This paper is concerned with variations in the intelligibility of speech produced for hearing-impaired listeners under two conditions. Estimates were made of the magnitude of the intelligibility differences between attempts to speak clearly and attempts to speak conversationally. Five listeners with sensorineural hearing losses were tested on groups of nonsense sentences spoken clearly and conversationally by three male talkers as a function of level and frequency-gain characteristic. The average intelligibility difference between clear and conversational speech averaged across talker was found to be 17 percentage points. To a first approximation, this difference was independent of the listener, level, and frequency-gain characteristic. Analysis of segmental-level errors was only possible for two listeners and indicated that improvements in intelligibility occurred across all phoneme classes.
本文关注在两种条件下为听力受损听众生成的语音可懂度的变化。对清晰说话和随意交谈时语音可懂度差异的大小进行了估计。对五名患有感音神经性听力损失的听众进行了测试，让他们听由三名男性说话者清晰说出和随意说出的几组无意义句子，并将其作为声级和频率增益特性的函数。发现说话者平均而言，清晰语音和随意交谈语音之间的平均可懂度差异为17个百分点。初步估计，这种差异与听众、声级和频率增益特性无关。仅对两名听众进行了音段层面错误的分析，结果表明所有音素类别的可懂度都有所提高。
