Five studies were conducted to measure changes in the perception and production of selected speech targets, with training, in three prelingually deaf patients. The two adults and one adolescent were implanted with the Cochlear (Nucleus) multiple-electrode prosthesis. The studies were perception and production of nasal consonants; perception of syllable-final consonants; perception and production of alveolar consonants; auditory-visual perception of alveolar consonants; and perception and production of vowels. Perceptual data were collected in the audition (implant)-alone condition, except for the auditory-visual perception of alveolar consonants where the audition-alone, vision-alone, and auditory-visual conditions were used. Speech perception data in the audition-alone condition were also collected from four postlingually deaf adult implant patients, without training, to indicate differences between the two classes of patients. The three prelingually deaf patients generally showed some improvements in speech production. In perception, improvements were recorded only for individual patients in some studies. The performance of the adolescent was better than that of the two adults in all cases. The perceptual performance of the postlingually deaf patients was superior to that of the prelingually deaf patients in all cases.
开展了五项研究，以测量三名语前聋患者在接受训练后对选定语音目标的感知和发音变化。两名成年人和一名青少年植入了科利耳（Nucleus）多电极假体。这些研究包括鼻音的感知和发音；音节末辅音的感知；齿龈音的感知和发音；齿龈音的视听感知；以及元音的感知和发音。除了齿龈音的视听感知采用了仅听觉、仅视觉和视听条件外，感知数据是在仅听觉（植入）条件下收集的。仅听觉条件下的语音感知数据也从未经训练的四名语后聋成年植入患者中收集，以表明两类患者之间的差异。三名语前聋患者的语音发音总体上有一些改善。在感知方面，仅在一些研究中的个别患者身上记录到了改善。在所有情况下，青少年的表现都优于两名成年人。在所有情况下，语后聋患者的感知表现都优于语前聋患者。
