The purpose of this study was to determine if stutters and nonstutters differed in their ability to initiate phonation repeatedly with a gentle voice onset. Ten stutterers and ten nonstutterers were asked to phonate the vowel /a/ with an average rise time slower than 52.3 dB/sec while starting the voice at or below 63 dB SPL. Voice productions were monitored by a voice monitor, which is used in the administration of the Precision Fluency Shaping Program. Measurements of number of attempts and time to reach criterion, percentage of correct productions, and intensity levels of each production were made. There were no significant differences between the two groups for any of the variables examined. Results were compared with other studies demonstrating phonatory differences between stutterers and nonstutterers.
本研究的目的是确定口吃者和非口吃者在以柔和的起音反复发声方面的能力是否存在差异。10名口吃者和10名非口吃者被要求在以低于63 dB声压级起始发声的同时，以平均上升时间慢于52.3 dB/秒的速度发出元音/a/。发声过程由语音监测器进行监测，该监测器用于精准流畅度塑造计划的实施过程中。记录尝试次数、达到标准的时间、正确发声的百分比以及每次发声的强度水平。在所检查的任何变量方面，两组之间均无显著差异。研究结果与其他表明口吃者和非口吃者发声存在差异的研究进行了比较。
