| Abstract: | A new method of pitch detection in time- domain is introduced in this paper. It directly uses the shape features to estimate the matching, degree between the waveforms of speech; thus the average pitch period of speech in one frame is picked up. The results of experiments prove that this method has low quantity of cajcuating and high accuracy, it can meet the needs of real time processing. |

| Keywords: | pitch period pitch detection waveform matching center clipping |
