Abstract

A recording buffer (81) stores sound data which indicates input sound. A playback buffer (82) stores sound data which indicates output sound. A transmission buffer (83) stores sound data to be transmitted to a communication destination device which receives sound data from an external device by wireless communication. A control means (86) transmits the sound data stored in the transmission buffer (83) to the communication destination device by wireless communication, and deletes the transmitted sound data from the transmission buffer (83). Further, when it is assessed that sound data is being transmitted to the communication destination device, the control means (86) causes the transmission buffer (83) to store the sound data stored in the recording buffer (81) and also causes the playback buffer (82) to store that sound data.

Description

送信音声モニタ方法、音声入出力装置および送信音声モニタ用プログラムTransmission voice monitoring method, voice input / output device, and transmission voice monitoring program
　本発明は、無線送信される音声をモニタする送信音声モニタ方法、音声入出力装置および送信音声モニタ用プログラムに関する。 The present invention relates to a transmission voice monitoring method, a voice input / output device, and a transmission voice monitoring program for monitoring a voice transmitted wirelessly.
　遠隔地からセンタへ情報を通知し、その情報を記録するような場面では、一般的に、遠隔地の担当者が通知用の端末を操作することでセンタに情報を通知する方法が用いられる。 In a situation where information is notified from a remote location to the center and the information is recorded, a method is generally used in which a person in charge at the remote location notifies the center by operating a notification terminal.
　一方、両手がふさがっている場合など、端末を操作できない場面も存在する。このような場面では、担当者が発した音声をセンタに無線で通知し、センタ側にその音声を認識させることで、情報を通知する方法が用いられることがある。このような方法を用いることで、担当者は、作業をしながら必要な音声情報をセンタに通知できるようになる。 On the other hand, there are scenes where the terminal cannot be operated, such as when both hands are occupied. In such a situation, there may be used a method of notifying the center of the voice generated by the person in charge and notifying the center of the voice by notifying the center of the voice. By using such a method, the person in charge can notify the center of necessary voice information while working.
　したがって、このような方法を用いる場合は、センタに音声情報が正しく無線通信されているか確認することが重要になる。 Therefore, when using such a method, it is important to confirm whether voice information is correctly wirelessly communicated to the center.
　図８は、無線通信の適否を確認する方法の一例を示す説明図である。図８に示す方法は、音声入出力装置７０からの音声情報を通信相手先装置７３が無線で受信したことを確認すると、その音声情報をそのまま音声入出力装置７０に返信する方法である。 FIG. 8 is an explanatory diagram showing an example of a method for confirming the suitability of wireless communication. The method shown in FIG. 8 is a method of returning the voice information to the voice input / output device 70 as it is when it is confirmed that the communication partner device 73 has received the voice information from the voice input / output device 70 wirelessly.
　図８に示す方法では、音声入出力装置７０は、入力部７１から音声が入力されると、その音声を示す情報を通信相手先装置７３に無線送信する。通信相手先装置７３は、音声情報を受信すると、その音声情報をそのまま音声入出力装置７０に返信する。音声入出力装置７０は、通信相手先装置７３から音声情報を受信すると、その音声情報を出力部７２に出力させる。このように、利用者は、出力部７２が出力した音声情報を確認することで、通信相手先装置７３に音声情報が正しく無線通信できたことを確認できる。 In the method shown in FIG. 8, when a voice is input from the input unit 71, the voice input / output device 70 wirelessly transmits information indicating the voice to the communication partner device 73. When receiving the voice information, the communication partner apparatus 73 returns the voice information to the voice input / output apparatus 70 as it is. When the voice input / output device 70 receives voice information from the communication partner device 73, the voice input / output device 70 causes the output unit 72 to output the voice information. Thus, the user can confirm that the voice information has been correctly wirelessly communicated to the communication partner apparatus 73 by checking the voice information output by the output unit 72.
　また、通信相手先装置側で受信した音声情報を表示することで、音声情報が正しく無線通信されていることを確認する方法も知られている。特許文献１には、受信した音声情報を表示する端末装置が記載されている。特許文献１に記載された端末装置は、受信したデジタル音声信号を音声認識してテキストデータへ変換し、変換したテキストデータを表示部に表示する。 Also known is a method of confirming that the voice information is correctly wirelessly communicated by displaying the voice information received on the communication partner apparatus side. Patent Document 1 describes a terminal device that displays received audio information. The terminal device described in Patent Document 1 recognizes a received digital voice signal as voice and converts it into text data, and displays the converted text data on a display unit.

　上述するように、音声データの通信相手先装置が、受信した音声データをスピーカで再生したり、受信した音声データをディスプレイに表示したりすることにより、無線送信された音声データをモニタすることは可能である。 As described above, it is possible for the communication partner apparatus for audio data to monitor the audio data transmitted wirelessly by reproducing the received audio data with a speaker or displaying the received audio data on a display. Is possible.
　しかし、音声データを再生してモニタする方法を用いた場合、モニタしている間は、通信相手先装置のスピーカがモニタ処理に制限されてしまう。また、特許文献１に記載された端末装置のように、音声データをディスプレイに表示してモニタする方法を用いた場合、モニタしている間は、利用者が常にディスプレイを見ていなければならない（アイズビジー）。 However, when the method of reproducing and monitoring audio data is used, the speaker of the communication partner apparatus is limited to the monitoring process while monitoring. Moreover, when using the method of displaying and monitoring audio data on a display as in the terminal device described in Patent Document 1, the user must always look at the display while monitoring ( Eyes busy).
　また、遠隔地にある通信相手先装置に音声データを送る場合、音声データを送信する利用者は、そもそも、再生される音声を聞くこともできず、また、ディスプレイに表示される情報を見ることもできない。 In addition, when sending audio data to a remote device at a remote location, the user who sends the audio data cannot hear the audio to be played in the first place, and sees the information displayed on the display. I can't.
　また、図８に示す方法を用いる場合、音声データを通信相手先装置に必ず送信し、その応答を待たなければなければならないという問題がある。 Further, when the method shown in FIG. 8 is used, there is a problem that the voice data must be transmitted to the communication partner apparatus and wait for a response.
　図９は、無線通信の適否を確認するとともに、入力された音声を確認する方法を示す説明図である。図９に示す方法では、通信相手先装置７３が音声入出力装置７４からの音声情報を無線で受信したことを確認すると、その音声情報をそのまま音声入出力装置７４に返信する。さらに、音声入出力装置７４は、入力された音声をそのまま自装置の出力部７２に出力する。 FIG. 9 is an explanatory diagram showing a method of confirming the suitability of wireless communication and confirming the input voice. In the method shown in FIG. 9, when the communication partner apparatus 73 confirms that the voice information from the voice input / output apparatus 74 has been received wirelessly, the voice information is sent back to the voice input / output apparatus 74 as it is. Furthermore, the voice input / output device 74 outputs the input voice as it is to the output unit 72 of the own device.
　図９に示す方法では、音声入出力装置７４は、入力部７１から音声が入力されると、その音声を示す情報を通信相手先装置７３に無線送信する。通信相手先装置７３は、音声情報を受信すると、その音声情報をそのまま音声入出力装置７４に返信する。一方、音声入出力装置７４は、通信相手先装置７３から音声情報を受信したときには、その音声情報を出力部７２に出力する。さらに、音声入出力装置７４は、入力部７１から入力された音声を、そのまま出力部７２に出力する。 In the method shown in FIG. 9, when a voice is input from the input unit 71, the voice input / output device 74 wirelessly transmits information indicating the voice to the communication partner device 73. Upon receiving the voice information, the communication partner apparatus 73 returns the voice information to the voice input / output device 74 as it is. On the other hand, when the voice input / output device 74 receives voice information from the communication partner device 73, the voice input / output device 74 outputs the voice information to the output unit 72. Further, the voice input / output device 74 outputs the voice input from the input unit 71 to the output unit 72 as it is.
　図９に示す方法を用いれば、入力した音声を随時モニタすることは可能である。しかし、図９に示す方法では、入力した音声を通信相手先装置へ無線通信にて送信できたか否かを確認することはできないという問題がある。 If the method shown in FIG. 9 is used, it is possible to monitor the input voice at any time. However, the method shown in FIG. 9 has a problem that it cannot be confirmed whether or not the input voice can be transmitted to the communication partner apparatus by wireless communication.
　そこで、本発明は、通信相手先装置へ無線通信にて送信できた音声データの内容を、通信相手先装置からの応答を待つことなく、その音声データが示す音声でモニタできる送信音声モニタ方法、音声入出力装置および送信音声モニタ用プログラムを提供することを目的とする。 Therefore, the present invention provides a transmission voice monitoring method capable of monitoring the content of voice data transmitted by radio communication to a communication partner apparatus with the voice indicated by the voice data without waiting for a response from the communication partner apparatus, An object of the present invention is to provide a voice input / output device and a transmission voice monitor program.
　本発明による送信音声モニタ方法は、外部装置からの音声データを受信する通信相手先装置に対して無線送信する音声をモニタする送信音声モニタ方法であって、通信相手先装置に対して送信される音声データを記憶する送信バッファに記憶されたその音声データを無線通信により通信相手先装置に送信し、送信した音声データを送信バッファから削除し、通信相手先装置へ音声データの送信が行われていると判定した場合、入力された音声を示す音声データを記憶する録音バッファに記憶されたその音声データを送信バッファに記憶させるとともに、出力手段に出力させる音声を示す音声データを記憶する再生バッファに、録音バッファに記憶された音声データを記憶させ、再生バッファに記憶された音声データを音声として出力手段に出力させることを特徴とする。 A transmission voice monitoring method according to the present invention is a transmission voice monitoring method for monitoring a voice wirelessly transmitted to a communication partner apparatus that receives voice data from an external device, and is transmitted to the communication partner apparatus.

　以下、本発明の実施形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
実施形態１．
　図１は、本発明による音声入出力装置の第１の実施形態の構成例を示すブロック図である。本実施形態の音声入出力装置１０は、入力部１１と、出力部１２と、制御部１３と、録音バッファ１４と、送信バッファ１５と、再生バッファ１６とを備えている。 Embodiment 1. FIG.
FIG. 1 is a block diagram showing a configuration example of a first embodiment of a voice input / output device according to the present invention. The voice input / output device 10 of this embodiment includes an input unit 11, an output unit 12, a control unit 13, a recording buffer 14, a transmission buffer 15, and a reproduction buffer 16.
　音声入出力装置１０は、無線通信により通信相手先装置２０と通信を行う。通信相手先装置２０は、外部装置からの音声データを無線通信により受信する装置である。通信相手先装置２０は、受信処理部２１を備えており、受信処理部２１は、外部装置（ここでは、音声入出力装置１０）から受信した音声データに対する各種処理（例えば、音声認識処理、音声データ返信処理等）を行う。 The voice input / output device 10 communicates with the communication partner device 20 by wireless communication. The communication partner device 20 is a device that receives voice data from an external device by wireless communication. The communication partner device 20 includes a reception processing unit 21. The reception processing unit 21 performs various types of processing (for example, voice recognition processing, voice processing) on voice data received from an external device (here, the voice input / output device 10). Data reply processing).
　入力部１１は、外部からの音声を入力して、録音バッファ１４に入力された音声を示す音声データを記憶する。入力部１１への音声の入力は、例えば、マイクロフォンなどの入力装置により実現される。 The input unit 11 inputs external audio and stores audio data indicating the audio input to the recording buffer 14. The input of sound to the input unit 11 is realized by an input device such as a microphone, for example.
　出力部１２は、再生バッファ１６に記憶された音声データを音声として出力する。出力部１２からの音声の出力は、例えば、スピーカなどの入力装置により実現される。 The output unit 12 outputs the audio data stored in the reproduction buffer 16 as audio. The audio output from the output unit 12 is realized by an input device such as a speaker, for example.
　録音バッファ１４は、入力部１１に入力される音声を示す音声データを記憶する。再生バッファ１６は、出力部１２から出力される音声を示す音声データを記憶する。また、送信バッファ１５は、通信相手先装置２０に対して送信される音声データを記憶する。音声データは、デジタルデータであってもよく、アナログデータであってもよい。 The recording buffer 14 stores audio data indicating the audio input to the input unit 11. The reproduction buffer 16 stores audio data indicating the audio output from the output unit 12. The transmission buffer 15 stores audio data transmitted to the communication partner apparatus 20. The audio data may be digital data or analog data.
　制御部１３は、送信バッファ１５に記憶された音声データを無線通信により通信相手先装置２０に送信し、送信した音声データを送信バッファ１５から削除する。ここで、通信相手先装置２０に送信するとは、通信相手先装置２０に直接音声データを送信する場合だけでなく、通信相手先装置２０へ送信するために経由する装置（例えば、基地局等）へ送信する場合も含む。 The control unit 13 transmits the voice data stored in the transmission buffer 15 to the communication partner apparatus 20 by wireless communication, and deletes the transmitted voice data from the transmission buffer 15. Here, the transmission to the communication partner apparatus 20 is not only a case where voice data is directly transmitted to the communication partner apparatus 20, but also a device (for example, a base station) through which transmission is performed to the communication partner apparatus 20 This includes the case of sending to.
　また、制御部１３は、音声データが通信相手先装置２０へ送信できているか否かを判定する。具体的には、制御部１３は、送信バッファ１５に予め定めた量の空き領域が存在する場合、通信相手先装置２０へ音声データの送信が行われていると判定する。これは、音声データが送信されると、送信された音声データが送信バッファ１５から削除されるためである。音声データが通信相手先装置２０へ送信できている場合、制御部１３は、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させるとともに、その音声データを再生バッファ１６にも記憶させる。 Further, the control unit 13 determines whether or not the voice data can be transmitted to the communication partner apparatus 20. Specifically, when there is a predetermined amount of free space in the transmission buffer 15, the control unit 13 determines that audio data is being transmitted to the communication partner apparatus 20. This is because the transmitted audio data is deleted from the transmission buffer 15 when the audio data is transmitted. When the audio data can be transmitted to the communication partner apparatus 20, the control unit 13 stores the audio data stored in the recording buffer 14 in the transmission buffer 15 and also stores the audio data in the reproduction buffer 16.
　このように、制御部１３が、音声データの送信が行われていると判定した場合に、その音声データを再生バッファ１６にも記憶させる。そのため、この音声データを示す音声を出力部１２から出力させることにより、通信相手先装置２０へ無線通信にて送信できた音声データの内容を、通信相手先装置２０からの応答を待つことなくモニタできる。 As described above, when the control unit 13 determines that the audio data is being transmitted, the audio data is also stored in the reproduction buffer 16. Therefore, by outputting the voice indicating the voice data from the output unit 12, the contents of the voice data that can be transmitted to the communication partner apparatus 20 by wireless communication can be monitored without waiting for a response from the communication partner apparatus 20. it can.
　また、制御部１３は、データ送信ができなかった回数をカウントしてもよい。データ送信ができない場合、送信バッファ１５に記憶された音声データが削除されないため、送信バッファ１５にデータが蓄積される。例えば、音声の入力よりも音声データの送信が遅い場合、録音バッファ１４に記憶された音声データは、送信バッファ１５に記憶されるまで保留される。この場合、録音バッファ１４に保留された音声データが再生バッファ１６へ記憶されるまでに、遅延が生じることになる。すなわち、入力された音声の出力が遅延することになる。 Further, the control unit 13 may count the number of times data transmission could not be performed. If data transmission is not possible, the audio data stored in the transmission buffer 15 is not deleted, and therefore the data is accumulated in the transmission buffer 15. For example, if the transmission of audio data is slower than the input of audio, the audio data stored in the recording buffer 14 is held until it is stored in the transmission buffer 15. In this case, a delay occurs until the audio data held in the recording buffer 14 is stored in the reproduction buffer 16. That is, the output of the input voice is delayed.
　そこで、データ送信できなかった回数が予め定めた回数を超えていた場合、制御部１３は、録音バッファ１４、送信バッファ１５および再生バッファ１６に記憶された音声データを消去してもよい。このようにすることで、入力された音声が出力されるまでの遅延を解消することが可能になる。 Therefore, when the number of times data transmission could not be performed exceeds a predetermined number, the control unit 13 may erase the audio data stored in the recording buffer 14, the transmission buffer 15, and the reproduction buffer 16. By doing so, it becomes possible to eliminate the delay until the input voice is output.
　入力部１１と、出力部１２と、制御部１３とは、プログラム（送信音声モニタ用プログラム）に従って動作するコンピュータのＣＰＵによって実現される。例えば、プログラムは、音声入出力装置１０の記憶部（図示せず）に記憶され、ＣＰＵは、そのプログラムを読み込み、プログラムに従って、入力部１１、出力部１２および制御部１３として動作してもよい。また、入力部１１と、出力部１２と、制御部１３とは、それぞれが専用のハードウェアで実現されていてもよい。 The input unit 11, the output unit 12, and the control unit 13 are realized by a CPU of a computer that operates in accordance with a program (transmission voice monitor program). For example, the program may be stored in a storage unit (not shown) of the voice input / output device 10, and the CPU may read the program and operate as the input unit 11, the output unit 12, and the control unit 13 according to the program. . Further, the input unit 11, the output unit 12, and the control unit 13 may each be realized by dedicated hardware.
　また、録音バッファ１４と、送信バッファ１５と、再生バッファ１６とは、例えば、ＦＩＦＯ（First-In/First-Out）メモリなどにより実現される。 Further, the recording buffer 14, the transmission buffer 15, and the reproduction buffer 16 are realized by, for example, a FIFO (First-In / First-Out) memory.
　次に、本実施形態の音声入出力装置の動作を説明する。図２は、本実施形態の音声入出力装置の動作例を示すフローチャートである。 Next, the operation of the voice input / output device of this embodiment will be described. FIG. 2 is a flowchart showing an operation example of the voice input / output device of the present embodiment.
　入力部１１に音声が入力されると、入力部１１は、入力された音声を変換した音声データを、録音バッファ１４に記憶させる（ステップＳ１）。制御部１３は、音声データが送信できているか否かを判定する。すなわち、制御部１３は、送信状態をチェックする（ステップＳ２）。具体的には、制御部１３は、送信バッファ１５に予め定めた量の空き領域が存在するか否か判定する。 When the voice is input to the input unit 11, the input unit 11 stores the voice data obtained by converting the input voice in the recording buffer 14 (step S1). The control unit 13 determines whether audio data can be transmitted. That is, the control unit 13 checks the transmission state (step S2). Specifically, the control unit 13 determines whether or not a predetermined amount of free space exists in the transmission buffer 15.
　音声データが送信できている場合（ステップＳ３におけるイエス）、制御部１３は、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させる（ステップＳ４）。また、制御部１３は、その音声データを再生バッファ１６にも記憶させる（ステップＳ５）。そして、出力部１２は、再生バッファ１６に記憶された音声データを音声として出力する（ステップＳ６）。 If the audio data can be transmitted (Yes in step S3), the control unit 13 stores the audio data stored in the recording buffer 14 in the transmission buffer 15 (step S4). The control unit 13 also stores the audio data in the reproduction buffer 16 (step S5). Then, the output unit 12 outputs the audio data stored in the reproduction buffer 16 as audio (step S6).
　一方、音声データが送信できていない場合（ステップＳ３におけるノー）、制御部１３は、データ送信できなかった回数をカウントする（ステップＳ７）。データ送信できなかった回数が予め定めた回数を超えた場合（ステップＳ８におけるイエス）、制御部１３は、録音バッファ１４、送信バッファ１５および再生バッファ１６に記憶された音声データを消去する（ステップＳ９）。一方、データ送信できなかった回数が予め定めた回数を超えていない場合（ステップＳ８におけるノー）、処理を終了する。 On the other hand, when the voice data cannot be transmitted (No in step S3), the control unit 13 counts the number of times the data cannot be transmitted (step S7). When the number of times that data could not be transmitted exceeds a predetermined number (Yes in Step S8), the control unit 13 erases the audio data stored in the recording buffer 14, the transmission buffer 15 and the reproduction buffer 16 (Step S9). ). On the other hand, when the number of times data transmission could not be performed does not exceed the predetermined number (No in step S8), the process is terminated.
　以上のように、本実施形態によれば、制御部１３が、送信バッファ１５に記憶された音声データを無線通信により通信相手先装置２０に送信し、送信した音声データを送信バッファ１５から削除する。また、制御部１３が、通信相手先装置２０へ音声データの送信が行われていると判定した場合、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させるとともに、再生バッファ１６に、録音バッファ１４に記憶されたデータと同じ音声データを記憶させる。そして、出力部１２が、再生バッファ１６に記憶された音声データを音声として出力する。 As described above, according to the present embodiment, the control unit 13 transmits the voice data stored in the transmission buffer 15 to the communication partner apparatus 20 by wireless communication, and deletes the transmitted voice data from the transmission buffer 15. . In addition, when the control unit 13 determines that the audio data is being transmitted to the communication partner apparatus 20, the audio data stored in the recording buffer 14 is stored in the transmission buffer 15, and the reproduction buffer 16 The same audio data as the data stored in the recording buffer 14 is stored. Then, the output unit 12 outputs the audio data stored in the reproduction buffer 16 as audio.
　具体的には、制御部１３は、送信バッファ１５に予め定めた量の空き領域が存在する場合に通信相手先装置へ音声データの送信が行われていると判定する。以上のような構成により、通信相手先装置２０へ無線通信にて送信できた音声データの内容を、通信相手先装置２０からの応答を待つことなく、その音声データが示す音声でモニタできる。 Specifically, the control unit 13 determines that audio data is being transmitted to the communication partner apparatus when a predetermined amount of free space exists in the transmission buffer 15. With the configuration as described above, the contents of the voice data transmitted to the communication partner apparatus 20 by wireless communication can be monitored with the voice indicated by the voice data without waiting for a response from the communication partner apparatus 20.
　また、制御部１３が、通信相手先装置２０へ音声データの送信ができなかった回数をカウントしてもよい。そして、カウントした回数が予め定めた回数を超えた場合に、制御部１３は、録音バッファ１４、送信バッファ１５および再生バッファ１６に記憶された音声データを消去してもよい。このような構成により、モニタする音声の遅延を解消できる。 Further, the control unit 13 may count the number of times that voice data cannot be transmitted to the communication partner apparatus 20. Then, when the counted number exceeds a predetermined number, the control unit 13 may delete the audio data stored in the recording buffer 14, the transmission buffer 15, and the reproduction buffer 16. With such a configuration, the delay of the sound to be monitored can be eliminated.
実施形態２．
　図３は、本発明による音声入出力装置の第２の実施形態の構成例を示すブロック図である。なお、第１の実施形態と同様の構成については、図１と同一の符号を付し、説明を省略する。本実施形態の音声入出力装置３０は、入力部１１と、出力部１２と、制御部１３と、録音バッファ１４と、送信バッファ１５と、再生バッファ１６と、受信バッファ１７とを備えている。 Embodiment 2. FIG.
FIG. 3 is a block diagram showing a configuration example of the second embodiment of the voice input / output device according to the present invention. In addition, about the structure similar to 1st Embodiment, the code | symbol same as FIG. 1 is attached | subjected and description is abbreviate | omitted. The audio input / output device 30 of this embodiment includes an input unit 11, an output unit 12, a control unit 13, a recording buffer 14, a transmission buffer 15, a reproduction buffer 16, and a reception buffer 17.
　すなわち、本実施形態の音声入出力装置３０は、受信バッファ１７をさらに備えている点において第１の実施形態の音声入出力装置１０と異なる。それ以外については、第１の実施形態と同様である。受信バッファ１７は、例えば、ＦＩＦＯ（First-In/First-Out）メモリなどにより実現される。 That is, the voice input / output device 30 of this embodiment is different from the voice input / output device 10 of the first embodiment in that it further includes a reception buffer 17. The rest is the same as in the first embodiment. The reception buffer 17 is realized by, for example, a FIFO (First-In / First-Out) memory.
　音声入出力装置３０は、無線通信により通信相手先装置４０と通信を行う。通信相手先装置４０は、外部装置からの音声データを無線通信により受信すると、その音声データに対応する音声データを外部装置に送信する装置である。受信した音声データに対応する音声データとは、同一の音声であってもよく、受信した音声データに何らかの処理を行ったデータであってもよい。 The voice input / output device 30 communicates with the communication partner device 40 by wireless communication. The communication partner device 40 is a device that, when receiving voice data from an external device by wireless communication, transmits voice data corresponding to the voice data to the external device. The audio data corresponding to the received audio data may be the same audio or may be data obtained by performing some processing on the received audio data.
　具体的には、通信相手先装置４０は、受信処理部４１と送信処理部４２とを備えている。受信処理部４１は、外部装置（ここでは、音声入出力装置３０）から受信した音声データに対する各種処理を行う。送信処理部４２は、受信処理部４１が処理した音声データを外部装置（ここでは、音声入出力装置３０）に送信する。なお、通信相手先装置４０が音声データに対して行う処理は、第１の実施形態の通信相手先装置２０が行う処理と同様であってもよい。 Specifically, the communication partner apparatus 40 includes a reception processing unit 41 and a transmission processing unit 42. The reception processing unit 41 performs various processes on the audio data received from the external device (here, the audio input / output device 30). The transmission processing unit 42 transmits the audio data processed by the reception processing unit 41 to an external device (here, the audio input / output device 30). Note that the process performed by the communication partner apparatus 40 on the audio data may be the same as the process performed by the communication partner apparatus 20 of the first embodiment.
　受信バッファ１７は、通信相手先装置４０から受信した音声データを記憶する。具体的には、音声入出力装置３０が通信相手先装置４０から音声データを受信すると、制御部１３が、その音声データを受信バッファ１７に記憶させる。そして、制御部１３は、受信バッファ１７に記憶させたデータを、再生バッファ１６に記憶させる。 The reception buffer 17 stores voice data received from the communication partner apparatus 40. Specifically, when the voice input / output device 30 receives voice data from the communication partner device 40, the control unit 13 stores the voice data in the reception buffer 17. Then, the control unit 13 stores the data stored in the reception buffer 17 in the reproduction buffer 16.
　したがって、録音バッファ１４に記憶された音声データが再生バッファ１６に記憶され、かつ、受信バッファ１７に記憶された音声データが再生バッファ１６に記憶される場合、入力された音声と受信した音声とが合わさった音声が出力部１２から出力されることになる。 Therefore, when the audio data stored in the recording buffer 14 is stored in the reproduction buffer 16 and the audio data stored in the reception buffer 17 is stored in the reproduction buffer 16, the input audio and the received audio are The combined sound is output from the output unit 12.
　また、制御部１３は、送信バッファ１５に予め定めた量の空き領域が存在する場合に、通信相手先装置４０へ音声データの送信が行われていると判定する。このとき、制御部１３は、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させる。また、制御部１３は、受信バッファ１７に記憶された音声データと、送信バッファ１５に記憶させた音声データとを合わせた音声データを再生バッファ１６に記憶させる。 Further, the control unit 13 determines that the voice data is being transmitted to the communication partner apparatus 40 when there is a predetermined amount of free space in the transmission buffer 15. At this time, the control unit 13 stores the audio data stored in the recording buffer 14 in the transmission buffer 15. In addition, the control unit 13 causes the reproduction buffer 16 to store audio data that is a combination of the audio data stored in the reception buffer 17 and the audio data stored in the transmission buffer 15.
　一方、制御部１３は、送信バッファ１５に予め定めた量の空き領域が存在しない場合、通信相手先装置４０へ音声データの送信が行われていないと判定する。このとき、制御部１３は、受信バッファ１７に記憶された音声データを再生バッファ１６に記憶させる。 On the other hand, when there is no predetermined amount of free space in the transmission buffer 15, the control unit 13 determines that no audio data is transmitted to the communication partner apparatus 40. At this time, the control unit 13 stores the audio data stored in the reception buffer 17 in the reproduction buffer 16.
　なお、通信相手先装置４０に音声データを無線通信によって送信し、通信相手先装置４０で音声データに対する処理を行った後、音声入出力装置３０に音声データが返信されるには、一定の時間がかかる。そのため、音声入出力装置３０の利用者は、自身が入力した音声をリアルタイムで聞いた後、一定の時間経過後に、通信相手先装置４０で処理された音声データをモニタできる。 It is to be noted that a certain period of time is required for the voice data to be returned to the voice input / output device 30 after the voice data is transmitted to the communication partner device 40 by wireless communication and the voice data is processed by the communication partner device 40. It takes. Therefore, the user of the voice input / output device 30 can monitor the voice data processed by the communication partner device 40 after a predetermined time has elapsed after listening to the voice input by the user in real time.
　また、本実施形態のように、通信相手先装置４０に送信した音声データが返信される構成の場合、無線通信ができたか否か、また、無線通信はできたが通信相手先装置４０が応答を返さなかっただけか否かを判断することが可能になる。 Also, in the case of the configuration in which the voice data transmitted to the communication partner apparatus 40 is returned as in the present embodiment, whether or not the wireless communication has been performed and whether the wireless communication has been performed but the communication partner apparatus 40 has responded. It is possible to determine whether or not only was returned.
　次に、本実施形態の音声入出力装置の動作を説明する。図４及び図５は、本実施形態の音声入出力装置の動作例を示すフローチャートである。入力部１１に音声が入力されてから、制御部が送信状態をチェックするステップＳ１～ステップＳ２の処理は、図２に例示する処理と同様である。 Next, the operation of the voice input / output device of this embodiment will be described. 4 and 5 are flowcharts showing an operation example of the voice input / output device of this embodiment. The processing in steps S1 to S2 in which the control unit checks the transmission state after the voice is input to the input unit 11 is the same as the processing illustrated in FIG.
　音声データが送信できている場合（図４におけるステップＳ３におけるイエス）、制御部１３は、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させる（ステップＳ４）。また、制御部１３は、受信バッファ１７に音声データが記憶されているか否かを判定する（ステップＳ１４）。 When the audio data can be transmitted (Yes in step S3 in FIG. 4), the control unit 13 stores the audio data stored in the recording buffer 14 in the transmission buffer 15 (step S4). Further, the control unit 13 determines whether audio data is stored in the reception buffer 17 (step S14).
　受信バッファ１７に音声データが記憶されていない場合（ステップＳ１５におけるノー）、制御部１３は、録音バッファ１４に記憶された音声データを再生バッファ１６に記憶させる（ステップＳ５）。一方、受信バッファ１７に音声データが記憶されている場合（ステップＳ１５におけるイエス）、制御部１３は、受信バッファ１７に記憶された音声データと、録音バッファ１４に記憶された音声データとを混合して、再生バッファ１６に記憶させる（ステップＳ１６）。そして、出力部１２は、再生バッファ１６に記憶された音声データを音声として出力する（ステップＳ６）。 When no audio data is stored in the reception buffer 17 (No in step S15), the control unit 13 stores the audio data stored in the recording buffer 14 in the reproduction buffer 16 (step S5). On the other hand, when audio data is stored in the reception buffer 17 (Yes in step S15), the control unit 13 mixes the audio data stored in the reception buffer 17 with the audio data stored in the recording buffer 14. And stored in the reproduction buffer 16 (step S16). And the output part 12 outputs the audio | voice data memorize | stored in the reproduction | regeneration buffer 16 as an audio | voice (step S6).
　一方、音声データが送信できていない場合（ステップＳ３におけるノー）、制御部１３は、受信バッファ１７に音声データが記憶されているか否かを判定する（図５におけるステップＳ１１）。受信バッファ１７に音声データが記憶されている場合（ステップＳ１２におけるイエス）、制御部１３は、受信バッファ１７に記憶された音声データを再生バッファ１６に記憶させる（ステップＳ１３）。その後、ステップＳ７以降の処理が行われる。 On the other hand, when the audio data cannot be transmitted (No in Step S3), the control unit 13 determines whether or not the audio data is stored in the reception buffer 17 (Step S11 in FIG. 5). When audio data is stored in the reception buffer 17 (Yes in step S12), the control unit 13 stores the audio data stored in the reception buffer 17 in the reproduction buffer 16 (step S13). Thereafter, the processing after step S7 is performed.
　一方、受信バッファ１７に音声データが記憶されていない場合（ステップＳ１２におけるノー）には、ステップＳ７以降の処理が行われる。なお、送信できなかった回数をカウントして、各バッファの内容をクリアするか否かを判定するステップＳ７～ステップＳ９の処理は、図２に例示する処理と同様である。 On the other hand, when the audio data is not stored in the reception buffer 17 (No in step S12), the processing after step S7 is performed. Note that the processes in steps S7 to S9 for counting the number of times of transmission failure and determining whether or not to clear the contents of each buffer are the same as the processes illustrated in FIG.
　以上のように、本実施形態によれば、制御部１３が、通信相手先装置４０へ音声データの送信が行われていると判定した場合、録音バッファ１４に記憶された音声データを送信バッファ１５に記憶させるとともに録音バッファ１４に記憶された音声データと受信バッファ１７に記憶された音声データとを再生バッファ１６に記憶させる。一方、制御部１３が、通信相手先装置４０へ音声データの送信が行われていないと判定した場合、受信バッファ１７に記憶された音声データを再生バッファ１６に記憶させる。よって、第１の実施形態の効果に加え、自身が入力した音声をリアルタイムで聞いた後、一定の時間経過後に、通信相手先装置４０で処理された音声データをモニタできる。 As described above, according to the present embodiment, when the control unit 13 determines that audio data is being transmitted to the communication partner apparatus 40, the audio data stored in the recording buffer 14 is transmitted to the transmission buffer 15. And the audio data stored in the recording buffer 14 and the audio data stored in the reception buffer 17 are stored in the reproduction buffer 16. On the other hand, when the control unit 13 determines that the audio data is not transmitted to the communication partner apparatus 40, the audio data stored in the reception buffer 17 is stored in the reproduction buffer 16. Therefore, in addition to the effect of the first embodiment, the voice data processed by the communication partner apparatus 40 can be monitored after a certain time has elapsed after listening to the voice input by itself in real time.
　図６は、本発明による音声入出力装置の第２の実施形態の変形例を示すブロック図である。図６に示す例では、音声入出力装置３０が、図３に例示する通信相手先装置４０の代わりに音声認識装置５０と無線通信していることを示す。 FIG. 6 is a block diagram showing a modification of the second embodiment of the voice input / output device according to the present invention. In the example illustrated in FIG. 6, the voice input / output device 30 is performing wireless communication with the voice recognition device 50 instead of the communication partner device 40 illustrated in FIG. 3.
　図６に例示する音声認識装置５０は、音声認識部５１と、音声合成部５２とを備えている。音声認識部５１は、音声入出力装置３０から受信した音声データの音声認識を行い、音声認識結果として、音声データを変換したテキストを生成する。音声合成部５２は、音声認識部５１が生成したテキストを音声データに変換し、変換した音声データを無線通信によりに音声入出力装置３０に送信する。 The voice recognition device 50 illustrated in FIG. 6 includes a voice recognition unit 51 and a voice synthesis unit 52. The voice recognition unit 51 performs voice recognition of the voice data received from the voice input / output device 30, and generates a text obtained by converting the voice data as a voice recognition result. The voice synthesizer 52 converts the text generated by the voice recognizer 51 into voice data, and transmits the converted voice data to the voice input / output device 30 by wireless communication.
　このように、音声データの送信先が音声認識装置の場合、音声入出力装置３０は、音声認識装置５０が音声認識した結果の音声データを受信できる。このような音声データを受信することで、利用者は、例えば、入力した音声が正しく認識されているか、音声データから不要語などの情報が削除されているか、などを確認することが可能になる。 As described above, when the transmission destination of the voice data is the voice recognition device, the voice input / output device 30 can receive the voice data as a result of the voice recognition performed by the voice recognition device 50. By receiving such voice data, the user can check whether the input voice is correctly recognized or whether information such as unnecessary words is deleted from the voice data, for example. .
