一种基音周期检测中减小中值平滑误差的方法
In a Pitch Detection Method for Decreasing the Median Smoothing Error
摘要
Abstract
In speech signal processing,commonly used pitch detection algorithm for clean speech signal de-tection effect is better;However,the actual speech signal will be influenced by background noise,make the com-monly used detection algorithm can not achieve optimization,In order to improve the accuracy of pitch detection,in pitch detection post-processing used in a variety of smoothing techniques,but in most cases the post-processing pitch valuations still produce very big error,for this pitch for speech signal in the valuation of the median smoothing, may produce the error of pitch extraction,detection analysis,put forward a method to reduce the median smoothing error.关键词
