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．
Thirty-six healthy young women and 12 patients with mild degree laryngeal disease (low-frequency sounding 4000Hz range can not be detected) in the frequency domain of voice signals, compared with its high-end relative signal to noise ratio, the conclusion is the frequency domain analysis of voice The high-frequency sampling can improve the detection rate of pathological voice.
