Abstract

The purpose of this study was to investigate the relationship of perturbation measures, jitter and shimmer, and ratings of acceptability by naive listeners. Six tracheoesophageal (TEP) speakers and 14 naive listeners participated in the study. Each speaker was recorded while reading The Rainbow passage. The six samples of voice were then presented to the listeners for rating. The naive listeners used an equal appearing seven pint scale to rate voice acceptability. No significant correlation was found between the perturbation measures and the ratings of acceptability. Due to the small subject size in this study, the findings are inconclusive. The results due suggest that methods of predicting and judging voice quality in TEP speakers are not the same as those used for judging voice quality in laryngeal speakers.
