“…Similar results were seen for Hungarian and Korean speaking children (26,27) and for a normal Brazilian Portuguese speaking population, including children, adolescents, young adults and adults (15) . The lower nasalance scores seen in the production of the neutral vowel is related to the position of the tongue (lower) and the size of the oral cavity (larger).…”

RESUMO Objetivo Determinar valores de nasalância de crianças falantes do Português Brasileiro sem alterações na produção da fala, atraso de linguagem e deformidades dentofaciais evidentes, aos 5 anos de idade, e verificar as diferenças entre tipos de emissão e entre gêneros. Método A nasalância foi determinada em 20 crianças, 11 do gênero masculino e idade entre 4 anos e 10 meses e 5 anos e 11 meses, utilizando um nasômetro II 6450 (KayPENTAX), na produção de oito sílabas tipo consoante-vogal e uma sequência de nove vocábulos. A significância das diferenças entre os tipos de emissões foi verificada pelo Teste de Tukey e, entre os gêneros, pelo teste de Mann-Whitney, para um nível de 5%. Resultados Os valores médios de nasalância foram os seguintes: /pa/= 10±4%, /pi/= 22±7%, /sa/= 11±5%, /si/= 24±11%, /ma/= 57±11%, /mi/= 73±13%, /la/= 14±9%, /li/= 25±11%, vocábulos (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz)= 20±6%. Na maioria das comparações, os valores de nasalância das sílabas nasais foram significantemente maiores do que os das sílabas orais (com vogal alta ou neutra) e os valores das sílabas orais com vogal alta foram significativamente maiores que os das sílabas orais com vogal neutra. Não houve diferença significante entre os gêneros. Conclusão Foram definidos valores normais de nasalância de crianças falantes do Português Brasileiro, de 5 anos de idade, sendo que a metodologia empregada pode servir de padrão para o diagnóstico precoce de desvios de nasalidade, como a hipernasalidade observada na fala de crianças com fissura palatina.

“…Originally, the speech stimuli were part of an entire 12-sentence set that included a different number of syllables (4, 8, 16, and 31 syllables) and that is frequently used for Nasometer examinations in clinical settings, including the craniofacial centers in Korea [28]. Only 4-syllable sentences in the 3 vowel contexts were analyzed for this study as young children were not able to repeat 8-syllable or longer sentences within one breath group due to their restrictions of working memory and respiration.…”

“…This study suggested that we should identify the effect of the phonetic content of the test stimuli on the test-retest variability in nasalance scores. Mean nasalance score in normative studies is influenced by phonetic contents [24-28]. In normal speakers, a higher percentage of nasal consonants in the stimulus increases the nasalance scores.…”

“…In addition, nasalance scores are sensitive to vowel contexts and have differential values depending on the ratios of high and low vowels of the speech stimulus. Literature reported that nasalance scores for high vowel sentences are significantly higher compared to those for the low vowel sentences [25-28]. For example, Ha and Cho [28] reported normal nasalance values from normal Korean-speaking 4- to 6-year-old children and adults utilizing 8 sentences devoid of nasal consonants.…”

For example, Ha and Cho [28] reported normal nasalance values from normal Korean-speaking 4- to 6-year-old children and adults utilizing 8 sentences devoid of nasal consonants. The sentences were divided into two types of vowels (high vs. low vowels), and the sentences in each vowel context included a different number of syllables (4, 8, 16, and 31 syllables).…”

Objective: The purpose of this study was to determine whether age and vowel contexts influence test-retest nasalance score variability in typically developing Korean children. Participants: Forty-five 3- to 5-year-old children with normal speech and resonance participated in the study. Methods: All subjects were asked to repeat three 4-syllable speech stimuli in high, low, or mixed vowel contexts twice after the examiner. An immediate test-retest nasalance score was assessed with no headgear change. Test and retest variability in nasalance scores was examined based on the absolute difference in nasalance scores of the first and second repetition for each stimulus. Results: A significant main effect of the vowel context on variability in nasalance scores was found, but the effect of age on nasalance variability was not significant. Mean absolute difference in nasalance scores for the stimuli in the high vowel contexts was significantly greater than for the stimuli in the low and mixed vowel contexts. Conclusions: The results suggested that variability in nasalance scores might not decrease with age and tend to show considerable individual variations. Increased variability in nasalance scores in the high vowel context might be associated with aerodynamic and acoustic characteristics resulting from physiological aspects of the vowel /i/.

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

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.
