| Abstract(in English) | Using area functions of the five Japanese vowels, glottal opening effects on the transfer function were examined by introducing a glottal impedance. Because the vocal tract resonance approached an open-tube resonance under the open-glotis condition, the first formant frequency increased. The fourth formant induced by the laryngeal cavity was shifted to a higher frequency and damped until it disappeared, because the laryngeal cavity resonance increased in frequency and attenuated. At the other formants, a node of volume velocity appeared at the junction between the laryngeal and pharyngeal cavities, and the vocal tract resonance could therefore be approximated by a closed-tube resonance of the vocal tract excluding the laryngeal cavity. |
