Abstract

Production variability, traditionally associated with AOS, constitutes a potential threat to test reliability for single word intelligibility. In this investigation, we examined test-retest reliability for 13 apraxic speakers. Using a speech sample consisting of 50 monosyllabic words and 11 normal listeners responding through orthographic transcription, overall intelligibility was highly consistent for identical target samples recorded on the same day. Item-by-item analysis of listener responses indicated that this stability was not due to consistency in either articulation changes or how listeners perceived the errors. Therefore, clinical applications should consider both speech sample size and listening group size carefully.
