男女说话者之间的语音差异通常是根据不同发音维度的静态声学和感知后果来考虑的。本文研究了男女声道平均尺寸差异对动态声学和发音的影响。探讨了不同维度的时变双管谐振器的时间声学后果，并考虑了对人类语音产生的可能影响。通过调查威斯康星大学x射线中26名女性和22名男性说话者的双元音产生的运动学和声学模式，寻求理论预测的经验支持。微束语音生产数据库。除了预期的声学差异外，在树皮空间中绘制的雄性和雌性形成峰轨迹的形状非常相似。然而，男性和女性的舌头运动模式却非常不同。平均男性双元音，由四个中矢状球的轨迹定义，其特点是更大的球漂移，更高的球速度，以及比女性更大的背腭狭窄。实证结果表明，性别特征的动态行为可能是解释元音系统不均匀差异的重要因素，但同时对过渡现象和欠调有更广泛的影响。(C) 2001美国声学学会。
Phonetic differences between male and female speakers are generally considered in terms of the static acoustic and perceptual consequences of different articulatory dimensions. This article investigates the dynamic acoustic and articulatory implications of differences in mean male and female vocal tract dimensions. The temporal acoustic consequences of time-varying twin-tube resonators of different dimensions are explored, and the possible implications for human speech production are considered. Empirical support for the theoretical predictions is sought by investigating the kinematic and acoustic patterns in diphthong productions from 26 female and 22 male speakers in the University of Wisconsin X-ray. Microbeam Speech Production Database. Aside from expected acoustic differences, the shape of male and female formant tracks plotted in Bark space is found to be very similar. Male and female patterns of tongue movement, however, are found to be very dissimilar. The mean male diphthong, defined by the tracks of four midsagittal pellets, is characterized by greater pellet excursions, higher pellet speed, and consistently larger dorso-palatal strictures than its female counterpart. The empirical findings suggest that gender-specific dynamic behavior could be an important factor in accounting for nonuniform vowel system differences, but at the same time having more wide-ranging implications for transitional phenomena and undershoot.
