The relationship between pitch deviancy and other aspects of speech production that affect intelligibiliyy of deaf speech was investigated. The speech skills assessed included the following: ratings of pitch deviancy, ratings of overall intelligibility, production of the prosodic features--stress, intonation, and pause, and production of phonemes. Children who could not sustain phonation had speech that was consistently judged unintelligible. This group of children also had pure tone averages greater than 90 dB. For the remaining children, the relationship among pitch deviancy, intelligibility, and hearing level was variable. The highest intercorrelations were among prosodic feature production, phoneme production, and intelligibility.
研究了音高偏差与影响聋人言语可懂度的言语产生其他方面之间的关系。评估的言语技能包括以下方面：音高偏差评分、整体可懂度评分、韵律特征（重音、语调、停顿）的产生以及音素的产生。无法持续发声的儿童的言语一直被判定为不可懂。这组儿童的纯音平均听阈也高于90分贝。对于其余儿童，音高偏差、可懂度和听力水平之间的关系各不相同。韵律特征产生、音素产生和可懂度之间的相互关联度最高。
