Abstract Details

2017, Master of Arts, Miami University, Speech Pathology and Audiology.
This study examined substitution errors for pairings of the English pure vowels (/i ¿ e æ ¿ u ¿/) in an /hVt/ context. Different measures exist to determine the impact errors have on intelligibility, including functional load and goodness. Vowel substitution errors commonly affect children with Apraxia of Speech and English Language Learners. Native monolingual English speaking listeners rated native monolingual English speakers saying the pure vowels as target /hVt/ words and all English vowels (/i ¿ e ¿ æ ¿ u ¿ o ¿ ¿/) in /hVt/ context as substitution errors on a goodness scale. This study found that there is no correlation between functional load and goodness ratings, thus the ratings should not be used to predict one another. Additionally, some vowel substitution errors are bidirectional demonstrating equally problematic vowel errors. Other vowel substitution errors show a unidirectional preference. Listeners prefer the mid central vowel /¿/ when paired with any peripheral vowel. Listener’s also show a preference for vowels that create a more frequently occurring /hVt/ word. Vowel substitution errors demonstrating a unidirectional preference should be prioritized in target selection for the populations mentioned.
