“…severely disturbed), the NSI 2.0 index on data point 4 had a lower value (-15.06) when compared to data points 1 (-11.79), 2 (-14.78). It should be mentioned that Bettens, Wuyts [43] reported that the interval of NSI 2.0 ± 2.68 for children defines the 95% confidence interval. Hence, if a new obtained NSI 2.0 value lies within this interval for a specific patient, the observed change is not considered to be a result of physiological changes.…”

“…Moreover, despite the fact that the NSI 2.0 correlates significantly with perceived hypernasality [43], Watterson, Lewis [44] pointed out that nasalance scores may be increased in children with audible nasal airflow problems, thus causing inconsistency with raters' judgments. Given that on data point 4, audible nasal emission was frequently heard on pressure consonants in patient 1 (Table 4), this might be a plausible explanation for present findings.…”

Nasality in Homosexual Men: A Comparison with Heterosexual Men and Women

et al. 2018

Several studies reported that pitch and articulation may vary according to a person's sexual orientation. The purpose of this study was to investigate whether homosexual males also demonstrate differences in nasal resonance compared to heterosexual males. Speech samples of 30 self-identified homosexual males, 35 heterosexual males, and 34 heterosexual females were compared both instrumentally and perceptually. Nasalance scores were calculated for the sounds /a/, /i/, /u/, and /m/ and for an oronasal, oral, and nasal text. In addition, the Nasality Severity Index was determined. Spontaneous speech samples were used for a perceptual evaluation of nasal resonance. Neither the nasalance scores nor the Nasality Severity Index were significantly different between the homosexual and heterosexual males. Heterosexual females, on the other hand, showed significantly higher nasalance values for the oronasal and oral text and a significantly lower Nasality Severity Index than both the homosexual and the heterosexual males. The perceptual judgment revealed no significant differences between the three groups. The results of this study suggest that, in contrast to pitch and articulation, nasality does not tend to vary with sexual orientation.
