受试者安装了一个实验性牙科器具，该器具具有降低和收缩牙槽腭轮廓的作用。对不戴假肢和戴假肢的受试者在言语适应的两个阶段的说话录音进行了声学分析，并通过判断性评估来评估器具在掩饰声音方面的效果。佩戴假肢所产生的咝音和元音变化的类型和程度存在个体差异。在涉及将不熟悉的假体放入口中后立即获得的录音的说话者身份验证任务中，听众犯的错误比在使用器具一周后的录音或未佩戴假体时相隔一周的录音中犯的错误要多。
Subjects were fitted with an experimental dental appliance which had the effect of lowering and retracting the alveolar-palatal contour. Recordings of subjects speaking without the prosthesis and with the prosthesis at two stages of speech adaptation were analyzed acoustically and by judgmental evaluation for the effect of the appliance in disguising the voice. Individual differences were found in the type and extent of sibilant anf vowel changes produced by wearing the prosthesis. Listeners made more errors on a speaker authentication task involving recordings obtained immediately after the unfamiliar prosthesis was placed in the mouth than on recordings made after a week of accomodation to the appliance, or recordings made a week apart when no prosthesis was worn.
