摘要
文章介绍了用嗓音中谐波分量与噪声分量的比值来客观定量地评估嗓音嘶哑程度的方法，并对提取谐波噪声比（ＨＮＲ）的具体算法做了分析讨论．实验和临床使用表明，这个声学参数能够很好地反映病变语音的特性。
An objective and quantitative method, which uses the ratio of harmonics to noise components to estimate the hoarse degree of a voice, is described, and the practical algorithm thatis used to extract the harmonics to noise ratio(HNR)is discussed in detail. Experiment and clinical application indicates that this acoustic parameter can reflect the characteristics of pathological speech effectively and has important application value.
