Subglottal pressure signals during phonation were evaluated by linear prediction analysis in fifteen normal adults.The first subglottal resonance frequencies, exhibited individual variation, ranging from 420 Hz to 720 Hz. The change in fundamental frequency affected resonance spectra, also suggesting individual variation of subglottal resonance. Moreover, spectrum differences among vowels indicated coupling between the supraglottal and subglottal systems during the closed phase.
