嘶哑语音声带质量块模型特征拟合的研究

根据语音的发音模型,对实际语音信号进行预测分析,并通过逆滤波获取准确的声门体速度波形。利用声带的质量块模型,对声门波进行拟合,获取表征发音者的声带质量块模型特征参数,用于嘶哑语音的分析与诊断.实验结果表明,该分析诊断系统可以提供很有实用价值的拟合数据,还为更深入地研究语音产生机理提供可行的分析方法.

The analysis of approaching for vocal cord mass model features of hoarse speech

In this paper,according to the sound production model,the practical speech signal is an-alyzed by Linear Prediction technique,the glottal body velocity is exactly given by means of Inverse Filtering method;The glottal waveform is approached with vocal cord mass model,the feature parame-ter of vocal cord model is obtained,it is used to the analysis and diagnosis of hoarse speech.Experimental.results reveal that the analysis system has pragmatic value and provides a feasible method for stady of speech producing mechanism.
