Narrow phonetic transcriptions and prosodic judgments were made of single-word imitations by apraxic (AOS), conduction aphasic (CA), and ataxic dysarthric (AD) speakers. AOS and AD subjects showed similar vowel error patterns, particularly predominant errors in low, tense, and back vowels, more distortions than other types of vowel errors, and predominant errors in initial position of words and in monosyllabic words. The CA subjects displayed a different vowel error pattern, notably more substitutions than distortions, more errors in polysyllabic than monosyllabic words, and more errors in noninitial than initial positions of words. Analysis of prosodic features identifiable at the single-word level (e.g., syllabic stress, juncture, and struggles to initiate or complete productions) indicated that syllabic stress errors and more difficulty initiating than completing word production were characteristic of AOS and AD but not CA subjects.
对失用性构音障碍（AOS）、传导性失语（CA）和共济失调性构音障碍（AD）患者的单字模仿进行了精细的语音转录和韵律判断。AOS和AD受试者表现出相似的元音错误模式，特别是在低元音、紧元音和后元音中存在明显错误，比其他类型的元音错误有更多的扭曲，并且在单词的起始位置和单音节词中存在明显错误。CA受试者表现出不同的元音错误模式，特别是替代错误比扭曲错误更多，多音节词中的错误比单音节词更多，并且在单词的非起始位置比起始位置有更多错误。对单字水平上可识别的韵律特征（例如音节重音、连音以及开始或完成发音的困难）的分析表明，音节重音错误以及开始单词发音比完成发音更困难是AOS和AD受试者的特征，而CA受试者则没有。
