摘要: Acoustic effects of the time-varying glottal area due to vocal fold vibration on laryngeal cavity resonance were investigated based tract functions and acoustic analysis. The consists vestibular ventricular parts larynx, gives rise a regional within tract, with this imparting an extra formant pattern. Vocal transfer five Japanese vowels uttered by three male subjects calculated under open- closed-glottis conditions. results revealed that appears at frequency region from 3.0 3.7kHz when glottis is closed disappears it open. Real spectra estimated periods vowel sounds also showed on-off pattern pitch period. Furthermore, time-domain analysis indicated component could be observed as pitch-synchronized rise-a...
