A Study Of The Correlation Between The Articulation Competence Index (Aci) And The Percentage Of Words Understood In The Continuous Speech Of 4- And 5-Year-Olds Of Varying Phonological Competence, Susan Coll Mitchell

Intelligibility refers to how recognizable a speaker's words are to the listener. Severity, a broader but closely related concept, incorporates intelligibility, disability, and handicap. Many factors influence intelligibility, including speech sound production, voice, and prosody, as well as a number of linguistic and contextual factors. Clinicians and researchers in the field of speechlanguage pathology require accurate measures of intelligibility and severity to assess and describe communicative functioning and to measure change over time. Determining the most accurate and efficient measurement approaches has been the focus of recent attention in the field. This study was a preliminary investigation of the relationship …


Examining The Relationship Between Three Speech Features And Intelligibility Ratings Of Black English Preschoolers As Judged By Standard English Listeners, Britteny Sue Asher Jun 1996

Examining The Relationship Between Three Speech Features And Intelligibility Ratings Of Black English Preschoolers As Judged By Standard English Listeners, Britteny Sue Asher

Dissertations and Theses

Linguistic diversification within our public schools has demanded professional responsibility from speech-language pathologists (SLPs) serving nonstandard English speaking students. Understanding and recognizing normal cultural linguistic differences is the responsibility of the SLP. This study focused on the relationship of three speech features to intelligibility ratings of 10 preschool aged Black English speakers as assigned by 4 licensed standard English speaking SLPs with varying experience. The SLPs also rated the perceived effect of these speech features (i.e., articulation, speaking rate, and resonance) on intelligibility. Using the Pearson product-moment correlation, ratings were correlated and found to demonstrate an association between intelligibility ratings …


The Relationship Between Intelligibility And Length And Complexity Of Language In A Group Of 4- And 5-Year-Old Children, Susan Fodell Nov 1994

The Relationship Between Intelligibility And Length And Complexity Of Language In A Group Of 4- And 5-Year-Old Children, Susan Fodell

Dissertations and Theses

Previous research has indicated that speech and linguistic variables develop concurrently. When one aspect of speech and linguistic development is delayed, there are typically associated delays in another area as well. This interactive relationship has been studied extensively in the context of phonological and syntactical development, as well as fluency and syntactical development. The relationship between intelligibility and linguistic proficiency has not been studied as extensively. The purpose of this study was to examine the relationship between varying levels of intelligibility and length and complexity of language in preschool-aged children. Mean length of utterance was correlated with the mean percentage …
