The problem of glottal source-vocal tract interaction is treated. The effect of the first formant load on the waveform of glottal volume flow is investigated by solving a nonlinear differential equation which describes the variation of pressure drop across the first formant load. The glottal volume flow is calculated under the influence of supraglottal and subglottal formant loads. The estimation of the glottal area function is discussed as an application of the theory developed.
研究了声门源-声道相互作用问题。通过求解描述第一共振峰负载两端压降变化的非线性微分方程，研究了第一共振峰负载对声门容积流速波形的影响。在声门上和声门下共振峰负载的影响下计算声门容积流速。作为所发展理论的一个应用，讨论了声门面积函数的估计。
