The effects of variation in speaking rate on relative nasal airflow (percent nasal flow) and on the perception of nasality were examined. In addition, the effects of gender and speech rate elicitation techniques (metronome-controlled, self-controlled) were examined. Nineteen normal speakers each produced a stimulus phrase containing nonnasal sounds. Oral and nasal airflows were measured using the Rothenberg aerodynamic system. Results indicated that percent nasal flow and perception of nasality were both greater at slow speaking rates compared to normal and fast rates. Males were perceived as more nasal than females. The metronome-controlled rates were associated with greater nasality than the self-controlled rates. Discussion focuses on physiological correlates to these findings.

:检查了语速变化对鼻相对气流(鼻流量百分比)和鼻感的影响。此外,还检查了性别和语速激发技术(节拍器控制,自我控制)的效果。十九个普通说话者各自产生了包含非鼻音的刺激短语。使用Rothenberg空气动力学系统测量口腔和鼻腔的气流。结果表明,与正常人和快人相比,慢语速时的鼻流量和鼻感百分率都更高。男性被认为比女性更鼻腔。节拍器控制的比率比自控的比率更大。讨论的重点是与这些发现相关的生理因素。
