本研究的目的是检查薄假腭对正常成年人言语的影响。据推测，语音最初会发生改变，但说话者会很快适应该设备。十一名说话者在没有假腭的情况下发出了单词，并在装置就位的情况下每隔六次发出了单词。辅音声学最初发生了变化，但在 30 分钟内恢复到基线。从感知上看，佩戴假腭时，辅音识别和失真评级没有变化。结果表明，对于大多数说话者来说，语音的最初改变是可通过声学检测到的，但可以快速适应。使用薄假腭的研究人员必须认识到言语发生了改变，至少在最初是这样，并在他们的程序和结果解释中考虑到这一点。
The purpose of this study was to examine the effect of a thin pseudopalate on the speech of normal adults. It was hypothesized that speech would be initially altered, but speakers would adapt quickly to the device. Eleven speakers produced words without the pseudopalate and at six intervals with the appliance in place. Consonant acoustics were changed initially, but returned to baseline within ∼30 minutes. Perceptually, consonant identification and distortion ratings were unchanged when wearing the pseudopalate. Results suggest an initial alteration to speech detectable acoustically, but rapid adaptation, for most speakers. Investigators using thin pseudopalates must recognize that speech is altered, at least initially, and account for this in their procedures and interpretation of results.
