Cycle-to-cycle variations in voice fundamental frequency (jitter) and amplitude (shimmer) were derived by electroglottography for 10 children with velopharyngeal insufficiency (VPI). Jitter was found to be positively correlated with ratings of perceived nasality, whereas shimmer was found to be positively correlated with ratings of perceived hoarseness. Theoretic implications for a regulatory model of speech aerodynamics are discussed. Additionally, clinical applications, in terms of using electroglottography as a supplemental assessment procedure, are suggested.
通过电声门图法得出了10名患有腭咽闭合不全（VPI）儿童的语音基频（抖动）和振幅（闪烁）的逐周期变化。研究发现，抖动与鼻音感知评分呈正相关，而闪烁与声音嘶哑感知评分呈正相关。文中讨论了对言语空气动力学调节模型的理论意义。此外，还建议了将电声门图法用作补充评估程序的临床应用。
