The specific application scenarios of the method provided by the embodiment of the present invention may be: multi-person voice chat, multi-person conference call, multi-person game voice calls etc. In the embodiment of the present invention, by carrying the collection time stamp corresponding to the voice data in the transmitted voice data, and comparing the voice data with the voice data collected by the terminal device itself, it is determined that the received voice The data is discarded or played in a non-external format, so as to avoid playing the speech content of the corresponding user collected by the peer device, thereby avoiding the confusion of multi-terminal voice call content and the superimposition of sounds with the same phase , so that howling can be eliminated.

FIG. 2 is a flow chart of the first method of the multi-terminal voice call method provided by the embodiment of the present invention. The method is applied to the first terminal device. The method shown in FIG. 2 includes at least the following steps:

S102. After receiving the first voice data sent by the peer device, the first terminal device detects whether the peer device belongs to the second terminal device; wherein, the above-mentioned first voice data carries a collection time stamp of the first voice data; the second The second terminal device and the first terminal device meet a preset condition, and the preset condition includes that the separation distance is less than or equal to the preset distance, and the speaker is turned on.

Wherein, the above-mentioned second terminal device is a terminal device that conducts a voice call with the first terminal device, and the above-mentioned loudspeaker being in an on state means that both the speakers of the first terminal device and the second terminal device are in an on state.

The execution subject of the method provided by the embodiment of the present invention is the first terminal device, where the first terminal device is any terminal device among multiple terminal devices that conduct voice calls. For example, in a multi-terminal device voice call, the terminal devices conducting the voice call are respectively recorded as terminal device A, terminal device B, terminal device C and terminal device D, then the above-mentioned first terminal device may be terminal device A, terminal device B. Any one of terminal equipment C and terminal equipment D.

The aforementioned peer device refers to other terminal devices except the first terminal device among the plurality of terminal devices conducting voice calls. Continuing to use the above example, in the above example, if the first terminal device is terminal device A, then the peer devices are terminal device B, terminal device C, and terminal device D.

When using the method provided by the embodiment of the present invention to conduct a multi-terminal voice call, it is first necessary to establish a communication connection for multiple terminal devices conducting a voice call, and, in the process of establishing a communication connection, trigger each terminal device to connect to the The geographic location information is reported to the server.

Wherein, the above-mentioned server refers to a server corresponding to an application program used by multiple terminal devices to implement a voice call. For example, if the multi-terminal devices make a voice call through the first instant messaging software, the above-mentioned server is the server corresponding to the first instant messaging software; if the multi-terminal device establishes a voice call in a certain game, then the above-mentioned server is the The server corresponding to the game.

After multiple terminal devices establish a communication connection, each terminal device starts to collect voice data of its corresponding user, and sends the collected voice data to other terminal devices conducting voice calls through the network.

In the embodiment of the present invention, in the above step S102, the detection of whether the peer device belongs to the second terminal device can be performed by detecting whether the distance between the first terminal device and the peer device is less than or equal to the preset distance, and Whether the speaker of the end device is turned on determines whether the peer device belongs to the second terminal device.

Or, in another specific implementation manner, after the communication connections of the multiple terminal devices are established, the second terminal device list corresponding to the first terminal device is determined from the multiple terminal devices. Correspondingly, in the above step S102, detecting whether the peer device belongs to the second terminal device includes: detecting whether the peer device exists in the second terminal device list.

In the embodiment of the present invention, if the above-mentioned peer device exists in the second terminal device list, it means that the peer device that sends the first voice data to the first terminal device belongs to the second terminal device; if the above-mentioned second terminal device If the peer device does not exist in the list, it means that the peer device sending the first voice data to the first terminal device does not belong to the second terminal device.

Wherein, the first voice data received by the first terminal device carries the identifier of the peer device, so that the peer device can be searched in the second terminal device list through the identifier of the peer device. The identifier of the terminal device may be a code (identification, ID) of the terminal device or the like.

Wherein, each terminal device stored in the second terminal device list meets the above preset condition with the first terminal device, that is, each terminal device stored in the second terminal device list is a device that may cause voice interference to the first device .

In this embodiment of the present invention, the above-mentioned second terminal device list may be determined by the server, or the second terminal device list may be determined by the first terminal device.

Wherein, the aforementioned preset distance generally refers to a maximum distance between two terminal devices that may cause voice interference, and a specific value may be 5 meters, 3 meters, etc.

For example, in a multi-terminal voice call, the terminal devices conducting the voice call are recorded as terminal device A, terminal device B, terminal device C and terminal device D, and the terminal device A, terminal device B, terminal device C and terminal device D are The speakers are all on; the distance between terminal A, terminal B and terminal C is 3 meters, the distance between terminal B and terminal C is 2 meters, and the distance between terminal D and terminal A, terminal The distance between device B and terminal device C is more than 100 meters. Therefore, it can be determined that terminal device A, terminal device B, and terminal device C may be mutually interfering devices, that is, the second terminal device list corresponding to terminal device A is terminal Device B and terminal device C, the second terminal device list corresponding to terminal device B is terminal device A and terminal device C, the second terminal device list corresponding to terminal device C is terminal device A and terminal device B, and terminal device D does not exist Corresponding interference device.

Wherein, the above preset distance can be set according to experience, and can also be determined in the following way:

The server controls multiple terminal devices making voice calls to send detection voices with the same content to other terminal devices sequentially at a certain time interval. When each terminal device receives the detection voice, it plays the received detection voice through the speaker, and then according to The signal amplitude of the detected voice played by the loudspeaker collected by each terminal device determines the preset distance.

For example, in a multi-terminal voice call, the terminal devices conducting the voice call are respectively recorded as terminal device A, terminal device B, and terminal device C, and the server first controls terminal device A to send a detection voice, which carries the The time stamp of the detection voice is collected. When terminal device B and terminal device C receive the detection voice with time stamp information sent by terminal device A, they will play the detection voice through the speaker. If terminal device A, terminal device B and terminal device When the distance between C is relatively short, the microphones (microphone, MIC) of terminal equipment A, terminal equipment B, and terminal equipment C all collect the detection voices played by terminal equipment B and terminal equipment C through the speakers, and then each terminal equipment determines its collection The volume signal amplitude of the detection voice; when terminal device B receives the detection voice sent by terminal device A, it sends a detection voice with time stamp information to terminal device A and terminal device B, when terminal device A and terminal device B After receiving the detection voice, the detection voice is played through the speaker. If the distance between terminal device A, terminal device B and terminal device C is relatively short, the MICs of terminal device A, terminal device B and terminal device C all collect terminal Device A and terminal device C play the detected voice through the speaker, and then each terminal device determines the volume signal amplitude of the detected voice collected by it; similarly, after terminal device C receives the detected voice sent by terminal device B, it sends Send voice data with time stamp information with terminal device B, when terminal device B and terminal device A receive the detection voice with time stamp information sent by terminal device C, play the detection voice through the speaker, if terminal device A , when the distance between terminal device B and terminal device C is relatively short, the MICs of terminal device A, terminal device B, and terminal device C all collect the detection voice played by terminal device C and terminal device A through the speakers, and then each terminal device determines The volume signal amplitude of the detected voice collected by it; the server compares the volume signal amplitude of the detected voice collected by each terminal device with the preset threshold value. If the volume signal amplitude collected by the terminal device is greater than the preset threshold value, it means The terminal device can collect the detection voice played by other devices through the speaker, and can determine that the two terminal devices can interfere at the current distance. Through the above voice test, the distance between the two terminal devices that can cause interference can be determined. The distance is determined as the aforementioned preset distance.

In the embodiment of the present invention, the aforementioned preset distance is determined by controlling each terminal device to send out the detection voice, so that the determined preset distance is more in line with the distance causing howling, and the accuracy is higher.

In the embodiment of the present invention, if the above-mentioned preset distance is determined by sending detection voice, in the case of many terminal devices making voice calls, it is necessary for each terminal device to send out a detection voice once, and each The terminal devices need to collect multiple detection voices, and the operation is relatively complicated. Therefore, in order to reduce the operation complexity and take into account the accuracy of the determination results, in the embodiment of the present invention, it is also possible to first determine the location information of each terminal device. The terminal devices located within a preset range around each terminal device then determine the preset distance by sending out detection voices.

In the embodiment of the present invention, if the above-mentioned preset distance is determined by the first terminal device, it specifically includes the following steps:

The first terminal device determines a terminal device located within a preset range around it from a plurality of terminal devices with which it conducts a voice call; the first terminal device obtains the volume signal amplitude of the detected voice collected by it; wherein, the detected voice is passed through the first The terminal device and the voice played by the speaker of the terminal device within the preset range around the first terminal device; the first terminal device determines the preset distance according to the volume signal amplitude and the preset threshold.

In this embodiment, the first terminal device first determines the terminal devices located within the preset range around it according to the geographic location information of each terminal device, and then the first terminal device and the terminal devices located within the preset range around the first terminal device The terminal device sends out the detection voice in sequence according to a certain time interval. When the above-mentioned terminal devices receive the detection voice, they play the detection voice through the speaker, and then the first terminal device and other terminal devices collect the detection voice. The first terminal device The corresponding interference device is determined from the terminal devices located within the preset range around it according to the collected detection voice. In this way, the voice detection and measurement process can be simplified, and the determined preset distance is more accurate.

S104. If the peer device belongs to the second terminal device, the first terminal device controls the speaker of the first terminal device to turn off or discard the first voice data according to the above-mentioned collected time stamp, first voice data, and stored voice data; wherein, The voice data stored above is voice data collected by the first terminal device within a preset time period.

Wherein, the voice data stored above stores a corresponding relationship between the voice data collected by the first terminal device and the collection time stamp corresponding to the voice data. That is, each time the user of the first terminal device speaks, the first terminal device stores the voice data collected by it, and also stores the collection time stamp of the voice data.

In step S104, the first terminal device controls the speaker of the first terminal device to turn off or discard the first voice data according to the above-mentioned collected time stamp, first voice data and stored voice data, specifically including:

If the voice data with the same voice content exists, it means that the first voice data sent by the second terminal device is the voice data collected when the user of the first terminal device speaks. At this time, in order to avoid playing the corresponding user’s speech content, or in order to avoid superposition of sounds with the same phase, the first terminal device discards the first voice data or controls the speaker of the first terminal device to turn off.

In the embodiment of the present invention, controlling the loudspeaker of the first terminal device to turn off actually means that the above-mentioned first voice data is not played through the loudspeaker. In this way, the superposition of sounds with the same phase can be avoided, and howling can be avoided.

Wherein, the foregoing discarding of the first voice data may be deleting the first voice data.

In the embodiment of the present invention, by discarding the first voice data that is consistent with the voice data of the voice list terminal stored by the first terminal device or controlling the speaker of the first terminal device to be turned off, the first terminal device can be prevented from playing the voice of the peer device. The collected first terminal device corresponds to the voice content spoken by the user, which avoids the confusion of multi-terminal voice call content and the occurrence of superposition of sounds with the same phase, so that the resulting howling can be eliminated.

Wherein, the aforementioned preset condition is: the distance between the peer devices is less than or equal to the preset distance, and the speaker is turned on.

(c) If there are at least two peer devices that meet the preset conditions among the plurality of peer devices, the first terminal device detects whether the sub-voice data corresponding to the at least two peer devices is repeated sub-voice data ; Wherein, the above-mentioned repeated sub-voice data means that the collection time stamps are the same, and the sub-voice data are consistent; if so, the above-mentioned first terminal device plays one of the above-mentioned repeated sub-voice data.

In addition, in the embodiment of the present invention, if there are no at least two peer devices that meet the above preset conditions among the multiple peer devices, the first terminal device can directly play the sub-voice data in the above-mentioned first voice data. .

In the embodiment of the present invention, the above-mentioned at least two peer devices that meet the preset conditions may be peer devices that cause voice interference to each other. If the sub-voice data sent by the above-mentioned at least two peer devices that meet the preset conditions is Repeated sub-speech data means that at least two peer devices that meet the preset conditions may be the speech content of the same user. At this time, in order to avoid repeated playback and sound confusion caused by simultaneous playback, the first terminal device Only one sub-speech data among the repeated sub-speech data may be played.

In the embodiment of the present invention, for the repeated sub-voice data, only one sub-voice in the repeated sub-voice data can be played. In this way, repeated playback is avoided, and simultaneous playback of multiple identical sub-voices is avoided. Problems such as confusion of playback sound caused by data.
