The influence of word length on syllable duration in aphasia: Acoustic analyses. Baum, S. R Aphasiology, 6(5):501-513.
doi  abstract   bibtex   
Examined syllable duration reduction in words of increasing length in 10 non-fluent (NON-FLT) and 8 fluent aphasic patients (aged 33-83 yrs) and 10 age-matched normal controls. Ss produced 4 repetitions of 10 sets of 3 words each: a monosyllabic root word, a 2-syllable word containing the root word, and a 3-syllable word containing the root word. Acoustic analyses revealed that normal speakers consistently reduce root syllable duration (RSD) in 2-syllable words as compared to 1-syllable words; a further reduction in RSD occurs for 3-syllable words relative to 2-syllable words. Both NON-FLT and fluent aphasic Ss demonstrated a reduction in RSD in 2-syllable words as compared to monosyllabic words; for the NON-FLT aphasics this reduction was smaller in magnitude than that exhibited by normals. Root durations were not further decreased in 3-syllable as compared to 2-syllable words for either aphasic group. Results indicate a deficit in the implementation of a rule of temporal control in the NON-FLT aphasic group. (PsycLIT Database Copyright 1993 American Psychological Assn, all rights reserved)
