Autocorrelation pitch detection algorithm is the key technology of speech signal processing, the efficiency of algorithm directly affects the quality of speech signal processing in real time. At present, many good detection algorithms improve the efficiency of the pitch detection algorithm. The auto-correlation pitch detection algorithm is a time-domain algorithm, which can directly frame the time-domain signal samples and find the short-time autocorrelation function, and determine the unvoiced and voiced sound according to certain criteria. A self-correlation pitch detection algorithm is provided. After experiments, it improves the detection efficiency based on maintaining good performance.
