Acoustic coupling between the voiced sound source and the time-varying acoustic load during phonation was simulated by combining the vocal-fold model of [S. Adachi etal., J. Acoust. Soc. Am 117(5) (2005)] with the vocal-tract model of [P. Mokhtari etal., Speech Commun. 50, 179–190 (2008)]. The combined simulation model enables to analyze the dynamic behavior of the vocal folds due to the time-varying shape of the vocal tract. An example of vocal-fold behavior is shown for sustained phonation of the Japanese vowel sequence “aiueo.” [This research was partly supported by Kakenhi (Grant Nos. 21500184, 21300071).]
