本文介绍了一种无侵入、直接、客观、定量地反映发声过程中声带振动特性及嗓音嘶哑程度的自动测试与处理系统．该系统具有多路生理信号检测，电声门图参数提取，诣波噪声比分析，扰动分析，频谱分析，语话图分析等多种信息处理功能．实验与临床使用结果表明，本系统在正常与病变发声检查、艺术嗓音测试等方面具有重要应用价值．
This paper introduces an automatic test and processing system that is noninvasive, directly, objectively and quantitatively reflecting the vocal cords’ vibration characteristics and hoarseness during vocalization. The system has a variety of information processing functions such as multi-channel physiological signal detection, electro-acoustic gated image parameter extraction, frequency-to-noise ratio analysis, disturbance analysis, spectrum analysis and speech graph analysis. The experimental and clinical results show that this system has important application value in the normal and lesion vocal examination, art voice test and so on.
