[0026] It is worth mentioning that in the related art, a sound engineer is needed to repair the audio. After the sound engineer repairs the audio, the voice data of the audio is sent to the programmer, and the programmer loads the voice data into the program for downloading and then compiling. The compiled voice data is then burned into the voice chip on the development board (demo board). The sound engineer listens to the sound played by the voice chip on the development board to determine whether the needs of the customer can be met. If it is determined that the needs of the customer cannot be met, this process needs to be repeated. This process often needs to be performed multiple times to achieve the ideal sound repair effect, and the time for downloading, compiling, and burning is long, which often requires a lot of time and a lot of engineering power. The present application can directly receive the voice data, voice setting parameters, and voice chip type transmitted by the host computer 200 through the communication circuit 10. There is no need for the programmer to download the voice data to the program, and there is no need to burn it into the voice chip.
