The purpose is to investigate the auditory perceptual capacities of severely hearing-impaired persons in identification and discrimination of certain acoustic cues of speech. The general method is to compare abnormal and normal audition using tests of auditory discrimination and identification of speech sounds and of corresponding synthetic sound stimuli. The comparisons are to develop new psychoacoustic information on the speech-perception problems of persons with sensorineural hearing loss. Discrimination and identification measures are carried out for pattern differences among vowel sounds, consonant sounds, and sound spectral patterns which vary in time, such as format transitions.

目的是探讨听觉知觉能力的 严重听障者的识别和辨别能力 语音的某些声学线索。 一般的方法是比较异常 和正常的听力，使用听觉辨别测试， 语音和相应合成声音的识别 刺激。 这些比较是为了开发新的心理声学信息， 感音神经性听力损失患者的言语感知问题。 对模式进行了判别和识别 元音、辅音和声谱之间的差异 随时间变化的模式，例如格式转换。
