计算机嗓音声学检测研究进展

Research Advance in Computer Voice Vocal Detection

应用电子计算机技术的嗓音声学测试,近十年来临床研究和应用日益广泛,已成为嗓音声学客观检测的重要手段之一。它是一种客观、无创和能提供较准确可比临床资料的嗓音质量评估方法。目前应用的主要参数有基频、振幅、微扰值(频率微扰、振幅微扰)、噪声谱(谐噪比、信噪比、标准化噪声能量)等。现就此方面的研究进展进行综述。

Vocal acoustic measuement by electronic computer, which is widely studied and applied in recent ten years, has already become one of the important means of objective detection of voice acoustics. This evaluation approach of voice quality is objective, non-invasive and comparatively accurate. At present,its main parameters are fundamental frequency, amplitude of vibration, perturbation （Jitter, Shimmer）, noise spectrum （ HNR, SNR, NNE）, et al. The research advance in these fields is reviewed.
