First with the endpoint detection of speech to voice some of the useful extracted from the (soon to mute some of the head and tail removed), and then extract the speech signal with the LPC algorithm characteristic parameters of dynamic warping (DTW algorithm) after the template library compared to standard voice inside, and finally the recognition result is D/A conversion after playing out. In this part of the design, mainly to complete the pattern matching algorithm for speech recognition part of the software.
