Postlinngually deafened adults reading the Rainbow Passage differed from hearing-control subjects in producing greater pitch variability and mean pitch on stressed and unstressed vowels, greater fluctuations in pitch within sentences, less correlation of intrinsic pitch with vowel height and slower temporal parameters. When reading the Phonetic Inventory Sentences, they revealed less differentiation of place of articulation in fricative and plosive consonants. The present findings, taken together with those of longitudinal and implant studies, are applied to constraining models of the role of self hearing in the elaboration of speech.
语后聋的成年人在朗读《彩虹段落》时，与听力正常的对照组受试者存在差异，他们在重读和非重读音节的元音上产生了更大的音高变化和平均音高，句子中的音高波动更大，固有音高与元音高度的相关性更低，时间参数更慢。在朗读《语音清单句子》时，他们在擦音和塞音的发音部位区分上表现较差。本研究结果与纵向研究和植入研究的结果相结合，被应用于限制自我听力在言语细化过程中作用的模型。
