At the beginning of this thesis , we introduce the fundamental of the acoustics and the perceptual mechanism . next , different kinds of speech processing methods including time processing and time - frequency analysis are presented , such as short time average energy , short time cross zero analyses , short time autocorrelation function analyses and fft . at last , we focus on the sound separation , especially on single channel sound separation
在这篇文章开始的部分,我们介绍了声学的基础知识和人类声音感知的机理;接下来,我们给出了在时域处理和频域处理语音信号的一些经典的技术,比如短时平均能量分析、短时过零分析、短时自相关函数分析、快速傅立叶变换等;本文重点从理论和实验上讨论语音分离,特别是单声道语音分离的算法及其在分离音乐鼓点中应用。
