OBJECTIVE: The correlation between the nasalance score and the perceptual rating of several aspects of speech of speakers with @entity1739 ( @entity1739 ) by six speech-language pathologists was evaluated. PROCEDURE: The overall grade of severity, @entity2422 , audible nasal emission, misarticulations, and intelligibility were rated on visual analog scales. Speech samples with a normal distribution of phonemes (normal text [NT]) and those free of nasal consonants (denasal text [DT]) of 43 @entity1 with @entity1739 were used. Mean nasalance scores were computed for the speech samples, and Spearman correlation coefficients were computed between the mean nasalance score and the five parameters of the differentiated rating. SETTING: The Institute of Phoniatrics, Utrecht University Hospital, The Netherlands. RESULTS: The correlation coefficient between the mean nasalance and the perceptual rating of @entity2422 ranged among judges from .31 to .56 for NT speech samples and .36 to .60 for DT speech samples. Only small differences were found between speech pathologists with and without expertise in @entity2419 speech. The rating of the overall grade of severity appeared to correlate quite well with the rating of the intelligibility (r(NT) = .77, r(DT) = .79). Lower correlation coefficients, ranging from .34 to .71, were found between overall grade of severity and @entity2422 , audible nasal emission, and misarticulations. CONCLUSIONS: A low correlation between the nasalance and the perceptual rating of @entity2422 was found. The parameter overall grade of severity appeared to be determined mainly by the parameter intelligibility. Expertise in rating of @entity2419 speech does not guarantee a high correlation between instrumental measurement and perceptual rating.
