluetooth communication unit 111 transmits a predetermined remote control signal (AVRCP event signal) to the information terminal. Then, when a communication path for voice is established based on the remote control signal, the user can input Japanese voice from microphone 102.

[0016] The foreign language voice input button 106 is an operation unit for inputting voice in a foreign language. When the user presses the foreign language voice input button 106, the Bluetooth communication unit 111 transmits a predetermined remote control signal to the information terminal 200. Then, when a communication path for voice is established based on the remote control signal, the user can input voice in a foreign language from the microphone 102.

[0017] The volume down button 108 and the volume up button 107 are buttons for adjusting the volume of the sound output from the speaker 101 .

[0018] The power switch 109 is a switch for turning the power on and off.

[0019] By operating such a voice input device 100, a user can transmit voice input from a microphone 102 to an information terminal, and have the information terminal perform translation processing of the voice.

[0020] 2 is a block diagram showing the functional configuration of the voice input device 100 and the information terminal 200. The voice input device 100 includes a Bluetooth communication unit 111 as a function thereof. The information terminal 200 receives a remote control signal and voice transmitted from the voice input device 100, executes processing according to the remote control signal, and translates the received voice into a specified language.

[0021] The information terminal 200 includes a Bluetooth communication unit 201 , a voice recognition unit 202 , a machine translation unit 203 , and a voice synthesis unit 204 .

[0022] The Bluetooth communication unit 201 is a part that communicates with the voice input device 100 .

[0023] The voice recognition unit 202 is a part that recognizes voice transmitted from the voice input device 100. The voice recognition unit 202 has a Japanese language recognition function and a foreign language recognition function, and performs recognition processing according to each language. For example, when Japanese is designated as the recognition target according to a remote control signal, the voice recognition unit 202 activates the Japanese language recognition function and converts the voice into Japanese text information.

[0024] The machine translation unit 203 is a part that translates the recognized voice into a specified language. The machine translation unit 203 translates from a language (e.g., Japanese) that the speech recognition unit 202 has designated as a recognition target to a predetermined language (e.g., English). For example, the machine translation unit 203 translates into another specified language (e.g., English) based on text information of a language (e.g., Japanese) that the speech recognition unit 202 has designated as a recognition target. The machine translation unit 203 outputs the translated language as text information.

[0025] The voice synthesis unit 204 is a part that generates voice in the translated language. The generated voice is output from the output unit 206. Note that the Bluetooth communication unit 201 may transmit the voice generated by the voice synthesis unit 204 to the voice input device 100 to play it again in the voice input device 100.

[0026] The output unit 206 is a part that outputs the voice generated by the voice synthesis unit 204, and is, for example, a speaker.

[0027] Next, the operation of the voice input device 100 and the information terminal 200 thus configured will be described. Fig. 3 is a diagram showing the processing sequence. It is assumed that the voice input device 100 and the information terminal 200 have been paired in advance for Bluetooth communication.

[0028] In the voice input device 100, the user continues to press the Japanese voice input button 105 for a predetermined time. The Bluetooth communication unit 111 recognizes the pressing of the Japanese voice input button 105 and transmits an AVRCP Start signal to the information terminal 200 (S102). This AVRCP Start signal indicates one control signal of the Audio Video Remote Control Profile (AVRCP). AVRCP is one of the Bluetooth profiles (standard specifications), and is a standard profile for remotely controlling a television or audio device, and is an audio / video remote control profile. It is generally used for remote control such as playing, pausing, stopping music, and skipping stations. In the present disclosure, this remote control signal is used to start establishment of a communication path for voice from the information terminal 200.

[0029] In the information terminal 200, when the Bluetooth communication unit 201 receives the AVRCP Start signal, it transmits a SCO Open signal, which is a SCO (Synchronous Connection Oriented) connection request, to the voice input device 100, and a communication path is established by SCO (S103).

[0030] In the voice input device 100, the Bluetooth communication unit 111 transmits a SCO Open Result signal to the information terminal 200 (S104). The SCO Open Result signal is a signal indicating that a voice communication path has been established.

[0031] In the information terminal 200, when the Bluetooth communication unit 201 receives the SCO Open Result signal, it activates the voice recognition unit 202 and starts voice recognition (S105).

[0032] When a communication path by SCO is established between the voice input device 100 and the information terminal 200, the user inputs voice from the microphone 102, and the voice input device 100 transmits the voice to the information terminal 200 by A2DP (Advanced Audio Distribution Profile) (S106).

[0033] As long as the user continues to press the Japanese voice input button 105, a communication path via SCO is established between the voice input device 100 and the information terminal 200. When the user releases the Japanese voice input button 105 (S108), the Bluetooth communication unit 111 transmits a SCO Close signal to the information terminal 200 to open the communication path via SCO (S109). Upon receiving the SCOClose signal, the information terminal 200 similarly transmits a SCO Close signal to the voice input device 100 (S110). In the present disclosure, the SCO Close signal is a signal for opening the communication path via SCO. This releases the communication path via SCO.

[0034] In the information terminal 200, after transmitting and receiving the SCO Close signal, the Bluetooth communication unit 201 ends the function of the voice recognition unit 202 to end the voice recognition (S113). The machine translation unit 203 and the voice synthesis unit 204 translate the recognized text information and generate voice from it, and the translated voice is output from the output unit 206.

[0035] In this way, by having the information terminal 200 carry out the SCOOpen process, it is possible to prevent a situation in which a communication path cannot be established due to differences in the model of the information terminal 200. The above process shows the process when the Japanese voice input button 105 is continuously pressed, but the same process can also be carried out when the foreign language voice input button 106 is continuously pressed. Also, although the SCO close process is carried out by continuously pressing and then releasing the button, this is not limiting, and an SCO connection request button, release button, etc. may also be provided.

[0036] When processing by switching between Japanese voice and foreign language voice, an AVRCP Forward signal and / or an AVRCP Backward signal may be used instead of the AVRCPStart signal, as described below. In addition, when the voice input device 100 includes a Japanese voice input button 105 and a foreign language voice input button 106 as shown in Fig. 1, either an AVRCP Forward signal or an AVRCP Backward signal may be transmitted in response to pressing of each button.

[0037] FIG. 4 is a flowchart showing the operation of the voice input device 100 which switches between the AVRCP Forward signal and the AVRCP Backward signal in response to the Japanese voice input button 105 and the foreign language voice input button 106.

[0038] The Bluetooth communication unit 111 determines whether the Japanese voice input button 105 or the foreign language voice input button 106 has been pressed, based on an internal control signal transmitted from each button (S201, S202).

[0039] When the Japanese voice input button 105 is not pressed and the foreign language voice input button 106 is continuously pressed, the Bluetooth communication unit 111 transmits an AVRCPForward signal to the information terminal 200 (S203). Then, when the Bluetooth communication unit 111 receives a SCOOpen signal from the information terminal 200, it transmits a SCO Open Result signal to the information terminal 200. This establishes a communication path for voice by SCO, and input of foreign language voice starts (S204). Thereafter, communication by SCO is performed (S207). That is, the voice is streamed by A2DP.

[0040] Thereafter, when the user releases the Japanese voice input button 105 or the foreign language voice input button 106 (S208), the Bluetooth communication unit 111 receives an internal control signal indicating the release. The Bluetooth communication unit 111 is triggered by the internal control signal within the device to transmit a SCOClose signal to the information terminal 200. This releases the communication path via SCO, and the communication connection is terminated (S209).

[0041] Also, in step S201, if the Japanese voice input button 105 is pressed (the foreign language voice input button 106 is not pressed), the Bluetooth communication unit 111 transmits an AVRCP Backward signal to the information terminal 200 (S205), and when a communication connection is established via SCO, Japanese voice input is started (S206).

[0042] In this way, by switching between sending either an AVRCP Forward signal or an AVRCP Backward signal in response to pressing two buttons, information terminal 200 can notify whether Japanese is to be translated into English or a foreign language is to be translated into Japanese.

[0043] Next, a description will be given of the operation of information terminal 200. Fig. 5 is a flow chart showing the operation of information terminal 200 for switching between Japanese translation and foreign language translation.

[0044] In the information terminal 200, the Bluetooth communication unit 201 has already been paired with the voice input device 100, and monitors the event command transmitted from the voice input device 100 (S301). Then, when the Bluetooth communication unit 201 receives an event command (S302), it determines whether the event command is an AVRCP Forward signal or an AVRCP Backward signal (S303 and S306).

[0045] When the Bluetooth communication unit 201 receives the AVRCP Forward signal, it transmits a SCO Open signal to the voice input device 100 to establish a communication path for voice by SCO and start a SCO connection (S304). Then, the Bluetooth communication unit 201 starts the voice recognition unit 202 for foreign language translation (S305).

[0046] On the other hand, when the Bluetooth communication unit 201 receives the AVRCP Backward signal, it transmits a SCO Open signal to the voice input device 100 to establish a communication path for voice by SCO and start a SCO connection (S307). Then, the Bluetooth communication unit 201 starts the voice recognition unit 202 for Japanese translation (S308).

[0047] When the Bluetooth communication unit 201 receives an event command signal other than the AVRCP Forward signal and the AVRCP Backward signal, it performs processing accordingly.

[0048] When the information terminal 200 receives a SCO connection disconnection process (SCOClose signal) from the voice input device 100, it transmits a SCO Close signal to the voice input device 100 and performs the disconnection process. After that, the machine translation unit 203 translates the recognized voice, the voice synthesis unit 204 generates the voice, and the output unit 206 outputs the voice.

[0049] Next, the effects of the voice input device 100 and the information terminal 200 in the present disclosure will be described. The voice input device 100 is a communication device that performs voice communication with the information terminal 200 through short-range wireless communication such as Bluetooth communication. In the voice input device 100, the Bluetooth communication unit 111 is a communication control unit that transmits a remote control signal to the information terminal 200 to request the information terminal 200 to establish a communication path for voice communication by SCO. In the present disclosure, the establishment request is made by a command signal for remotely controlling the information terminal 200, for example, by transmitting an AVRCPStart signal, an AVRCP Forward signal, or an AVRCP Backward signal. In particular, the input language can be specified by using the AVRCP Forward signal or the AVRCP Backward signal as a first remote control signal and a second remote control signal.

[0050] Then, the Bluetooth communication unit 111 receives a SCO Open signal, which is a communication path establishment signal for establishing a communication path by SCO, from the information terminal 200. After that, the Bluetooth communication unit 111 is connected by SCO and performs audio communication by SCO.

[0051] This allows an audio communication path such as SCO to be established from the information terminal 200, and makes it possible to avoid a state in which a communication path for audio communication cannot be connected due to differences in the model of the information terminal 200. Note that, in the present disclosure, SCO, which is a communication connection for audio communication, is given as an example, but the present disclosure is not limited to this, and can be applied to the establishment of a communication path that cannot be recognized by the information terminal 200.

[0052] In the present disclosure, the Bluetooth communication unit 111 functions as a communication control unit that releases the communication path. That is, the Bluetooth communication unit 111 can release the connection by SCO by transmitting a SCOClose signal to the information terminal 200.

[0053] In the present disclosure, the voice input device 100 includes buttons for accepting user operations, such as a Japanese voice input button 105 and / or a foreign language voice input button 106.

[0054] When the Japanese voice input button 105 is pressed, the Bluetooth communication unit 111 transmits an AVRCP Start signal (or an AVRCP Forward signal or an AVRCP Backward signal) to the information terminal 200 for remote control of an establishment request. When the Japanese voice input button 105 is pressed for a predetermined time and then released, the Bluetooth communication unit 111 transmits an SCO Close signal to the information terminal 200 to perform establishment and release. This allows SCO connection and release to be performed with a simple operation.

[0055] Moreover, the information terminal 200 disclosed herein is a device that performs short-distance wireless communication by Bluetooth communication with the voice input device 100. In this information terminal 200, the Bluetooth communication unit 201 functions as a communication connection unit, and upon receiving a remote control signal for establishing a communication path by SCO from the voice input device 100, transmits a SCOOpen signal, which is an event signal for the voice communication path by SCO, to the voice input device 100. This allows the communication path to be established by SCO.

[0056] This information terminal 200 processes the voice sent through the communication path by SCO. In this disclosure, a voice recognition unit 202 performs recognition processing on the voice, a machine translation unit 203 performs translation processing, and a voice synthesis unit 204 generates voice in the translated language.

[0057] In addition, in this information terminal 200, the Bluetooth communication unit 201 receives an event signal corresponding to a button from the voice input device 100. Here, the event signal is an AVRCP Forward signal or an AVRCP Backward signal. In the present disclosure, when the information terminal 200 receives an AVRCP Forward signal, it activates a foreign language recognition function in the voice recognition unit 202 (processing unit), and when it receives an AVRCP Backward signal, it activates a Japanese language recognition function in the voice recognition unit 202.

[0058] This allows the recognition function appropriate for the language to be translated to be activated. Of course, this is not limited to language recognition and translation functions, and can be applied to other functions.

[0059] The block diagrams used in the description of the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized by using one device that is physically or logically combined, or may be realized by using two or more devices that are physically or logically separated and directly or indirectly connected (for example, by wire, wirelessly, etc.). The functional blocks may be realized by combining the one device or the multiple devices with software.

In either case, as described above, there is no particular limitation on the method of realization.
