摘　　要：嗓音分析是语音识别领域的一个分支,是生物特征识别技术的重要研究领域之一。它是旨在根据人们说话或发声时嗓音波形中反映说话人生理、病理、心理和行为特征的嗓音参数,自动识别说话人身份、判读言语内容或诊断疾病的技术,具有广阔应用前景。语音识别研究已有50年的历史,而通过嗓音诊断疾病的工作在上世纪70年代才得以开展。本文介绍了嗓音诊断疾病系统、国内外研究现状和常用的嗓音处理方法,并讨论了嗓音分析在疾病诊断中的问题。最后简要展望了其应用前景。Acoustic analysis is one of the important branches of biometric recognition technology widely used now. The mainly aim of the technology is to recognize the identity of person and judge the content of speech or diagnose the illness automatically according to the features extracted from the speaker＇s waveforms. All these features are related with the characteristics of speaker＇s physiological, pathological and psychological action. Speaker recognition study has its 50-year old history already, but acoustic analysis in diagnosing disease has been founded since 1970s. This paper introduces the main concept and research background of this diagnosing system generally and discusses the problems generated during processing. At last the prospect for the applications of acoustic analysis is forecasted.
