Abstract
Assess agreement of hypernasality and audible nasal emission (ANE) ratings between audio-recordings and a clinic setting. Cross-sectional study using retrospective clinical recordings. Audio-recording ratings by two trained speech language pathologists. Percent agreement and intra- and inter-rater reliability of perceptual ratings. Intra-rater reliability (AC2) of 167 audio-recorded speech samples for the primary and secondary raters, respectively, was 0.82 and 0.79 for hypernasality; for ANE, it was 0.57 and 0.75. Inter-rater reliability was 0.77 for hypernasality and 0.63 for ANE. When comparing ratings made from audio-recording versus the original clinical ratings, intra-rater reliability was 0.85 and 0.61 (primary and secondary rater, respectively) for hypernasality and 0.21 and 0.34 for ANE. Ratings for hypernasality made from audio recordings were consistent with clinical evaluation, while ratings of ANE were not. ANE ratings made from audio recordings may not be a valid measure of velopharyngeal insufficiency speech characteristics.
