“…Thus, Dalston et al (1991) showed that 89% of the 117 patients studied who had received high nasality ratings on a six-point EAI scale had a high nasalance score (over 32%), corroborating the perceptual measures. But, even when the same investigator (Dalston et al, 1993) later studied patients with different dialects and/or language (Spanish), they found correlations between nasalance scores and hypernasality ratings that ranged from .52 to .83; these findings are similar to those obtained in studies by Paynter et al (1991), Nellis et al (1992), and Watterson et al (1993). In the Watterson et al (1993) investigation, the correlation between nasalance and perceptual ratings of 10 listeners with varying experience was .49.…”

Most recently, Keuning et al (2002) found low and variable correlations between nasalance and perceptual measures of nasality in speech that incorporated nasals as well as speech that was entirely free of nasal consonants.…”

“…Nasalance data have been obtained for speakers with various resonance problems (LaPine, Stewart, and Tatchel, 1991;Tatchell, Stewart, and Lapine, 1991;Dalston, Warren, and Dalston, 1991b;Nellis, Nieman, and Lehman, 1992;Dalston et al, 1993;Watterson, McFarlane, and Wright, 1993;Mahfuzh and Fletcher, 1995;Soneghet et al, 2002;Hogen Esch and Dejonckere, 2004;Nguyen, Allegro, Low, Parsin, and Campisi, 2008). However, a major prerequisite for assessing nasal resonance based on nasometric measures in a clinical population is to compare the patient scores with normative data.…”

The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.

“…Because the mean nasalance score for a passage loaded with nasal consonants is higher than that for a passage with a normal distribution of phonemes, the difference between nasalance scores for (NT-DT) is smaller than the difference between a passage loaded with nasal consonants and a passage free of nasal consonants. However, it must be noticed that passages loaded with nasal consonants are apparently better suited for perceptual evaluation of speech of speakers with perceived hyponasality [9,[16][17][18].…”

Objective: To evaluate the potential clinical use of composite measures derived from mean nasalance scores. Procedure: Speech samples with a normal distribution of phonemes (normal text, NT) and speech samples free of nasal consonants (denasal text, DT) of 43 patients with perceived hypernasality were used. The overall grade of severity, hyperrhinophonia, audible nasal emission, misarticulations associated with velopharyngeal insufficiency and intelligibility were perceptually rated on separate visual analog scales. Mean nasalance scores were computed by the Nasometer for the same speech samples on which the perceptual ratings were performed. From the mean nasalance scores computed for the NT and DT passages the difference and the quotient were calculated. The advantage could be that the derived measures provide some normalization with regard to the performance of the individual speaker. Spearman correlation coefficients were computed between these composite measures and the perceptually rated parameters. The results were compared with the correlation coefficients between the mean nasalance scores and the ratings. Setting: The Institute of Phoniatrics, Utrecht University Hospital, The Netherlands. Results: The correlations between the composite measures and the perceptual ratings were generally lower than the correlations between mean nasalance scores and the ratings. Conclusion: Normalization of the nasalance scores did not enhance the correlation with the perceptual ratings in this study.
