“…A study conducted with children from the states of Sao Paulo and Minas Gerais, aged six to ten years, showed no difference between the participants' naturalness in both the oral and nasal texts (13) . Some authors have reported that nasalance scores increase with age (7,9,(19)(20)(21)27) as a result of changes in the size and shape of the vocal tract resonance cavities caused by growth (7,20,21,28) . Therefore, this fact justifies the absence of difference between nasalance scores in the populations of the states of Sao Paulo and Minas Gerais at early age.…”

“…However, verification of the data revealed a trend of higher nasalance scores in women from Minas Gerais state compared with those of men in the same group for the nasal-2 text, as observed in some studies with adult populations (14,17,25,29) . This tendency is justified by differences in the velopharyngeal sphincter mechanism and in the vocal tract length between the genders (9,14,17,21,24,28) . Perhaps if the sample size of this study were larger, this difference would be more evident.…”

“…Because the Nasometer is a non-invasive and simple-to-use instrument, it is widely described in both the national and international literatures to objectively and directly assess speech resonance in different population samples (9)(10)(11) . The Nasometer quantifies nasalance as the percentage ratio between the acoustic data obtained by two microphones, one nasal and one oral.…”

“…It can vary within the same language and within the different dialects of this language. It may be associated with geographical area owing to the phonological effects of linguistic variation in the different regions of a country (13)(14)(15) , and may also be influenced by gender (14,(16)(17)(18) and age (7,9,(19)(20)(21) .…”

Purpose: To measure the nasalance scores of Brazilian Portuguese-speaking young adults from the states of Sao Paulo and Minas Gerais in order to investigate whether dialect variations and gender affect these scores. Methods: Nasalance was assessed in 36 individuals: 20 native residents of Sao Paulo state (mean age=23 y.o.) and 16 native residents of Minas Gerais state (mean age=24 y.o.), following the same criteria. Nasalance measures were taken using the Nasometer II 6400 (KayPentax) device based on the reading of three texts (nasal-1, nasal-2, and oral). Intergroup nasalance scores were compared using the unpaired Student's t test considering two experimental groups. Results: The nasalance scores in individuals from the states of Sao Paulo and Minas Gerais were 52.7% and 48.8% for the nasal-1 text, 49.6% and 49.9% for the nasal-2 text, and 14.3% and 9.8% for the oral text, respectively. Statistical analysis comparing the mean nasalance scores in both groups showed significant difference (p=0.03) only for the oral text, in which individuals from Sao Paulo state presented higher scores. Conclusion: Although nasalance scores were lower in individuals from Minas Gerais state compared with those of individuals from Sao Paulo state, both groups presented values within the normal range. The variable gender was not relevant in the nasalance assessment; however, a tendency for higher scores was observed in women compared with men from Minas Gerais state in the same group in the reading of the nasal-2 text. This study contributes to the knowledge of nasalance reference scores for two different populations of Brazilian Portuguese speakers; however, the results herein reported should be interpreted with caution due to the small study sample size. RESUMOObjetivo: Obter valores de nasalância de jovens adultos, falantes do português brasileiro dos estados de São Paulo e Minas Gerais, para investigar a existência de fatores influenciadores, como variação dialetal e gênero. Método: Foi avaliada a nasalidade de 36 indivíduos, 20 oriundos do Estado de São Paulo (idade média: 23 anos) e 16 de Minas Gerais (idade média: 24 anos), de ambos os gêneros, pelo Nasômetro II modelo 6400 (KayPENTAX  ) durante a leitura de três textos (nasal1, nasal2 e oral). A comparação dos valores de nasalância entre os grupos foi feita pelo teste t de Student não pareado, considerando dois grupos experimentais. Resultados: Os valores de nasalância encontrados nas populações paulista e mineira foram, respectivamente, 52,7% e 48,8% para o texto nasal1; 49,6% e 49,9% para o texto nasal2 e 14,3% e 9,8% para o texto oral. Na análise comparativa da média dos valores, verificou-se diferença no texto oral (p=0,03), sendo a nasalância dos paulistas maior que a dos mineiros, já o fator gênero não apresentou diferença significativa. Conclusão: Ambas as populações apresentaram valores de nasalância dentro dos padrões de normalidade, porém a nasalância dos mineiros foi menor que a dos paulistas. O fator gênero não mostrou influência sobre esses valores, ai...

“…Due to certain technical limitations, the Tonar was replaced in 1987 by the so-called Nasometer system, first produced by Kay Elemetrics Corporation and more recently by Kay Pentax. The use of nasometry in different countries soon has shown that nasalance varies according to the language spoken (9)(10)(11)(12)(13) . Studies with Brazilian Portuguese speakers, including children, have shown that nasalance can also vary according to age, gender or the type of emission (syllables and/or sentences) (14,15) , confirming observations for other languages (13,(16)(17)(18)(19)(20)(21)(22) .…”

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.

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.
