| Abstract: | 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. |
