项目摘要

Acoustics of human vowel sounds are usually described by using the source-filter theory. In this theory, a laryngeal sound is treated as a planar sound source, and characteristics of airflow from lungs is not considered at all. In the present study, the airflow in a larynx was experimentally analyzed to clarify phonation mechanisms and seek better modeling of a laryngeal sound source. Experimental results show clearly that periodic change and high frequency fluctuation in the airflow velocity provides crucial information to create better simulation models of the phonation mechanism.
人类元音的声学通常使用源滤波器理论来描述。在该理论中,喉部声音被视为平面声源,并且根本不考虑来自肺部的气流特征。在本研究中,对喉部气流进行了实验分析,以阐明发声机制并寻求更好的喉部声源建模。实验结果清楚地表明,气流速度的周期性变化和高频波动为创建更好的发声机制模拟模型提供了关键信息。
