Perceptions of Simulated Stuttering and Fluency

msusca1{at}bigred.unl.edu

This study explored multiple effects of listener perceptions of different levels of simulated stuttering and fluency. A single stuttered speech sample was modified to create four additional samples of stuttering and fluency. A sixth sample of a nonstuttered signal served as a comparative baseline. Each of 60 independent listeners made quantitative and qualitative perceptual judgments upon hearingonly one of the six randomly assigned samples. Results showed a broad spectrum of qualitative and quantitative listener perceptions of the various levels of stuttering and fluency studied. Likert scale data revealed that listeners gave lower ratings to samples with increased levels of stuttering. Listener commentaries revealed fewer positive comments with increased levels of stuttering and distinctivepreferences between two 0% samples of stuttering where only prosodic features were modified. Additionally, specific perceptions of speaker competency, perceived ease in reading a passage, general comfort listening, and perceived effort in understanding the story appear to affect the global perceptions of a speaker's communication. Implications of these findings are discussed.
