声门发声效率测量系统的研制

The development of measurement system for glottal vocal efficiency

本文介绍了一种按作者提出的唇部语音气流对数比声门发声效率原理设计出的声门发声效率测量系统。该系统能在自然发声的条件下,无侵入性地测量声门发声效率,并能消除声道共鸣作用的影响。实验结果表明,该方法在定量反映声带生理与病理及其变化方面效果良好。

This paper introduces a measurement system of glottal vocal efficiency (GVE) designed according to the principle of speech-to-airflow logarithmic ratio at lip developed by authors. This system can measure GVE noninvasively under the condition of natural phonation, and eliminate the influence of vocal tract resonance on measured GVE. The results of experiment show that this method is effective for representing physiology and pathology of vocal folds and their quantitative changes.
