Objektive Messung der normalen Nasalanz im sächsischen Sprachraum

Objective: The purpose of this study was to investigate the impact of dialect and gender and to obtain normative nasalance values for Flemish adults as measured with the Nasometer II. Subjects and Methods: One hundred and sixty-four adult subjects from the five regions in Flanders corresponding to different dialects were included in the study. The group consisted of 71 adult men and 93 adult women with a mean age of 43 years and an age range between 20 and 82 years (SD 16). Nasalance scores of connected speech using an oral, an oronasal and a nasal text were measured with the Nasometer II model 6450. Results: The nasalance scores for the oral, oronasal and nasal texts are provided in this study. No significant differences were found across the five dialects and between men and women. Conclusion: This study provides new Flemish normative data as measured with the Nasometer II model 6450. The results of this study are very important for clinical purposes and for future Flemish studies collecting nasalance scores of subjects with different dialects.

In the rehabilitation of cleft palate patients the quality of spoken language represents one of the most important aspects of successful social integration. It is therefore necessary to direct special attention to phoniatric care and speech therapy following operative reconstruction. One of the main problems is the comparison of subjective and objective measures of the degree and type of nasal disorder. In an interdisciplinary project at the University of Jena nasometry was assessed. Due to a lack of norm values for German a representative sample for the calibration of cleft palate patients and normal subjects was collected. Speech was elicited using standardized and phonetically validated reading materials. Nasalance measurements were compared with judgements made by a group of trained listeners who were asked to assess voice quality (RBH) and nasality. A database containing nasalance values and acoustic signals from 120 subjects was built up. The results generally exhibited highly significant correlations between instrumental measurements and auditory judgements. Profiles of norm values for a phonetically and statistically reliable standard for German were obtained, which in turn can be used as a comparative basis for further studies.

“…The normative nasalance scores computed by the Nasometer for the German language appeared to be slightly higher than the normative nasalance scores computed for the Dutch language. For the German language, normative nasalance scores of 13.0% for passages free of nasal consonants, 67.2% for passages loaded with nasal consonants and 33-41% for mixed (phonetically nonbalanced) passages were computed [19][20][21]. For the Dutch language, normative nasalance scores of 11.75% for passages free of nasal consonants, 52.33% for passages loaded with nasal consonants and 31.95% for passages with a normal distribution of phonemes were computed [22,23].…”

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.
