中文摘要: 自相关基音周期检测是语音信号处理的关键技术,除了保证信号处理的质量外还要注重算法的效率.通过短时自相关函数得到浊音语音的基音周期,在自相关运算过程中采用极性相关法和峰值估算法以提高运算效率.
Abstract:Autocorrelation pitch period detection is a key technique in voice signal process. Efficiency of the algorithm is also important except for the quality of the signal process． Pitch period of the dull sound is obtained through the short-time autocorrelation function，and polarity correlation and peak value estimation are used to raise the efficiency in the process of the autocorrelation．
