在12名美国英语非口吃者中研究了基线和四种流畅性唤起条件--合唱阅读（CR）、节拍器起搏（MET）、延迟听觉反馈（DEAERED）和掩蔽噪声（NOISE）--之间气流和口内压的变化。在8个目标CVC单词中测量了初始爆破音和以下元音的持续时间和强度期间气流和口内压力发展的持续时间、幅度和速度。计算每个句子的语速。基线和相应的生产在每种条件下的比较显示，在峰值流量，压力上升时间，峰值瞬时压力速度，语音速率，强度和元音持续时间的显着变化。元音持续时间增加下，低音，MET，和噪音条件。峰值压力和压力速度在CR和MET期间降低，在NOISE期间增加，但在CPR期间没有变化。受试者在不同条件下修改的变量是一致的。空气动力学变量的变化与强度或速率变化无关。因此，不口吃的扬声器修改口内压力和流畅性唤起条件下的流量。
Changes in airflow and intraoral pressure between baseline and four fluency-evoking conditions--choral reading (CR), metronome pacing (MET), delayed auditory feedback (DAF), and masking noise (NOISE)--were studied in 12 American English nonstuttering speakers. The duration, amplitude, and velocity of airflow and intraoral pressure development during the initial plosive and the duration and intensity of the following vowel were measured in eight target CVC words. Speech rate was computed for each sentence. Comparisons between baseline and the corresponding production in each condition revealed significant changes in peak flow, pressure rise time, peak instantaneous pressure velocity, speech rate, intensity, and vowel duration. Vowel duration increased under DAF, MET, and NOISE conditions. Peak pressure and pressure velocity decreased during CR and MET and increased during NOISE, but did not change during DAF. Subjects were consistent in the variables they modified across conditions. Changes in the aerodynamic variables were not related to intensity or rate changes. Thus, nonstuttering speakers modify intraoral pressure and flow under fluency-evoking conditions.
