The present study investigated the effects of adventitious deafness on perceptual judgments of segmental and suprasegmental speech production skills. Subjects were 25 adventitiously deaf and 10 normal-hearing adult male speakers. Twelve subjects were classified as aidable profound (AP) and 13 subjects were classified as unaidable profound (UP). Each subject was judged by 15 listeners, first on seven speech and voice variables and, second, on whether they were adventitiously deaf or normal-hearing and, if adventitiously deaf, if speech rehabilitation was warranted. Both the AP and UP adventitiously deaf subjects were judged significantly different from each other and from normal-hearing subjects on all seven variables. They were, in hierarchical order: intonation, pitch, rate, nasality, vowel duration, articulation, and intensity. Aural rehabilitation was judged to be warranted in 49% of the speakers identified as being adventitiously deaf, specifically 26% of the AP speakers and 74% of the UP speakers. This finding indicates that auditory information is a necessary component for maintaining accurate speech and voice production abilities following onset of profound hearing loss after the acquisition of an adult phonological system.
本研究调查了后天性耳聋对语音和超音段言语产生技能的感知判断的影响。研究对象为25名后天性耳聋成年男性和10名听力正常的成年男性。12名受试者被归类为可助听重度聋（AP），13名受试者被归类为无助听重度聋（UP）。每位受试者由15名听众进行评判，首先针对七个语音和嗓音变量进行评判，其次评判他们是后天性耳聋还是听力正常，以及如果是后天性耳聋，是否需要言语康复。在所有七个变量上，AP和UP后天性耳聋受试者的评判结果均与彼此以及听力正常的受试者存在显著差异。按等级顺序依次为：语调、音高、语速、鼻音、元音时长、清晰度和强度。在被认定为后天性耳聋的受试者中，49%被判定需要听觉康复，具体而言，AP受试者中有26%，UP受试者中有74%。这一发现表明，在获得成人音系后发生重度听力损失时，听觉信息是维持准确语音和嗓音产生能力的必要组成部分。
