- Pitch extraction is a key task of ahumming query system.The purpose of this paper isto find a method to extract pitch accuratelyfortwo input modes, humming and singing.According to the characteristics of Chinese pronunciation, this paper presentsa new method, namely the Pitch Extraction of Subject Extension.According to the differencesbetween humming and singing signals, this method respectively chooses energy threshold and ratio of energy and entropy to detect endpoint of notes.The candidate method and the shortest distance method are used to determine the pitch periods of the voiced segments, and subject extension method is used to determine the pitch periods of the voiced/unvoiced mixed segments. Finally this algorithm is implemented in a small database, andis compared withother similar algorithms. Experiments show our algorithm is more accurate and robust.
