The relationships between the waveform and the spectrum of the pulsating transglottal airflow during vowel phonation are analyzed in singers and nonsingers. The waveform, called the flow glottogram, is analyzed by means of inverse filtering, and the spectrum is determined either directly, by submitting the flow glottogram to spectrum analysis, or indirectly, by measuring spectral changes accompanying phonatory changes under conditions of constant vowel articulation. The peak-to-peak amplitude of the flow glottogram pulses shows a strong relationship with the amplitude of the source spectrum fundamental and varies considerably during phonation, presumably depending on the degree of glottal ab/adduction. The negative peak amplitude of the differentiated flow glottogram shows a high correlation with the sound pressure level of the vowel.
分析了歌手和非歌手在元音发声过程中脉动经声门气流的波形与频谱之间的关系。通过逆滤波分析称为气流声门图的波形，并通过将气流声门图进行频谱分析直接确定频谱，或在元音发音恒定的条件下通过测量伴随发声变化的频谱变化间接确定频谱。气流声门图脉冲的峰峰值幅度与源频谱基频的幅度显示出很强的关系，并且在发声过程中变化很大，这可能取决于声门开闭的程度。微分气流声门图的负峰值幅度与元音的声压级高度相关。
