Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for multi-terminal voice communication, which is applied to terminal equipment, and the specific application scene of the method provided by the embodiment of the invention can be as follows: multi-player voice chat, multi-player conference calls, multi-player game voice calls, etc. In the embodiment of the invention, the acquisition timestamp corresponding to the voice data is carried in the transmitted voice data, and the voice data is compared with the voice data acquired by the terminal equipment, so that the received voice data is determined to be discarded or played in a non-external mode.
Fig. 2 is a flowchart of a first method of a multi-terminal voice call method according to an embodiment of the present invention, where the method is applied to a first terminal device, and the method shown in fig. 2 at least includes the following steps:
s102, after receiving first voice data sent by opposite terminal equipment, first terminal equipment detects whether the opposite terminal equipment belongs to second terminal equipment; the first voice data carries a collection time stamp of the first voice data; the second terminal device and the first terminal device meet preset conditions, the preset conditions comprise that the spacing distance is smaller than or equal to a preset distance, and the loudspeaker is in an on state.
The second terminal device is a terminal device which performs voice communication with the first terminal device, and the speaker being in the on state means that the speakers of the first terminal device and the second terminal device are both in the on state.
The execution main body of the method provided by the embodiment of the invention is the first terminal equipment, wherein the first terminal equipment is any one terminal equipment in a plurality of terminal equipment for carrying out voice communication. For example, in a single multi-terminal voice call, the terminals performing the voice call are respectively denoted as terminal a, terminal B, terminal C, and terminal D, and the first terminal may be any one of terminal a, terminal B, terminal C, and terminal D.
The peer device refers to other terminal devices except the first terminal device among the plurality of terminal devices performing the voice call. Continuing with the above example, in the above example, if the first terminal device is terminal device a, the opposite terminal devices are terminal device B, terminal device C, and terminal device D.
When the method provided by the embodiment of the invention is adopted to carry out multi-terminal voice call, firstly, communication connection needs to be established for a plurality of terminal devices carrying out voice call, and in the process of establishing communication connection, each terminal device is triggered to report the current geographical position information to the server.
The server refers to a server corresponding to an application program used when a plurality of terminal devices realize voice communication. For example, if the multi-terminal device performs a voice call through the first instant messaging software, the server is a server corresponding to the first instant messaging software; if the multi-terminal equipment establishes the voice call in a certain game, the server is the server corresponding to the game.
After the plurality of terminal devices establish communication connection, each terminal device starts to collect voice data of a user corresponding to the terminal device, and sends the collected voice data to other terminal devices for voice communication through a network.
In this embodiment of the present invention, in step S102, it is detected whether the peer device belongs to the second terminal device, and it is determined whether the peer device belongs to the second terminal device by detecting whether a separation distance between the first terminal device and the peer device is smaller than or equal to a preset distance and whether a speaker of the peer device is in an on state.
Or, in another specific embodiment, after the communication connections of the plurality of terminal devices are established, the second terminal device list corresponding to the first terminal device is determined from the plurality of terminal devices. Correspondingly, in step S102, detecting whether the peer device belongs to a second terminal device includes: and detecting whether the opposite terminal equipment exists in the second terminal equipment list.
In the embodiment of the present invention, if the peer device exists in the second terminal device list, it indicates that the peer device that sends the first voice data to the first terminal device belongs to the second terminal device; if the opposite terminal device does not exist in the second terminal device list, it indicates that the opposite terminal device sending the first voice data to the first terminal device does not belong to the second terminal device.
The first voice data received by the first terminal device carries the identifier of the opposite terminal device, so that the opposite terminal device can be searched in the second terminal device list through the identifier of the opposite terminal device. The identifier of the terminal device may be an Identification (ID) of the terminal device, and the like.
The terminal devices stored in the second terminal device list and the first terminal device satisfy the preset condition, that is, the terminal devices stored in the second terminal device list are devices that may generate voice interference to the first device.
In the embodiment of the present invention, the server may determine the second terminal device list, or the first terminal device may determine the second terminal device list.
The preset distance generally refers to a maximum distance that may cause voice interference between two terminal devices, and a specific value may be 5 meters, 3 meters, and the like.
For example, in a multi-terminal voice call, terminal devices that perform voice calls are marked as a terminal device a, a terminal device B, a terminal device C, and a terminal device D, and speakers of the terminal device a, the terminal device B, the terminal device C, and the terminal device D are all in an on state; distances between the terminal device A and the terminal devices B and C are 3 meters, distances between the terminal device B and the terminal device C are 2 meters, and distances between the terminal device D and the terminal device A and between the terminal device B and the terminal device C are more than one hundred meters, so that the terminal device A, the terminal device B and the terminal device C can be determined to be interference devices possibly mutually, namely, a second terminal device list corresponding to the terminal device A is the terminal device B and the terminal device C, a second terminal device list corresponding to the terminal device B is the terminal device A and the terminal device C, a second terminal device list corresponding to the terminal device C is the terminal device A and the terminal device B, and the terminal device D does not have corresponding interference devices.
The preset distance may be set empirically, and may be determined as follows:
the server controls a plurality of terminal devices which carry out voice communication to sequentially send detection voices with the same content to other terminal devices according to a certain time interval, after each terminal device receives the detection voices, the received detection voices are played through the loudspeaker, and then the preset distance is determined according to the signal amplitude of the detection voices played by the loudspeaker and collected by each terminal device.
For example, in a multi-terminal voice call, terminal devices performing the voice call are respectively marked as a terminal device a, a terminal device B and a terminal device C, a server firstly controls the terminal device a to send a detection voice, the detection voice carries a collection timestamp of the detection voice, after the terminal device B and the terminal device C receive the detection voice which is sent by the terminal device a and carries timestamp information, the detection voice is played through a loudspeaker, if the distance between the terminal device a, the terminal device B and the terminal device C is short, microphones (microphones, MICs) of the terminal device a, the terminal device B and the terminal device C collect the detection voice played by the terminal device B and the terminal device C through the loudspeaker, and then each terminal device determines the volume signal amplitude of the collected detection voice; after receiving the detection voice sent by the terminal device A, the terminal device B sends a detection voice with timestamp information to the terminal device A and the terminal device B, after receiving the detection voice, the terminal device A and the terminal device B play the detection voice through a loudspeaker, if the distances among the terminal device A, the terminal device B and the terminal device C are short, MICs of the terminal device A, the terminal device B and the terminal device C all collect the detection voice played by the terminal device A and the terminal device C through the loudspeaker, and then each terminal device determines the volume signal amplitude of the detection voice collected by each terminal device; similarly, after receiving the detection voice sent by the terminal device B, the terminal device C sends voice data carrying timestamp information to the terminal device a and the terminal device B, when the terminal device B and the terminal device a receive the detection voice carrying timestamp information sent by the terminal device C, the detection voice is played through a loudspeaker, if the distances among the terminal device a, the terminal device B and the terminal device C are short, MIC of the terminal device a, MIC of the terminal device B and MIC of the terminal device C all collect the detection voice played by the terminal device C and MIC of the terminal device a through the loudspeaker, and then each terminal device determines the volume signal amplitude of the detection voice collected by each terminal device; the server compares the volume signal amplitude of the detected voice collected by each terminal device with a preset threshold value, if the volume signal amplitude collected by the terminal device is larger than the preset threshold value, the server indicates that the terminal device can collect the detected voice played by other devices through a loudspeaker, and can determine that two terminal devices can generate interference under the current distance.
In the embodiment of the invention, the preset distance is determined by controlling each terminal device to send out the detection voice, so that the determined preset distance is more consistent with the distance causing howling, and the accuracy is higher.
In the embodiment of the present invention, if the preset distance is determined by sending the detection voice, under the condition that there are many terminal devices performing voice communication, each terminal device needs to send the detection voice once to the outside, and each terminal device needs to collect the detection voice many times, and the operation is complex, so that in order to reduce the operation complexity and also consider the accuracy of the determination result, in the embodiment of the present invention, the terminal devices located in the preset range around each terminal device may be determined by the geographical location information of each terminal device, and then the preset distance is determined by sending the detection voice to the outside.
In the embodiment of the present invention, if the first terminal device determines the preset distance, the method specifically includes the following steps:
the method comprises the steps that a first terminal device determines terminal devices located in a preset range around the first terminal device from a plurality of terminal devices in voice communication with the first terminal device; the method comprises the steps that a first terminal device obtains the volume signal amplitude of detected voice collected by the first terminal device; the detection voice is played through the first terminal equipment and speakers of the terminal equipment located in a preset range around the first terminal equipment; and the first terminal equipment determines the preset distance according to the volume signal amplitude and a preset threshold value.
In the implementation mode, the first terminal device determines the terminal devices located in the peripheral preset range according to the geographical position information of each terminal device, then the first terminal device and the terminal devices located in the peripheral preset range of the first terminal device sequentially send detection voices outwards according to a certain time interval, after each terminal device receives the detection voices, the detection voices are played through a loudspeaker, then the first terminal device and other terminal devices collect the detection voices, and the first terminal device determines the corresponding interference devices from the terminal devices located in the peripheral preset range according to the collected detection voices. Therefore, the voice detection measurement process can be simplified, and the determined preset distance is high in accuracy.
S104, if the opposite terminal device belongs to the second terminal device, the first terminal device controls a loudspeaker of the first terminal device to be closed or discards the first voice data according to the acquisition timestamp, the first voice data and the stored voice data; the stored voice data is voice data collected by the first terminal device within a preset time period.
The stored voice data stores the corresponding relation between the voice data acquired by the first terminal device and the acquisition 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 it has collected and also stores a collection time stamp for the voice data.
In step S104, the first terminal device controls a speaker of the first terminal device to close or discard the first voice data according to the collecting timestamp, the first voice data, and the stored voice data, and specifically includes:
the first terminal equipment detects whether the voice data which is acquired at the moment corresponding to the acquisition timestamp and is matched with the first voice data exists in the stored voice data; and if so, controlling a loudspeaker of the first terminal device to be closed or discarding the first voice data.
When the first terminal equipment receives the first voice data sent by the second terminal equipment, the voice data is demodulated and decoded to obtain the acquisition time stamp and the voice content corresponding to the first voice data, then the first terminal equipment matches the received first voice data with each voice data in the stored voice data, and determines whether the stored voice data has the voice data which has the same acquisition time stamp corresponding to the first voice data and the same voice content with the first voice data, if so, the first voice data sent by the second terminal device is the collected voice data when the user of the first terminal device speaks, at this time, in order to avoid playing the speaking content of the corresponding user of the first terminal device, or to avoid the occurrence of sound superposition with the same phase, the first terminal device discards the first voice data or controls a speaker of the first terminal device to be turned off.
In the embodiment of the present invention, the speaker of the first terminal device is controlled to be turned off, so that the first voice data is not actually played through the speaker, thereby avoiding the situation of overlapping sounds with the same phase, and avoiding howling.
The discarding of the first voice data may be deleting the first voice data.
In the embodiment of the invention, by discarding the first voice data consistent with the voice data of the voice list terminal stored by the first terminal device or controlling the loudspeaker of the first terminal device to be closed, the first terminal device can be prevented from playing the voice content of the first terminal device corresponding to the user and collected by the opposite terminal device, the situations that the voice call content of multiple terminals is disordered and the sounds with the same phase are superposed are avoided, and the howling caused by the situation can be eliminated.
The method provided by the embodiment of the present invention includes, in addition to the case that the above-described peer device that sends the first voice data to the first terminal device belongs to the second terminal device, the case that the above-described peer device does not belong to the second terminal device, and specifically includes the following steps (a), (b), and (c);
(a) if the opposite terminal device does not belong to the second terminal device, the first terminal device detects whether the first voice data includes sub-voice data simultaneously sent by a plurality of opposite terminal devices.
Because the voice data sent by each peer device carries the identifier of the peer device, the first terminal device can determine whether the first voice data includes sub-voice data sent by multiple peer devices at the same time through the number of identifiers of the peer devices carried in the received first voice data.
And recording the voice data sent by the opposite terminal equipment as sub-voice data.
(b) If the first voice data includes sub-voice data sent by multiple peer devices at the same time, the first terminal device detects whether at least two peer devices meeting the preset condition exist in the multiple peer devices.
Wherein the preset conditions are as follows: the spacing distance between the opposite terminal devices is smaller than or equal to the preset distance, and the loudspeaker is in an open state.
(c) If at least two opposite-end devices meeting the preset condition exist in the plurality of opposite-end devices, the first terminal device detects whether sub-voice data corresponding to the at least two opposite-end devices are repeated sub-voice data; wherein, the repeated sub-voice data refers to the same collecting time stamp and the sub-voice data are consistent; if yes, the first terminal device plays one of the repeated sub-voice data.
In addition, in the embodiment of the present invention, if there are no at least two peer devices that satisfy the preset condition in the multiple peer devices, the first terminal device may directly play the sub voice data in the first voice data.
In the embodiment of the present invention, the at least two peer devices meeting the preset condition may be peer devices that generate mutual voice interference, and if the sub-voice data sent by the at least two peer devices meeting the preset condition is repeated sub-voice data, it indicates that the at least two peer devices meeting the preset condition collect the speech content that may be of the same user.
In the embodiment of the invention, only one sub voice in the repeated sub voice data is played for the sub voice data determined to be repeated, so that the repeated playing is avoided, and the problems of playing sound confusion and the like caused by simultaneously playing a plurality of same sub voice data are avoided.
To describe the above process in detail, the following will exemplify the above process. Fig. 3 shows a schematic diagram of an online call of multiple terminal devices in an embodiment of the present invention, in the case shown in fig. 3, a terminal device performing a voice call includes a terminal device a, a terminal device B, a terminal device C, a terminal device D, and a terminal device E, where the terminal device a and the terminal device B satisfy the preset condition, the terminal device C and the terminal device D satisfy the preset condition, that is, there may be mutual interference devices between the terminal device a and the terminal device B, there may be mutual interference devices between the terminal device C and the terminal device D, and neither the terminal device E interferes with the any one of the devices.
