Graduate Student Clinicians' Perceptions of Child Speech Sound Errors.

Purpose: Speech-language pathologists (SLPs) rely on auditory perception to form judgments on child speech. This can be challenging for graduate student clinicians with limited clinical experience as they often need to judge children's speech errors using their auditory perception. This study examined how consistently graduate student clinicians used a 3-point perceptual rating scale to judge child speech. Method: Twenty-four graduate student clinicians rated single words produced by children with typically developing speech and language skills and children with speech sound disorders. All participants rated the productions using a 3-point scale, where "2" was an accurate production, "1" was a close approximation, and "0" was an inaccurate production. Ratings were solely based on the auditory signal. These ratings were compared to a consensus rating formed by two experienced SLPs. Results: Graduate student clinicians reached substantial agreement with the expert SLP rating. They reached the highest percentage agreement when rating accurate productions, and the lowest agreement when rating inaccurate productions. Conclusions: Graduate student clinicians reached substantial agreement with expert SLP rating in judging child speech using a 3-point scale when provided with detailed descriptions of each rating category. These results are consistent with previous findings on the role that clinical experience plays in speech error perception tasks and highlight the need for additional listening training in speech-language pathology graduate programs.
