【摘要】 对36例健康青年女性组和12例较轻程度喉病患者（低频采音4000Hz范围内无法检出）的嗓音信号进行频域分析，比较其高端相对信噪比，结论是频域分析中嗓音的高频采样可提高病态嗓音的检出率．更多还原

【Abstract】 The voice signals of 36 normal girls and 12 patients with light laryngeal disease are analysed,and the abnormal voice could not be detected in the spectrum analysis of the voice signals collected with low frequency.After the harmonics-to-noise ratios on high frequency domain have been compared,it is indicated that the spectrum analysis of the voice signals collected with high frequency could increase the detecting rate of diseased voice.更多还原
