In addition, while functional block division is performed in a device diagram and logical order is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the block division in the device, or in the flowchart. Furthermore, the words "first," "second," "third," and the like as used herein do not limit the order of data and execution, but merely distinguish between identical or similar items that have substantially the same function and effect.
The method for multi-application voice acquisition provided by the embodiment of the application is suitable for the application scenario shown in fig. 1, wherein the application scenario is a multi-application voice acquisition system, and the multi-application voice acquisition system 100 comprises a pickup device 30, a second communication unit 13 and a second processing unit 14, and the second communication unit 13 is respectively connected with the pickup device 30 and the second processing unit 14. The second communication unit 13 and the second processing unit 14 are operated in the first terminal 10, and the first terminal device 10 is communicatively connected to the second terminal 20 and the sound pickup device 30, respectively.
The first terminal device 10 is provided with a first microphone 11 and a first loudspeaker 12, the second terminal device 20 is provided with a second microphone 21 and a second loudspeaker 22, and the first terminal device 10 is installed and operated with a first target application a and a translation application B, and the second terminal device 20 is installed and operated with a second target application D. The first target application a and the second target application D may be, for example, an instant messaging application, a social application, or the like. The first terminal 10 and the second terminal 20 may be, for example, terminal devices such as a smart phone, a tablet computer, a notebook computer, a desktop computer, and the like. The sound pickup apparatus may be, for example, a sound pickup.
Further, the first terminal 10 further includes a second communication unit 13 and a second processing unit 14, and the second communication unit 13 and the second processing unit 14 are communicatively connected. The sound pickup apparatus 30 includes a third microphone 31, a first processing unit 32, and a first communication unit 33, and the first processing unit 32 is connected to the third microphone and the first communication unit 33, respectively. The first processing unit 32 is configured to process the audio data, the first communication unit 33 is configured to send the processed audio data to the second communication unit 13, and the second communication unit 13 is configured to send the processed audio data to the second processing unit 14 for further processing, and then send the processed audio data to the translation application B through the interface.
The system is easy to understand, and a multi-application voice acquisition system will be described with reference to the accompanying drawings. As shown in fig. 1, the first user and the second user are internet users, the first user is a chinese, the second user is a foreigner, and the first user and the second user need to hold a video conference. The first user uses the first terminal 10 and the second user uses the second terminal 20. Since the first user and the second user use different voices, there may be a language barrier. Because the dialog's content of the speaking needs to be translated into the native language by means of the translation application B. But none of the popular conference systems on the market have this function.
The first user and the second user perform a conversation, the process in which the first user hears the second user, the second user performs voice input through the second microphone 21 of the second terminal 20, the second target application program D operated by the second terminal 20 collects audio data input by the second user through the second microphone 21, and then transmits the audio data to the first terminal 10 through the internet. The audio data is played by the first speaker 12 on the first terminal 10 when the first user is able to hear the voice content of the second user. But the first user and the second user have language barriers, so that the first user cannot understand the voice content of the second user.
In the above example, the second user hears the first user, and the first user inputs voice through the first microphone 11 of the first terminal 10, the first target application a running on the first terminal 10 collects audio data input by the first user through the first microphone 11, and the first target application a also collects audio data of the second user played through the first speaker 12, and when the first user and the second user repeatedly talk, the microphones and speakers on both sides repeatedly collect audio data and play, whereby howling noise occurs.
In order to avoid howling, the first microphone 11 is usually shielded from the sound collected from the first speaker 12 by an active noise reduction and cancellation technique, with opposite phases and a cancellation mechanism, so that the second user does not hear his own voice from the second microphone 21, thereby solving the howling noise. But the translation application B cannot collect audio data of the second user from the first microphone 11.
In order to solve the technical problem, the present application introduces a sound pickup apparatus 30, where the sound pickup apparatus 30 collects audio data played by the first speaker 12 through a third microphone 31, the audio data including ambient speech and audio speech, and then packetizes, encodes and compresses the audio data through a first processing unit 32 to obtain first audio data. The first audio data is then transmitted to the second communication unit 13 through the first communication unit 33, the second communication unit 13 sends the first audio data to the second processing unit 14 for decompression and decoding to obtain second audio data, and the second processing unit 14 transmits the second audio data to the translation application B through the interface, so that the translation application B translates the second audio data. Therefore, the translation application program can smoothly collect and translate the audio data by means of the audio transmission mode of the pickup device with low time delay.
It should be noted that, the method for multi-application voice acquisition provided by the embodiment of the present application may also be applied to other suitable application scenarios, and may also include more terminals in the actual application process.

And 220, processing the audio data to obtain first audio data.
Specifically, audio data is processed, firstly, the audio data is packetized by a first processing unit, then the audio data is encoded, and finally, the audio data is compressed, so that first audio data is obtained. It should be noted that, the first audio data and the second audio data below are defined for the purpose of illustrating the present application, and are relative concepts, not limiting the present application.
And 230, transmitting the first audio data to the first terminal, so that the first terminal performs secondary processing on the first audio data to obtain second audio data.
In the embodiment of the application, the first audio data is subjected to secondary processing, the first audio data is decompressed by the second processing unit, and then the first audio data is decoded, so that the second audio data is obtained. Specifically, the first communication unit of the pickup apparatus transmits first audio data to the first terminal, and the second processing unit of the first terminal decompresses and decodes the first audio data, thereby obtaining second audio data.
And step 240, sending the second audio data to a translation application program so that the translation application program translates the second audio data.
