Influence of use of anchor samples during auditory perceptual ratings of compensatory articulation in cleft lip and palate

Abstract

The objectives of this study involve to identify speech samples representative of the use of Glottal Stops (GS); to establish anchor-samples (reference-samples) based on consensus ratings regarding presence and absence of GS; and to compare auditory-perceptual ratings of presence and absence of GS with and without access to anchor-samples. Methods: Phrases produced by speakers with history of cleft lip and palate and speech disorders will be rated by speech-language pathologists regarding presence and absence of GS, the samples rated with consensus will be used as anchor-samples for auditory-perceptual ratings of judges without experience in identification of GS. Data analysis: Descriptive statistics will be used with indication of percentage occurrence of GS and inferential statistics will test the hypothesis that the use of anchor-samples will result in improved agreement among judges (ANOVA, p<0.05).
