Error patterns during repetition of consonant-vowel-consonant syllables by apraxic speakers.
Nine speakers with verbal apraxia repeated 12 consonant-vowel-consonant target syllables four times each. The apraxic speakers produced 71 of the 108 pairs of productions (66%) in the same manner for first and last trials. Significantly more errors were produced in voiced than in voiceless contexts. Differences in the number of misarticulations of target words containing the vowels /i, a, u/ were not significant. Clinical implications are discussed and additional investigation is suggested.
