Purpose: To correlate nasalance scores and speech nasality of operated unilateral cleft lip and palate children.
Methods: This prospective study involved auditory perceptual identification of nasality by three experienced speech-language pathologists who judged recorded phrases produced by 30 children (mean age of 6y 7m). Nasalance measures obtained simultaneously to audio recordings were also analyzed. The speech samples included two pressure consonant sentences, one with [p] and another with [s] sounds. Inter-judgment agreement for the total (N=60) phrases judged by the speech-language pathologists was obtained (82.4% for [p] and 90.6% for [s]). Intra- judgment agreement for duplicated sentences was 85% for [p] and 92% for [s] sounds. The speech-language pathologists were then instructed to judge individually the speech nasality of the 60 phrases using a 4 points scale. Nasalance scores for these 60 phrases were then obtained. Mean speech nasality and nasalance scores were correlated.
Results: Mean values of 1.41 and 1.45 (indicative of mild hypernasality) were obtained for the [p] and [s] phrases, respectively, from perceptual judgments. Mean nasalance scores were 34% ([p] phrase) and 39% ([s] phrase). Although significant, low correlation was found between speech nasality and nasalance scores for the two investigated phrases ([p]; r=0,41; p=0,005; [s]; r= 0,47; p=0,0008).
Conclusion: Mild hypernasality as identified in children’s speech with a cleft palate may disfavor correlation findings between speech nasality and nasalance scores. Longer speech stimuli and samples, including higher degrees of hypernasality, are recommended for future studies.
