Abstract: Disclosed is a voice control system and method thereof. The voice control system is used in an electronic device and works in a sleep mode and a working mode. The voice control system comprises an audio detection module, an audio codec and a control module. Under the sleep mode, the audio detection module continually detects whether there is a wake-up speech in a received first audio data. If yes, the audio detection module generates a first indication signal and temporarily stores the following first audio data. When the control module is woken up by the first indication signal, the voice control system enters the working mode. Under the working mode, the control module drives the audio codec to read and process the temporarily stored first audio data to recognize control speech in the first audio data and to accordingly control the electronic device.

Abstract: An audio processing device that includes a first ADC, a second ADC, a register and a processing circuit is provided. The processing circuit executes a first audio application program corresponding to a first analog input audio stream and assigns the first analog input audio stream to the first ADC. When the processing circuit identifies that a second audio application program also corresponds to the first analog input audio stream, the processing circuit control the first ADC to process the first analog input audio stream. When second audio application program corresponds to a second analog input audio stream, the processing circuit assigns the second analog input audio stream to the second ADC for processing such that the first and the second ADCs process the first and the second analog input audio stream respectively.
