含噪语音的基音周期提取算法
Pitch detection algorithm for noisy speech
摘要
Abstract
The background noise has a great influence on the accurate extraction of pitch period. For the EMD soft-threshold de-noising method can be effective against the background noise,one novel method is proposed for pitch period extraction of noisy speech. Combined with the EMD soft-threshold de-noising method and center clipping, this method preprocesses the speech signal,then employs the signal waveform in time donation for matching estimation, in order to acquire the accurate pitch period. The implementing simulation results demonstrate that, the proposed method has a higher accuracy compared with traditional methods.关键词
