[0027] The audio processing method provided by the present application can be configured in a computer device, which can be a central control system configured in a vehicle entertainment system. Figure 1 is a flowchart of the audio processing method provided by the present application. As shown in Figure 1 the method comprises the following steps S100-S130.

[0028] S100, calculate the target audio length that can be recognized by a target recognition system, and confirm the to-be-processed audio length according to the target audio length.

[0029] In the present application, the recognition system refers to a system for recognizing voice carried by the vehicle entertainment system, which can be the vehicle entertainment system itself or an algorithm in the vehicle entertainment system. The audio length of different recognition systems is different, and different vehicle models are often configured with different recognition systems. The target recognition system is the recognition system of the current vehicle model. It should be noted that the audio length of human voice is usually much longer than the audio length that can be recognized by the recognition system.

[0030] The audio in the vehicle is often of various types, such as ambient sound, sound of machine operation, or sound of conversation of passengers in the vehicle. The vehicle entertainment system acquires all the sound in real time, processes the acquired sound, and sends the processed audio to a corresponding recognition system. The recognition system identifies all the audio and extracts a control instruction, which is then returned to the vehicle entertainment system for execution of the control instruction. The target audio length is the length of audio that can be identified by the target recognition system. The length of audio acquired by the vehicle entertainment system is often greater than the target audio length, and thus cannot be directly identified by the target recognition system. Therefore, after the target audio length is determined, the length of audio to be processed needs to be confirmed. The length of audio to be processed is not necessarily the same as the target audio length, but the length of audio to be processed and the target audio length have certain commonalities. For example, if the target audio length is 2048, the length of audio to be processed can be 5120. 2048 and 5120 have multiple common divisors, and an intermediate audio length that conforms to the common divisors can be set to process the length of audio to be processed, so that the length of audio to be processed can be identified by the target audio length. It should be noted that the shortest audio length that can be supported by different vehicle entertainment systems is different, and the shortest audio length is often much greater than the target audio length. Therefore, the length of audio to be processed cannot be set to be the same as the target audio length.

[0031] In some embodiments, such as the present embodiment, the step of calculating the target audio length that can be identified by the target recognition system includes the steps of: confirming the number of audio channels, and calculating the target audio length according to the number of audio channels.

[0032] In the embodiments of the present application, the specific calculation method of the target audio length of the target recognition system can be to confirm the number of audio channels according to the number of audio zones, and then calculate the target audio length according to the number of audio channels. For example, for a vehicle model with two audio zones, it contains four channels, which are left mic, right mic, left ref, and right ref, and the target audio length is 256*4*2=2048. For a vehicle model with four audio zones, it contains six channels, which are left mic, right mic, left rear mic, right rear mic, left ref, and right ref, and the target audio length is 256*6*2=4096.

[0033] In some embodiments, such as the present embodiment, the step of confirming the length of audio to be processed according to the target audio length can include the steps of: judging the size of the target audio length and the shortest audio length that can be supported by the vehicle entertainment system; if the target audio length is less than the shortest audio length, creating a standard audio length according to a preset rule; and obtaining a data set of the audio to be identified according to the standard audio length to obtain the length of audio to be processed.

[0034] In the embodiments of the present application, generally, the shortest audio length supported by the in-vehicle entertainment system is longer than the target audio length, and in special cases, the shortest audio length supported by the in-vehicle entertainment system is shorter than the target audio length, in which case, the to-be-processed audio length can be directly set to be equal to the target audio length. If the shortest audio length supported by the in-vehicle entertainment system is longer than the target audio length, a standard audio length can be created according to a preset rule, which can be a plurality of values preset in advance according to experience, such as a first value and a second value, and the value higher than and closest to the shortest audio length is taken as the standard audio length. After the standard audio length is confirmed, a data set can be obtained from the to-be-identified audio to obtain the to-be-processed audio length. The to-be-identified audio refers to all the audio obtained by the in-vehicle entertainment system, and the to-be-processed audio length is equal to the standard audio length, the difference being that the to-be-processed audio length is obtained from the to-be-identified audio.

[0035] S110, a plurality of storage containers adapted to the target audio length and the to-be-processed audio length are created according to the target audio length and the to-be-processed audio length, and all the storage containers are stored in a buffer.

[0036] In the embodiments of the present application, the to-be-processed audio length is generally greater than the target audio length, for example, the to-be-processed audio length is 5120 and the target audio length is 2048, then a storage container with a data set length adapted to the to-be-processed audio length and the target audio length can be created, and the data set length can be found from the greatest common divisor of 5120 and 2048, the greatest common divisor of 5120 and 2048 being 2, 4, 10, …, 1024, and the greatest common divisor of 5120 and 2048 can be taken as the length of the storage container, i.e. 1024. The number of storage containers depends on the to-be-processed audio length, if the to-be-processed audio length is 5120 and the length of the storage container is 1024, then the number of storage containers is 5, and all the storage containers are stored in a buffer for easy reading. The buffer can be a ring buffer for storing data.

[0037] In some embodiments, such as the present embodiment, the step S110 can include the following steps: confirming the greatest common divisor of the target audio length and the to-be-processed audio length; creating the storage container according to the value corresponding to the greatest common divisor, and confirming the number of storage containers according to the multiple relationship between the to-be-processed audio length and the greatest common divisor.

[0038] In the embodiment of the present application, the greatest common divisor of the target audio length and the to-be-processed audio length can be used as the length of the storage container. For example, the target audio length is 1024 and the to-be-processed audio length is 5120, the greatest common divisor of the target audio length and the to-be-processed audio length is 1024, and a storage container with a length of 1024 is created to store the data set. The to-be-processed audio length 5120 is 5 times the length of 1024, and therefore 5 storage containers can be created.

[0039] S120, filling the data set corresponding to the to-be-processed audio length into all the storage containers in the buffer.

[0040] In the embodiment of the present application, the length and the number of the storage containers are matched with the to-be-processed audio length, and therefore all the data sets of the to-be-processed audio length can be stored into all the storage containers, which is convenient for subsequent reading.

[0041] In some embodiments, for example, the step S120 can include the following steps: confirming the filling times according to the number of the storage containers; and filling the data set corresponding to the to-be-processed audio length into all the storage containers in the buffer according to the filling times.

[0042] In the embodiment of the present application, if the to-be-processed audio length is 5120 and the length of the storage container is 1024, 5 storage containers are needed, and when the data set of the to-be-processed audio length is filled into the storage containers in the buffer, one storage container is filled at a time, and a total of 5 times of filling are needed. In addition, an available counter can be set in the buffer, the counter is increased by 1 each time the filling is performed, which is convenient for recording the filling times, and a readable counter can also be set, the counter is increased by 1 each time the reading is performed, which is convenient for recording the reading times. It should be noted that when the storage containers in the buffer store the data set, the reading of the storage containers can be performed at the same time as the filling of the data, instead of waiting for the complete filling of the data before the reading is performed. For example, there are 5 storage containers in the buffer, 3 of which have been filled with data and meet the reading requirements of the target recognition system, and therefore the data in the storage containers can be read and sent to the target recognition system, and the remaining data set of the to-be-processed audio length can continue to be filled into the storage containers.

[0043] S130, reading the data set in the storage container from the buffer according to the target audio length, and sending the read data set to the target recognition system as to-be-recognized data.

[0044] In the embodiment of the present application, when reading the data sets in the storage containers, the reading is also sequential. For example, if the length of the storage container is 1024 and the target audio length is 2048, two data sets in the storage containers can be read from the buffer each time and sent to the target recognition system, or one data set in the storage container can be read each time, and after reading twice, the data sets are sent, so that the read data sets can meet the reading requirements of the target recognition system. If the length of the audio to be processed is 5120, there are five data sets in the buffer, and after four storage containers are read, one storage container is left, so that the reading and sending can be performed again after waiting for new data sets to be filled.

[0045] In some embodiments, such as the present embodiment, the step S130 can include the following steps: determining the number of single reading of the data sets in the storage containers from the buffer according to the multiple relationship between the target audio length and the greatest common divisor; and sequentially reading the data sets in the storage containers from the buffer according to the number of single reading.

[0046] In the embodiment of the present application, if the target audio length is 2048 and the greatest common divisor is 1024, two data sets in the storage containers can be read each time, and if the target audio length is 4096 and the greatest common divisor is 1024, four data sets in the storage containers can be read each time.

[0047] In some embodiments, such as the present embodiment, the audio processing method further includes the following step: if a new audio length to be processed is obtained, the data sets corresponding to the new audio length to be processed are filled into all the storage containers in the buffer to replace the data sets in the storage containers.

[0048] In the embodiment of the present application, if the audio length of the audio to be recognized is 20000 and the audio length to be processed is 5120, the data sets can be obtained from the audio to be recognized all the time to obtain the audio length to be processed until all the data sets in the audio to be recognized are obtained. When a new audio length to be processed is obtained, the new audio length to be processed is filled into the storage containers in the buffer to replace the old data sets.
