半波差分频谱对于汉语声母和韵母的区分特性

研究了听觉感知系统对于动态语音特征的响应特点，在此基础上提出了半波差分频谱的概念，接着研究了半波差分谱对于汉语普通话声韵母的区分度，并通过一组非特定人全音节实验证实半波差分谱是一种优于差分倒谱的语音动态特性。

Discrimination Character of the Half-Wave Differential Spectrum to the Mandarin Initials and Finals

The response feature of the auditory perception system to the dynamic part of the phonetic speech spectrum is studied, based on which a concept of half wave differential spectrum is proposed. Then the discrimination character of the half wave differential spectrum to the Mandarin initials and finals is studied. A group of experiments on the whole Chinese syllables with unparticular persons show that the half wave differential spectrum can discriminate the initials and finals of Chinese syllables, and that it is a better dynamic representation of speech than the differential spectrum.
