Nasalance during use of pharyngeal and glottal place of production.
OBJECTIVE
This study obtained nasalance scores during use of compensatory articulation (CA) and compared nasalance between groups with and without hypernasality and with and without CA.


METHODS
Speech samples were obtained from 43 individuals with and without velopharyngeal dysfunction during repetition of 20 phrases originating 860 audio recordings and their respective nasometric values. After excluding 143 recordings due to low quality, the remaining 717 samples were rated by three speech language pathologists (SLPs), independently, for presence or absence of hypernasality and CA. Nasalance scores for the 553 samples rated with 100% agreement among the SLPs were grouped according to the auditory-perceptual ratings: Group 1 (G1) - included samples without hypernasality and without CA (n=191); Group2 (G2) - included samples with hypernasality and without CA (n=288); Group 3 (G3) - included samples with hypernasality and with pharyngeal fricative (n=33); Group 4 (G4) - included samples with hypernasality and with glottal stop (n=41).


RESULTS
Analysis of variance (ANOVA) revealed significant difference nasalance scores which were significantly higher for G2, G3, and G4 (p<0.0001) when compared to G1. The use of pharyngeal fricative (G3), particularly during /f/ (p=0.0018) and /s/ (p=0.0017) productions resulted in nasalance scores significantly higher than scores found for G2.


CONCLUSIONS
Significantly higher nasalance values where identified during use of pharyngeal fricative.
