| Abstract(in English) | To investigate influences of the short branches of the pyriform fossa and the valleculla, we computed vocal tract transfer functions and active sound intensity in three-dimensional geometrical vocal tract models using a finite element method. The vocal-tract models were based on MRI data for two Japanese male speakers during phonation of Japanese vowel /a/. Both in the simultion results of the two vocal tract models, the pyriform fossa and the valleculla contribute to the appearance and the shift of zeros and/or peaks, and affect independently to the shifts of the first 3 formant frequencies on the vocal tract transfer functions. There is little influence of the pyriform fossa or the valleculla on the vocal tract transfer function in some cases if the vocal tract models have only the pyriform fossa or the valleculla. Howerver it is suggested that the combination of the pyriform fossa or the valleculla affects the peaks and/or zeros more than the above situation at the same frequency because of the interaction with each other. |
