Exploring Lexical Stress Perception: An Investigation Across Varied Listener Experience with Prosody
Date Completed
Spring 2024
Abstract
Prosody is a characteristic of speech that allows others to understand emotion, emphasis, and meaning of language more deeply. Perceptual accuracy by speech-language pathologists is critical to diagnosing speech disorders. This study examined perceptual abilities of three different groups in identifying lexical stress across groups. Four SLPs, 6 SLP graduate students, and 6 untrained listeners listened to 396 audio files elicited in a prior study using the lexical stress tasks from the Prosodic Profiling Elements of Prosody in Speech-Communication (PEPS-C) and the naturalistic lexical stress (NLS) tasks. Listeners were asked if syllable stress was on the first syllable, second syllable, or ambiguous. Findings show that perceptual accuracy was ~60% for SLPs, who performed significantly better than the SLP grad students and the untrained listeners. This work highlights the importance of training perceptual discrimination in speech-language pathology.
