Background: McNeil and colleagues argued that individuals with pure apraxia of speech
(AOS) have low variability of speech error type and error location within repeated …

Background: Variability in speech sound errors has been regarded as a primary
characteristic of apraxia of speech (AOS). Early research deemed errors extremely …

Purpose: There is persistent uncertainty about whether sound error consistency is a valid
criterion for differentiating between apraxia of speech (AOS) and aphasia with phonemic …

Purpose This study was conducted to evaluate the clinical utility of error variability for
differentiating between apraxia of speech (AOS) and aphasia with phonemic paraphasia …

Purpose Diagnostic recommendations for acquired apraxia of speech (AOS) have been
contradictory concerning whether speech sound errors are consistent or variable. Studies …

Background: Many researchers and clinicians have suggested that a definitive characteristic
of adult apraxia of speech (AOS) is that the speech sound errors are highly variable …

Purpose This retrospective analysis examined group differences in error rate across 4
contextual variables (clusters vs. singletons, syllable position, number of syllables, and …

Purpose The primary characteristics used to define acquired apraxia of speech (AOS) have
evolved to better reflect a disorder of motor planning/programming. However, there is debate …

Background: Apraxia of speech (AOS) is an acquired sensorimotor disorder characterised
by an impairment in the ability to program purposeful movements for speech in the absence …

Early apraxia of speech (AOS) research depicted errors as being unpredictable resulting in
a number of different error types on repeated productions of the same stimuli. However …
