图2为本发明实施例提供的一种切换通话模式的方法。如图2所示，该方法包括：FIG. 2 is a method for switching a call mode provided by an embodiment of the present invention. As shown in Figure 2, the method includes:

步骤201、连接有外设耳机的第一终端与远端设备建立通话连接。Step 201: The first terminal connected with the peripheral headset establishes a call connection with the remote device.

本实施例中的第一终端连接有外设耳机，该外设耳机可以为有线耳机，也可以为无线耳机。当该外设耳机为有线耳机时，该耳机可以通过第一终端上的耳机插孔与该第一终端有线连接。当该外设耳机为无线耳机时，该耳机可以通过蓝牙或Wi-Fi等无线技术与该第一终端无线连接。本发明各实施例中的远端设备指的是可以与该第一终端建立通话连接的终端。The first terminal in this embodiment is connected with a peripheral earphone, and the peripheral earphone may be a wired earphone or a wireless earphone. When the peripheral earphone is a wired earphone, the earphone can be wiredly connected to the first terminal through the earphone jack on the first terminal. When the peripheral headset is a wireless headset, the headset can be wirelessly connected to the first terminal through a wireless technology such as Bluetooth or Wi-Fi. The remote device in the embodiments of the present invention refers to a terminal that can establish a call connection with the first terminal.

该第一终端与远端设备建立通话连接，其中，该第一终端可以为主叫终端，也可以为被叫终端。The first terminal establishes a call connection with the remote device, wherein the first terminal may be a calling terminal or a called terminal.

步骤202、在该第一终端与远端设备建立通话连接之后，该第一终端通过该外设耳机的麦克风采集第一声音信号。Step 202: After the first terminal establishes a call connection with the remote device, the first terminal collects a first sound signal through the microphone of the peripheral earphone.

该外设耳机包括麦克风和听筒。麦克风可以用于采集用户发出的声音或者环境声音，并将采集到的声音传输给该第一终端。听筒可以将第一终端产生的声音信号或者第一终端从远端设备接收到的声音信号播放给用户听。The peripheral headset includes a microphone and an earpiece. The microphone may be used to collect the sound made by the user or the ambient sound, and transmit the collected sound to the first terminal. The earpiece can play the sound signal generated by the first terminal or the sound signal received by the first terminal from the remote device to the user.

在该第一终端与远端设备建立通话连接之后，该第一终端通过该外设耳机的麦克风采集用户的声音，即第一声音信号。需要说明的是，在该第一终端没有与远端设备建立通话连接之前，该第一终端也可以通过该外设耳机的麦克风采集声音。例如：在该第一终端作为主叫终端呼叫远端设备，且未建立通话连接时，该外设耳机的麦克风就可以用于采集声音，此时，如果采集到用户终止呼叫的语音，第一终端可以终止该呼叫。在该第一终端作为被叫终端接收到远端设备的呼叫，且未建立通话连接时，该外设耳机的麦克风也可以用于采集声音，此时，如果采集到用户挂断该来电的语音，第一终端可以挂断该来电，如果采集到用户接听该来电的语音，第一终端可以接听该来电。此外，在第一终端处于待机状态或其它没有进行通话的状态时，外设耳机的麦克风也可以用于采集用户的声音，例如：用户可以通过外设耳机的麦克风对第一终端进行语音控制，通过语音控制该第一终端打开某个应用程序或执行某个功能。也就是说，第一终端在检测到与外设耳机建立了连接之后，就可以通过外设耳机的麦克风采集声音。当然，第一终端也可以仅在与远端设备建立通话连接之后，才通过外设耳机的麦克风采集声音。After the first terminal establishes a call connection with the remote device, the first terminal collects the user's voice, that is, the first voice signal, through the microphone of the peripheral headset. It should be noted that, before the first terminal establishes a call connection with the remote device, the first terminal may also collect sound through the microphone of the peripheral headset. For example: when the first terminal is used as the calling terminal to call the remote device and the call connection is not established, the microphone of the peripheral headset can be used to collect sound. The terminal can terminate the call. When the first terminal as the called terminal receives a call from the remote device and the call connection is not established, the microphone of the peripheral headset can also be used to collect sound. At this time, if the voice of the user hanging up the call is collected , the first terminal can hang up the incoming call, and if the voice of the user answering the incoming call is collected, the first terminal can answer the incoming call. In addition, when the first terminal is in a standby state or other states without a call, the microphone of the peripheral headset can also be used to collect the user's voice. For example, the user can perform voice control on the first terminal through the microphone of the peripheral headset, The first terminal is controlled by voice to open a certain application or execute a certain function. That is to say, after detecting that the connection with the peripheral earphone is established, the first terminal can collect sound through the microphone of the peripheral earphone. Of course, the first terminal may also collect sound through the microphone of the peripheral headset only after establishing a call connection with the remote device.

需要说明的是，当第一终端通过外设耳机的麦克风采集声音信号时，该第一终端可以通过外设耳机的听筒播放从远端设备接收的声音。It should be noted that when the first terminal collects the sound signal through the microphone of the peripheral earphone, the first terminal can play the sound received from the remote device through the earpiece of the peripheral earphone.

步骤203、该第一终端将采集到的该第一声音信号转换为第一音频数据。第一终端通过外设耳机的麦克风采集该第一声音信号，得到第一音频数据，该第一音频数据可以为模拟信号，也可以是被模数转换之后的数字信号。Step 203: The first terminal converts the collected first sound signal into first audio data. The first terminal collects the first sound signal through the microphone of the peripheral earphone to obtain first audio data, where the first audio data may be an analog signal or a digital signal after analog-to-digital conversion.

步骤204、该第一终端判断该第一音频数据是否为有效数据；若判断出该第一音频数据为非有效数据，即无效数据，则执行步骤205，若判断出该第一音频数据为有效数据，则该第一终端继续使用该外设耳机进行通话，即该第一终端采用耳机模式进行通话，使用外设耳机的麦克风采集外部声音，使用外设耳机的听筒播放声音。Step 204, the first terminal determines whether the first audio data is valid data; if it is determined that the first audio data is invalid data, that is, invalid data, then step 205 is executed, and if it is determined that the first audio data is valid data, the first terminal continues to use the peripheral headset to make a call, that is, the first terminal uses the headset mode to make a call, uses the microphone of the peripheral headset to collect external sound, and uses the earpiece of the peripheral headset to play sound.

其中，该第一终端可以通过以下任一种方式判断音频数据是否为有效数据。The first terminal may determine whether the audio data is valid data in any of the following manners.

方式一：该第一终端将音频数据与经验数据进行比对，通过比对，若判断出该音频数据为人发出的声音，则确定该音频数据为有效数据，若判断出该音频数据为背景音或环境音，则确定该音频数据为非有效数据。Mode 1: The first terminal compares the audio data with the empirical data, and through the comparison, if it is determined that the audio data is a sound made by a human, the audio data is determined to be valid data, and if it is determined that the audio data is background sound or ambient sound, the audio data is determined to be invalid data.

方式二：该第一终端识别音频数据的具体内容，若识别出该音频数据的内容为通话时用户经常说的语句，则确定所述第一音频数据为有效数据，若无法识别出该音频数据的内容，则确定该音频数据为非有效数据。Method 2: The first terminal identifies the specific content of the audio data, and if it recognizes that the content of the audio data is a sentence often said by the user during a call, the first audio data is determined to be valid data, and if the audio data cannot be identified content, it is determined that the audio data is invalid data.

方式三：该第一终端获取该音频数据与经验数据的语音类似度，若所述语音类似度大于预设阈值，则确定该音频数据为有效数据，若所述语音类似度小于或等于所述预设阈值，则确定该音频数据为非有效数据。Mode 3: The first terminal acquires the voice similarity between the audio data and the experience data, and if the voice similarity is greater than a preset threshold, the audio data is determined to be valid data, and if the voice similarity is less than or equal to the If the preset threshold is set, it is determined that the audio data is invalid data.

步骤205、该第一终端切换为通过该第一终端的麦克风采集第二声音信号。当通过外设耳机的麦克风采集到的声音为无效声音时，表示用户当前可能没有使用耳机进行通话，而是手持第一终端并在使用第一终端自身的麦克风和听筒。由此，该第一终端将耳机模式切换为正常模式，即切换为使用第一终端自身的麦克风和听筒进行通话的模式，通过第一终端自身的麦克风采集外部的声音信号，即第二声音信号。Step 205: The first terminal switches to collect the second sound signal through the microphone of the first terminal. When the sound collected by the microphone of the peripheral headset is invalid, it means that the user may not currently use the headset to make a call, but is holding the first terminal and using the microphone and the earpiece of the first terminal. As a result, the first terminal switches the headset mode to the normal mode, that is, switches to the mode of using the microphone and the earpiece of the first terminal to make a call, and collects the external sound signal through the microphone of the first terminal itself, that is, the second sound signal .

需要说明的是，当第一终端通过自身的麦克风采集声音信号时，该第一终端可以通过自身的听筒播放从远端设备接收的声音。It should be noted that when the first terminal collects the sound signal through its own microphone, the first terminal can play the sound received from the remote device through its own earpiece.

步骤205之后，该方法还可以包括步骤206。Afterstep 205 , the method may further includestep 206 .

步骤206、该第一终端将采集到的该第二声音信号转换为第二音频数据。将声音信号转换为音频数据的过程可以参见步骤203。Step 206: The first terminal converts the collected second sound signal into second audio data. The process of converting the sound signal into audio data may refer to step 203 .

步骤207、该第一终端判断该第二音频数据是否为有效数据；若判断出该第二音频数据为非有效数据，则执行步骤208；若判断出该第二音频数据为有效数据，则执行步骤210。具体判断音频数据是否为有效数据的方法可以参见步骤204中的描述。Step 207, the first terminal judges whether the second audio data is valid data; if it is judged that the second audio data is invalid data, then executesstep 208; if it judges that the second audio data is valid data, executesStep 210. For the specific method of determining whether the audio data is valid data, reference may be made to the description instep 204 .

步骤208、该第一终端比较该第一音频数据和该第二音频数据；若该第一音频数据的语音质量高于该第二音频数据的语音质量，则执行步骤209，若该第一音频数据的语音质量低于该第二音频数据的语音质量，则执行步骤210。Step 208, the first terminal compares the first audio data and the second audio data; if the voice quality of the first audio data is higher than the voice quality of the second audio data, then performstep 209, if the first audio If the voice quality of the data is lower than the voice quality of the second audio data,step 210 is executed.

步骤209、该第一终端切换为通过该外设耳机的麦克风采集声音信号。Step 209: The first terminal switches to collect sound signals through the microphone of the peripheral earphone.

当通过外设耳机的麦克风采集到的声音信号的质量高于通过第一终端自身的麦克风采集到的声音信号的质量时，表示当前用户在使用外设耳机进行通话，所以第一终端需要重新切换为外设耳机模式进行通话，即通过外设耳机的麦克风采集外部声音。可能是因为当前通话的质量不高，才导致步骤204中的误判。When the quality of the sound signal collected through the microphone of the peripheral headset is higher than the quality of the sound signal collected through the microphone of the first terminal itself, it means that the current user is using the peripheral headset to make a call, so the first terminal needs to switch again. Make a call in the peripheral headset mode, that is, collect the external sound through the microphone of the peripheral headset. The misjudgment instep 204 may be caused because the quality of the current call is not high.

步骤210、该第一终端继续使用自身的麦克风和听筒进行通话，即该第一终端继续使用自身的麦克风采集外部声音，使用自身的听筒播放声音。当通过第一终端自身的麦克风采集到的声音信号的质量高于通过外设耳机的麦克风采集到的声音信号的质量时，表示当前用户没有在使用外设耳机。可能是因为当前通话的质量不高，才导致步骤207中的误判。Step 210: The first terminal continues to use its own microphone and earpiece to make a call, that is, the first terminal continues to use its own microphone to collect external sounds, and uses its own earpiece to play sounds. When the quality of the sound signal collected through the microphone of the first terminal is higher than the quality of the sound signal collected through the microphone of the peripheral earphone, it indicates that the current user is not using the peripheral earphone. The misjudgment instep 207 may be caused because the quality of the current call is not high.

本方法实施例还可以包括：第一终端可以提示用户当前处于哪种通话模式。例如：当第一终端检测到与外设耳机处于连接状态时，可以提示用户当前处于耳机模式；当第一终端从耳机模式切换到正常模式时，可以提示用户当前处于正常模式，或者提示用户模式已切换；当第一终端从正常模式切换回耳机模式时，可以再次提示用户当前所处的模式或者提示用户模式已切换。在提示用户时，第一终端可以通过自身的显示屏进行文字或图形提示，或者通过该第一终端的扬声器或外设耳机进行语音提示。This embodiment of the method may further include: the first terminal may prompt the user which call mode is currently in. For example: when the first terminal detects that it is connected to the peripheral headset, it can prompt the user that it is currently in the headset mode; when the first terminal switches from the headset mode to the normal mode, it can prompt the user that it is currently in the normal mode, or prompt the user mode Switched; when the first terminal switches from the normal mode back to the headset mode, the user can be prompted again to the current mode or the user mode has been switched. When prompting the user, the first terminal may give a text or graphic prompt through its own display screen, or give a voice prompt through a speaker or a peripheral earphone of the first terminal.

本发明实施例，连接有外设耳机的终端在与远端设备建立通话连接之后，先使用外设耳机进行通话，并判断通过外设耳机的麦克风采集到的声音是否为有效的。如果是无效的，则自动切换到使用终端自身的麦克风和听筒进行通话，即自动切换通话模式。在切换之后，如果判断通过终端自身的麦克风采集到的声音质量低于通过外设耳机的麦克风采集到的声音质量，则终端再自动切换回耳机通话模式，即切换回使用外设耳机进行通话。由此，通过本发明实施例，可以实现通话模式的自动切换，提高终端使用的便利性。并且，本发明实施例可以将当前的通话模式以及模式切换的信息提示给用户，便于用户获知终端自动切换通话模式的行为。In the embodiment of the present invention, after establishing a call connection with the remote device, the terminal connected with the peripheral earphone first uses the peripheral earphone to make a call, and judges whether the sound collected by the microphone of the peripheral earphone is valid. If it is invalid, it will automatically switch to using the terminal's own microphone and earpiece to make a call, that is, automatically switch the call mode. After switching, if it is judged that the quality of the sound collected by the microphone of the terminal is lower than the quality of the sound collected by the microphone of the peripheral headset, the terminal automatically switches back to the headset call mode, that is, switches back to using the peripheral headset to make a call. Therefore, through the embodiments of the present invention, automatic switching of the call mode can be realized, and the convenience of using the terminal can be improved. In addition, the embodiment of the present invention can prompt the user with the information of the current call mode and the mode switching, so that the user can know the behavior of the terminal automatically switching the call mode.

下面通过图3、图4所示的实施例，以手机为例，具体描述本发明实施例的方案。The solutions of the embodiments of the present invention are described in detail below by taking a mobile phone as an example through the embodiments shown in FIG. 3 and FIG. 4 .

具体的，如图3所示，该方法可以包括如下步骤：Specifically, as shown in Figure 3, the method may include the following steps:

步骤301、手机开始进行通话。手机接收到来电呼叫之后，用户触发接听电话的操作；或者手机作为主叫，用户通过手机拨打电话。手机的处理器可以接收用户通过手机的输入单元输入的接听指令或拨打指令。Step 301, the mobile phone starts to make a call. After the mobile phone receives the incoming call, the user triggers the operation of answering the call; or the mobile phone acts as the caller, and the user makes a call through the mobile phone. The processor of the mobile phone can receive an answering instruction or a dialing instruction input by the user through the input unit of the mobile phone.

步骤302、该手机判断是否与外设耳机处于连接状态，包括判断耳机插孔是否被有线耳机占用(即判断手机与有线耳机是否处于连接状态)和/或判断手机与蓝牙耳机等无线耳机是否处于连接状态；若判断手机与外设耳机没有处于连接状态，则进入步骤308；若判断手机与外设耳机处于连接状态，则进入步骤303。Step 302: The mobile phone determines whether it is in a connected state with a peripheral headset, including judging whether the earphone jack is occupied by a wired headset (that is, judging whether the mobile phone and the wired headset are in a connected state) and/or judging whether the mobile phone and a wireless headset such as a Bluetooth headset are in a connected state. Connected state; if it is determined that the mobile phone and the peripheral headset are not in a connected state, go to step 308; if it is determined that the mobile phone and the peripheral headset are in a connected state, go to step 303.

需要说明的是，本发明实施例并不限定步骤302的执行顺序，或者，可以不包括步骤302。在有线耳机插入手机之后或者无线耳机与手机配对连接之后，手机即可获知已与外设耳机建立连接，在后续的通话过程中，手机就可以选择耳机模式，即可以在步骤301之后，进入步骤303。It should be noted that the embodiment of the present invention does not limit the execution order ofstep 302, or step 302 may not be included. After the wired headset is inserted into the mobile phone or the wireless headset is paired and connected to the mobile phone, the mobile phone can know that the connection with the peripheral headset has been established. In the subsequent call process, the mobile phone can select the headset mode, that is, afterstep 301, enter step 303.

步骤303、该手机通过外设耳机的麦克风采集外部的声音。Step 303 , the mobile phone collects external sounds through the microphone of the peripheral earphone.

步骤304、该手机将采集到的声音信号转换为第一音频数据，并可以存储该第一音频数据。例如，该手机的音频电路接收并处理外设耳机采集的声音信号，并将处理后的第一音频数据发送给手机的处理器和/或存储器，可以是实时发送，也可以是按系统预设的一定周期发送(例如每10ms发送一次)。Step 304: The mobile phone converts the collected sound signal into first audio data, and can store the first audio data. For example, the audio circuit of the mobile phone receives and processes the sound signal collected by the peripheral earphone, and sends the processed first audio data to the processor and/or memory of the mobile phone, which can be sent in real time or preset according to the system It is sent at a certain period of time (for example, every 10ms).

步骤305、该手机判断预设时间段内的第一音频数据是否为有效数据；如果是有效数据，则执行步骤306，如果是无效数据，则执行步骤307。其中，预设时间段内的第一音频数据可以为：该预设时间段内外设耳机采集到的声音转换的第一音频数据。Step 305: The mobile phone determines whether the first audio data within the preset time period is valid data; if it is valid data, then executesstep 306, and if it is invalid data, executesstep 307. Wherein, the first audio data within the preset time period may be: the first audio data converted from the sound collected by the internal and external earphones in the preset time period.

例如，该手机的处理器或音频电路判断该第一音频数据是否为有效数据。当由该音频电路来判断时，该音频电路可以将判断结果发送给该处理器。所述预设时间段可以是通话建立的最开始的一段时间，例如通话建立后的最初1秒、2秒、3秒或者5秒，具体时间的长短不做限定。For example, the processor or audio circuit of the mobile phone determines whether the first audio data is valid data. When judged by the audio circuit, the audio circuit can send the judgment result to the processor. The preset time period may be the first period of time when the call is established, for example, the first 1 second, 2 seconds, 3 seconds, or 5 seconds after the call is established, and the specific time period is not limited.

其中，手机判断音频数据是否为有效数据可以通过以下任意一种或几种方式：Among them, the mobile phone can determine whether the audio data is valid data through any one or several of the following methods:

方式一：将识别结果与经验数据(可以是专家库、智能库、经验数据库等存储了海量人声的语音数据库)比对，通过比对判定音频数据是人声(有效数据)还是背景音或环境音(无效数据)；所述的识别可以为语音识别或语义识别，也可以为对音频数据的其它算法，只要使得音频数据能够与经验数据进行对比即可。Method 1: Compare the recognition result with the experience data (it can be an expert database, an intelligent database, an experience database, etc. that store a large number of human voices), and determine whether the audio data is human voice (valid data) or background sound or Ambient sound (invalid data); the recognition can be speech recognition or semantic recognition, or other algorithms for audio data, as long as the audio data can be compared with the empirical data.

方式二：识别音频数据的具体内容，并根据具体内容判断是否为有效数据。例如：若识别出的音频数据的内容为“你好”、“你是谁”、“喂”、“说话”、“没声音”、“我是Tom”等打电话时用户常说的词句，语言不做限定，可以是中文、英文、俄文、日文等多种语音输入，则判断为有效数据；或者只要能够识别出具体内容，就可以判断为有效数据；若无法识别，则判断为无效数据。Method 2: Identify the specific content of the audio data, and determine whether it is valid data according to the specific content. For example, if the content of the identified audio data is "hello", "who are you", "hello", "speaking", "no voice", "I'm Tom" and other words that users often say when making a phone call, The language is not limited, it can be Chinese, English, Russian, Japanese and other voice input, it is judged as valid data; or as long as the specific content can be recognized, it can be judged as valid data; if it cannot be recognized, it is judged as invalid data.

方式三：通过比对识别结果与经验数据以获取语音类似度，判断语音类似度是否超过预设的语音类似度阈值，若超过该阈值则判断为有效数据，若未超过该阈值则判断为无效数据。Method 3: Obtain the voice similarity by comparing the recognition result with the empirical data, and judge whether the voice similarity exceeds the preset voice similarity threshold. If it exceeds the threshold, it is judged as valid data, and if it does not exceed the threshold, it is judged as invalid. data.

步骤306、手机保持当前通话模式为耳机模式。Step 306, the mobile phone keeps the current call mode as the headset mode.

步骤307、手机把通话模式切换为手机自身的听筒/麦克风模式，即手机使用自身的听筒和麦克风进行通话。在切换时或切换后，手机可以提示用户通话模式已切换。Step 307 , the mobile phone switches the call mode to the handset/microphone mode of the mobile phone itself, that is, the mobile phone uses its own handset and microphone to make a call. During or after switching, the mobile phone may prompt the user that the call mode has been switched.

步骤308、手机采用手机自身的听筒/麦克风模式，即手机使用自身的听筒和麦克风进行通话。Step 308 , the mobile phone adopts the handset/microphone mode of the mobile phone itself, that is, the mobile phone uses its own handset and microphone to make a call.

当用户手机与外设耳机处于连接状态，但打电话时用户不清楚当前连接状态仍使用手机本地进行通话而不使用耳机时，手机会根据实际情况自动判断该使用哪种通话模式，防止误挂断电话。并且，可以通过手机自身的音频电路和处理器实现自动切换通话模式，省去用户手动操作的步骤，且在不用增加额外的硬件的情况下即可解决误挂断电话的问题。When the user's mobile phone is connected to the peripheral headset, but the user does not know the current connection status when making a call, and still uses the mobile phone to make local calls instead of using the headset, the mobile phone will automatically determine which call mode to use according to the actual situation to prevent mistakenly hanging up Disconnect. In addition, the phone's own audio circuit and processor can automatically switch the call mode, which saves the user's manual operation steps, and can solve the problem of accidentally hanging up the phone without adding additional hardware.

在某些不常见的情况下，用户确实是使用外设耳机进行通话，但由于采集的声音信号很差(距离基站较远或背景噪音太大)，可能会导致声音信号被识别为无效输入，而被误切换为使用手机自身听筒/麦克风模式通话。为了进一步解决该问题，本实施例可以在前述方法实施例的基础上，进一步通过比较手机自身听筒/麦克风模式和耳机模式下采集的声音，确定最终通话模式并进行自动切换。具体如图4所示，在图3所示实施例的基础上，假设手机已经执行步骤307，即手机已切换为手机自身听筒/麦克风模式，在此之后，如图4所示，还可以包括如下步骤：In some uncommon cases, the user does use a peripheral headset to make a call, but due to the poor sound signal collected (far from the base station or too much background noise), the sound signal may be recognized as invalid input, It was mistakenly switched to use the handset/microphone mode of the mobile phone to make a call. In order to further solve this problem, this embodiment can determine the final call mode and perform automatic switching by comparing the sound collected in the handset/microphone mode and the earphone mode of the mobile phone on the basis of the foregoing method embodiments. Specifically, as shown in FIG. 4, on the basis of the embodiment shown in FIG. 3, it is assumed that the mobile phone has performedstep 307, that is, the mobile phone has been switched to the handset/microphone mode of the mobile phone. After that, as shown in FIG. Follow the steps below:

步骤401、手机开始使用自身的麦克风采集声音信号。例如：手机的处理器通知手机自身的麦克风开始采集外部声音，并通知音频电路开始接收并处理该麦克风采集的声音信号。Step 401 , the mobile phone starts to use its own microphone to collect sound signals. For example, the processor of the mobile phone notifies the microphone of the mobile phone to start collecting external sound, and notifies the audio circuit to start receiving and processing the sound signal collected by the microphone.

步骤402、手机将步骤401采集到的该声音信号转换为第二音频数据。Step 402, the mobile phone converts the sound signal collected instep 401 into second audio data.

步骤403、手机判断预设时间段内的第二音频数据是否为有效数据；如果是有效数据，则执行步骤404，如果是无效数据，则执行步骤405。其中，该预设时间段可以为切换通话模式之后的一段时间，例如为切换到通过手机自身麦克风采集声音之后的最初1秒、2秒、3秒或者5秒，具体时间的长短不做限定。该预设时间段的长短可以与步骤305中的一样，也可以不一样。手机判断第二音频数据是否为有效数据的方法参见前述手机判断第一音频数据是否为有效数据的方法。Step 403 , the mobile phone determines whether the second audio data within the preset time period is valid data; if it is valid data, executestep 404 , and if it is invalid data, executestep 405 . The preset time period may be a period of time after switching the call mode, for example, the first 1 second, 2 seconds, 3 seconds, or 5 seconds after switching to the phone's own microphone to collect sound, and the specific time period is not limited. The length of the preset time period may or may not be the same as that instep 305 . For the method for the mobile phone to determine whether the second audio data is valid data, refer to the aforementioned method for the mobile phone to determine whether the first audio data is valid data.

步骤404、该手机保持当前通话模式为自身听筒/麦克风模式。Step 404, the mobile phone keeps the current call mode as its own handset/microphone mode.

步骤405、该手机获取耳机模式下的该第一音频数据和手机自身听筒/麦克风模式下的该第二音频数据；具体可以有以下两种方式：Step 405, the mobile phone obtains the first audio data in the headset mode and the second audio data in the handset/microphone mode of the mobile phone; specifically, the following two methods are available:

方式一：该手机获取当前处理得到的该第二音频数据，并且从该手机的存储器中获取之前存储的耳机模式下的该第一音频数据；Mode 1: the mobile phone obtains the second audio data currently processed, and obtains the previously stored first audio data in the headset mode from the memory of the mobile phone;

方式二：该手机从存储器中获取该第一音频数据和第二音频数据，其中，该第二音频数据是在步骤402中由手机存储在自身的存储器中的。Manner 2: The mobile phone obtains the first audio data and the second audio data from the memory, wherein the second audio data is stored in the memory of the mobile phone instep 402 .

步骤406、该手机比较该第一音频数据和该第二音频数据的语音质量；例如可以通过比较语音的音量大小、清晰度等关键因子，判断该第一音频数据的语音质量是否高于该第二音频数据的语音质量，若否，则进入步骤404，若是，即当手机自身麦克风接收到的语音质量低于耳机接收到的语音质量时，则进入步骤407。Step 406, the mobile phone compares the voice quality of the first audio data and the second audio data; for example, it can be judged whether the voice quality of the first audio data is higher than that of the first audio data by comparing key factors such as the volume and clarity of the voice. 2. The voice quality of the audio data, if not, go to step 404, if yes, that is, when the voice quality received by the phone's own microphone is lower than the voice quality received by the earphone, go to step 407.

步骤407、手机将通话模式切换为耳机模式。Step 407, the mobile phone switches the call mode to the headset mode.

当用户确实是使用外设耳机进行通话，但由于语音输入的音量较小或音质较差(例如背景音较大)导致被识别为无效输入而误切换为手机自身听筒/麦克风模式通话时，本实施例可以通过比较手机自身听筒/麦克风模式和耳机模式下采集并处理得到的音频数据，确定最终通话模式并进行自动切换，避免由于背景音太嘈杂或者信号太差时导致的误切换。When the user is indeed using a peripheral headset to make a call, but due to the low volume of the voice input or poor sound quality (such as loud background sound), it is recognized as invalid input and is mistakenly switched to the phone's own handset/microphone The embodiment can determine the final call mode and perform automatic switching by comparing the audio data collected and processed in the handset/microphone mode of the mobile phone itself and the earphone mode to avoid false switching caused by too noisy background sound or poor signal.

当通过本发明实施例提供的方法切换通话模式后，手机提供文字或语音提示，提示用户手机通话模式已经切换，便于用户发现系统自动切换通话模式的行为，使用户能了解是否使用不当造成听不见声音。After the call mode is switched by the method provided by the embodiment of the present invention, the mobile phone provides a text or voice prompt to remind the user that the call mode of the mobile phone has been switched, which is convenient for the user to find the behavior of the system automatically switching the call mode, so that the user can know whether improper use causes inaudible sound.
