Abstract
A dynamic speech recognition method includes performing a first stage: detecting sound data by using a digital microphone and storing the sound data in a first memory, generating a human voice detection signal in response to detecting a human voice from the sound data, and determining to selectively perform a second stage or a third stage according to a total effective data volume, a transmission bit rate of the digital microphone and a recognition interval time. In the second stage, the first processing circuit outputs a first command to a second processing circuit, and the second processing circuit instructs a memory access circuit to operate. In the third stage, the first processing circuit outputs a second command to the second processing circuit, and the second processing circuit instructs the memory access circuit to operate, and the second processing circuit determines whether the speech data matches a predetermined speech command.
