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.

检查了说话率的变化对相对鼻气流 (鼻气流百分比) 和对鼻知觉的影响。此外,还检查了性别和言语速率激发技术 (节拍器控制,自我控制) 的影响。19名普通演讲者各自产生一个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气流。结果表明,与正常和快速速度相比,慢速说话时的鼻流量百分比和鼻感觉均更高。男性被认为比女性更鼻音。节拍器控制率比自我控制率更高。讨论的重点是与这些发现相关的生理学。
