The purpose of the present study was to investigate the vibratory patterns of the vocal folds during pulse register phonation. Glottal area-time functions were calculated from three high speed laryngeal films (4000 frames/second) obtained during phonation of the schwa vowel in pulse register by a normally hearing and speaking adult female. The results for the first film indicated that each of 35 consecutive vibratory cycles of the vocal folds consisted of a single opening/closing gesture followed by a lengthy closed phase. The analysis of the second film revealed that each of 33 consecutive vibratory cycles consisted of a double opening/closing vocal fold pattern, followed by a long closed phase. For the third film, the results indicated that each of 26 consecutive vibratory cycles of the vocal folds consisted of either a double or triple opening/closing gesture followed by a lengthy closed period. From these data, it appears that one of the physiological descriptors of pulse phonation is multiple, as well as single, vocal fold vibratory patterning.
本研究的目的是调查脉冲发声时声带的振动模式。通过一名听力和言语正常的成年女性在脉冲发声中发央元音时获得的三张高速喉部影片（4000帧/秒）计算声门面积-时间函数。第一部影片的结果表明，声带的35个连续振动周期中的每一个都由一个单一的开闭动作，随后是一个较长的闭合阶段组成。第二部影片的分析显示，33个连续振动周期中的每一个都由一个双开合声带模式，随后是一个长闭合阶段组成。对于第三部影片，结果表明，声带的26个连续振动周期中的每一个都由一个双或三个开闭动作，随后是一个较长的闭合期组成。从这些数据来看，脉冲发声的生理特征之一似乎是声带的多重振动模式以及单一振动模式。
