FIG. 2 is a schematic diagram of a method for switching a call mode according to an embodiment of the present invention. As shown in Figure 2, the method includes:

Step 201: The first terminal connected to the peripheral earphone establishes a call connection with the remote device.

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 a headphone jack on the first terminal. When the peripheral earphone is a wireless earphone, the earphone 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.

The first terminal establishes a call connection with the remote device, where the first terminal may be the calling terminal or the called terminal.

Step 202: After the first terminal establishes a call connection with the remote device, the first terminal collects the first sound signal through the microphone of the peripheral earphone.

The peripheral headset includes a microphone and an earpiece. The microphone can be used to collect sounds emitted by the user or ambient sounds, and transmit the collected sounds to the first terminal. The handset 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.

After the first terminal establishes a call connection with the remote device, the first terminal collects the user's voice, that is, the first sound signal, through the microphone of the peripheral earphone. 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: at the first When the terminal calls the remote device as the calling terminal, and the call connection is not established, the microphone of the peripheral earphone can be used for collecting sound. At this time, if the voice of the user terminates the call, the first terminal can terminate the call. When the first terminal receives the call of the remote device as the called terminal, and the call connection is not established, the microphone of the peripheral earphone can also be used for collecting sound. At this time, if the voice of the user hangs up the call is collected, The first terminal can hang up the incoming call. If the user receives the voice of the incoming call, the first terminal can answer the incoming call. In addition, when the first terminal is in a standby state or other state in which no call is in progress, the microphone of the peripheral earphone can also be used to collect the voice of the user. For example, the user can perform voice control on the first terminal through the microphone of the peripheral earphone. The first terminal is controlled by voice to open an application or perform a certain function. That is to say, after detecting that the first terminal has established a connection with the peripheral earphone, the sound can be collected through the microphone of the peripheral earphone. Of course, the first terminal can also collect sound through the microphone of the peripheral earphone only after establishing a call connection with the remote device.

It should be noted that when the first terminal collects a 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.

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 the first audio data, and the first audio data may be an analog signal or a digital signal after the analog-to-digital conversion.

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, step 205 is performed, if it is determined that the first audio data is valid. Data, the first terminal continues to use the peripheral earphone to make a call, that is, the first terminal uses the headset mode to make a call, uses the microphone of the peripheral earphone to collect the external sound, and uses the earphone of the peripheral earphone to play the sound.

The first terminal may determine whether the audio data is valid data by any of the following manners.

Manner 1: The first terminal compares the audio data with the empirical data. If the audio data is determined to be valid by the comparison, if the audio data is determined to be valid data, the audio data is determined to be the background sound. Or ambient sound, then the audio data is determined to be non-valid data.

Manner 2: the first terminal identifies the specific content of the audio data, and if the content of the audio data is the statement that the user frequently says during the call, determining that the first audio data is valid data, and if the audio data cannot be recognized The content determines that the audio data is not valid data.

Manner 3: The first terminal acquires a voice similarity between the audio data and the experience data. If the voice similarity is greater than a preset threshold, determining that the audio data is valid data, if the voice similarity is less than or equal to the The preset threshold determines that the audio data is inactive data.

Step 205: The first terminal switches to collect a second sound signal by using a microphone of the first terminal. When the sound collected by the microphone of the peripheral earphone is an invalid sound, it means that the user may not currently use the earphone to make a call, but the first terminal is held and the first terminal's own microphone and earpiece are used. Therefore, the first terminal switches the headset mode to the normal mode, that is, switches to a mode in which the microphone of the first terminal itself and the handset are used for talking, and the external sound signal, that is, the second sound signal, is collected by the microphone of the first terminal itself. .

It should be noted that when the first terminal collects a sound signal through its own microphone, the first terminal can play the sound received from the remote device through its own earpiece.

After step 205, the method may further include step 206.

Step 206: The first terminal converts the collected second sound signal into second audio data. The process of converting a sound signal into audio data can be seen in step 203.

Step 207: The first terminal determines whether the second audio data is valid data; if it is determined that the second audio data is non-valid data, step 208 is performed; if it is determined that the second audio data is valid data, executing Step 210. For a method of determining whether the audio data is valid data, refer to the description in step 204.

Step 208: The first terminal compares the first audio data with the second audio data. If the voice quality of the first audio data is higher than the voice quality of the second audio data, step 209 is performed, if the first audio is used. The voice quality of the data is lower than the voice quality of the second audio data, and step 210 is performed.

Step 209: The first terminal switches to collect a sound signal through a microphone of the peripheral earphone.

When the quality of the sound signal collected by the microphone of the peripheral earphone is higher than the quality of the sound signal collected by the microphone of the first terminal itself, indicating that the current user is using the peripheral earphone for the call, the first terminal needs to be switched again. To talk to the peripheral headset mode, the external sound is collected through the microphone of the peripheral headset. It may be because the quality of the current call is not high, which leads to the misjudgment in step 204.

Step 210: The first terminal continues to use its own microphone and the handset to make a call, that is, the first terminal continues to use its own microphone to collect external sound, and uses its own earpiece to play the sound. When the quality of the sound signal collected by the microphone of the first terminal itself is higher than the quality of the sound signal collected by the microphone of the peripheral earphone, it indicates that the current user is not using the peripheral earphone. It may be because the quality of the current call is not high, which leads to the misjudgment in step 207.

The method embodiment may further include: the first terminal may prompt the user which call mode is currently in use. For example, when the first terminal detects that it is connected to the peripheral headset, the user may be prompted to be in the headset mode; when the first terminal switches from the headset mode to the normal mode, the user may be prompted to be in the normal mode or prompt the user. The mode has been switched; when the first terminal switches from the normal mode back to the headset mode, the user may be prompted again to the current mode or the user mode is prompted to be switched. When the user is prompted, the first terminal can make a text or graphic prompt through its own display screen, or make a voice prompt through the speaker or peripheral earphone of the first terminal.

In the embodiment of the present invention, after establishing a call connection with the remote device, the terminal connected to the peripheral device first uses the peripheral earphone to make a call, and determines 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 handset to make a call, that is, automatically switch the call mode. After the handover, if it is judged that the sound quality collected by the terminal's own microphone is lower than the sound quality collected by the microphone of the peripheral earphone, the terminal automatically switches back to the headset call mode, that is, switches back to use the peripheral earphone for the call. Therefore, the embodiment of the present invention can automatically switch the call mode and improve the convenience of the terminal. Moreover, the embodiment of the present invention can prompt the current call mode and the mode switching information to the user, so that the user can know the behavior of the terminal automatically switching the call mode.

The scheme of the embodiment of the present invention is specifically described below by taking the mobile phone as an example through the embodiments shown in FIG. 3 and FIG. 4 .

Specifically, as shown in FIG. 3, the method may include the following steps:

In 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 calling party, 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.

Step 302: The mobile phone determines whether it is connected to the peripheral earphone, including determining whether the earphone jack is occupied by the wired earphone (ie, determining whether the mobile phone and the wired earphone are connected) and/or determining whether the wireless earphone such as the mobile phone and the Bluetooth earphone is in If the mobile phone and the peripheral earphone are in a connected state, the process proceeds to step 303.

It should be noted that the embodiment of the present invention does not limit the execution order of step 302, or may not include step 302. After the wired headset is inserted into the mobile phone or the wireless headset is paired with the mobile phone, the mobile phone can know that the connection with the peripheral earphone is established. During the subsequent call, the mobile phone can select the headset mode, that is, after step 301, the mobile phone can enter the step. 303.

Step 303: The mobile phone collects an external sound through a microphone of the peripheral earphone.

Step 304: The mobile phone converts the collected sound signal into first audio data, and may 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 the memory of the mobile phone, which may be sent in real time or preset by system. A certain period of transmission (for example, every 10ms).

Step 305: The mobile phone determines whether the first audio data in the preset time period is valid data; if it is valid data, step 306 is performed, and if it is invalid data, step 307 is performed. The first audio data in the preset time period may be: the first audio data converted by the sound collected by the peripheral earphones in the preset time period.

For example, the processor or audio circuitry of the handset determines whether the first audio data is valid data. When judged by the audio circuit, the audio circuit can transmit the determination result to the processor. The preset time period may be the first time period of the call establishment, for example, the first one second, two seconds, three seconds, or five seconds after the call is established, and the length of the specific time is not limited.

The mobile phone determines whether the audio data is valid data by any one or several of the following methods:

Method 1: Compare the recognition result with the empirical data (which can be a database of experts, a smart library, an experience database, etc., which stores a large number of vocals), and determine whether the audio data is vocal (effective data) or background sound or Ambient sound (invalid data); the identification may be speech recognition or semantic recognition, or other algorithms for audio data, as long as the audio data can be compared with empirical data.

Method 2: Identify the specific content of the audio data, and judge whether it is valid data according to the specific content. For example, if the content of the recognized audio data is “Hello”, “Who are you”, “Hey”, “Speak”, “No Sound”, “I am Tom”, etc. 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 identified, it can be judged as valid data; if it is not recognized, it is judged as invalid data.

Manner 3: By comparing the recognition result with the empirical data to obtain the similarity degree of the speech, determining whether the speech similarity exceeds a preset speech similarity threshold, and if the threshold is exceeded, determining that the data is valid, and if the threshold is not exceeded, the determination is invalid. data.

Step 306: The mobile phone keeps the current call mode as the headset mode.

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. At the time of switching or after switching, the mobile phone can prompt the user that the call mode has been switched.

Step 308: The mobile phone adopts the handset/microphone mode of the mobile phone itself, that is, the mobile phone uses its own earpiece and microphone to make a call.

When the user's mobile phone is connected to the peripheral headset, but the user does not know the current connection status while using the mobile phone to make a call without using the headset, the mobile phone will automatically determine which call mode to use according to the actual situation to prevent misconnection. Turn off the phone. And, the phone can automatically switch the call through the phone's own audio circuit and processor. The mode eliminates the user's manual steps and solves the problem of accidentally hanging up the phone without adding additional hardware.

In some uncommon situations, the user does use a peripheral headset to make a call, but because the collected sound signal is poor (far from the base station or the background noise is too large), the sound signal may be recognized as an invalid input. It was mistakenly switched to use the handset's own handset/microphone mode to talk. In order to further solve the problem, the embodiment may further determine the final call mode and perform automatic switching by comparing the sounds collected by the handset's own handset/microphone mode and the headset mode 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 performed step 307, that is, the mobile phone has switched to the handset's own handset/microphone mode, and thereafter, as shown in FIG. 4, may also include The following steps:

Step 401: The mobile phone starts to collect the sound signal by using its own microphone. For example, the processor of the mobile phone notifies the handset's own microphone to start collecting external sound, and notifies the audio circuit to start receiving and processing the sound signal collected by the microphone.

Step 402: The mobile phone converts the sound signal collected in step 401 into second audio data.

Step 403: The mobile phone determines whether the second audio data in the preset time period is valid data; if it is valid data, step 404 is performed, and if it is invalid data, step 405 is performed. The preset time period may be a period of time after the call mode is switched, for example, to switch to the first one second, two seconds, three seconds, or five seconds after the voice is collected by the mobile phone's own microphone, and the length of the specific time is not limited. The length of the preset time period may be the same as or different from that in step 305. For the method for determining whether the second audio data is valid data by the mobile phone, refer to the foregoing method for determining whether the first audio data is valid data.

Step 404: The mobile phone keeps the current call mode as its own handset/microphone mode.

Step 405: The mobile phone acquires the first audio data in the headset mode and the second audio data in the handset's own handset/microphone mode; specifically, the following two methods are available:

Manner 1: The mobile phone acquires the second audio data currently processed, and acquires the first audio data in the previously stored headset mode from the memory of the mobile phone;

Manner 2: The mobile phone acquires the first audio data and the second audio data from a memory, wherein the second audio data is stored in the memory of the mobile phone by the mobile phone in step 402.

Step 406: The mobile phone compares the voice quality of the first audio data and the second audio data. For example, whether the voice quality of the first audio data is higher than the first is determined by comparing key factors such as volume, resolution, and the like of the voice. The voice quality of the second audio data, if not, proceed to step 404, and if so, when the handset itself receives the microphone When the received voice quality is lower than the voice quality received by the headset, the process proceeds to step 407.

Step 407: The mobile phone switches the call mode to the headset mode.

When the user does use a peripheral headset to make a call, but because the volume of the voice input is small or the sound quality is poor (such as a large background sound), it is recognized as an invalid input and is mistakenly switched to the handset's own handset/microphone mode call. The embodiment can determine the final call mode and automatically switch by comparing the audio data collected and processed by the handset's own handset/microphone mode and the headset mode, to avoid false switching caused by the background sound being too noisy or the signal being too poor.

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 prompt the user that the mobile phone call mode has been switched, so that the user can find that the system automatically switches the call mode, so that the user can understand whether the use is improper or not. sound.
