An EMA Analysis of the Effect of Increasing Word Length on Consonant Production in Apraxia of Speech: A Case Study
Bartle, Carly J.; Goozee, Justine V.; Murdoch, Bruce E.
Clinical Linguistics & Phonetics, v21 n3 p189-210 Mar 2007
The effect of increasing word length on the articulatory dynamics (i.e. duration, distance, maximum acceleration, maximum deceleration, and maximum velocity) of consonant production in acquired apraxia of speech was investigated using electromagnetic articulography (EMA). Tongue-tip and tongue-back movement of one apraxic patient was recorded using the AG-200 EMA system during word-initial consonant productions in one, two, and three syllable words. Significantly deviant articulatory parameters were recorded for each of the target consonants during one, two, and three syllables words. Word length effects were most evident during the release phase of target consonant productions. The results are discussed with respect to theories of speech motor control as they relate to AOS. (Contains 6 tables and 2 figures.)
