“…Suppose now that the physiological changes to the larynx and vocal folds (see Linville, 2001 for a summary) accompanied by age-dependent changes in breathing and efficiency of laryngeal airway valving Hixon, 1987, 1992;Huber and Spruill, 2008;Melcon et al, 1989) bring about the kinds of changes to fundamental frequency that have been observed in this paper. Unless F 1 changes as well, then, according to this auditory theory, the cues to phonetic vowel height will be disrupted.…”

This paper presents a longitudinal analysis of the extent to which age affects F 0 and formant frequencies. Five speakers at two time intervals showed a clear effect for F 0 and F 1 but no systematic effects for F 2 or F 3 . In two speakers for which recordings were available in successive years over a 50 year period, results showed with increasing age a decrease in both F 0 and F 1 for a female speaker and a Vshaped pattern, i.e. a decrease followed by an increase in both F 0 and F 1 for a male speaker. This analysis also provided strong evidence that F 1 approximately tracked F 0 across the years: i.e., the rate of change of (the logarithm of) F 0 and F 1 were generally the same. We then also tested that the changes in F 1 were not an acoustic artifact of changing F 0 . Perception experiments with the main aim of assessing whether changes in F 1 contributed to age judgments beyond those from F 0 showed that the contribution of F 1 was inconsistent and negligible. The general conclusion is that age-related changes in F 1 may be compensatory to offset a physiologically induced decline in F 0 and thereby maintain a relatively constant auditory distance between F 0 and F 1 .

“…Muscular and phonatory compensation might explain the lack of an interaction between age and amplitude. Indeed, elderly adults display a greater expansion of the chest and lungs and more abdominal movement than necessary when asked to increase vocal amplitude (Stathopoulos and Sapienza 1997;Baker et al 2001;Huber and Spruill 2008). They also initiate phonation at a higher lung volume and use greater percent of their lung volume per syllable (Hoit and Hixon 1987;Hoit et al 1989;Sperry and Klich 1992), and they have a more pressed pattern of glottal vibration than young adults (Ahmad et al 2012).…”

The manner and extent to which voice amplitude and frequency control mechanisms change with age is not well understood. The related question of whether the assessment of one's own voice evolves with age, concomitant with the acoustical changes that the voice undergoes, also remains unanswered. In the present study, we characterized the aging of voice production mechanisms (amplitude, frequency), compared the aging voice in different experimental contexts (vowel utterance, connected speech) and examined the relationship between voice self-assessment and age-related voice acoustical changes. Eighty healthy adults (20 to 75 years old) participated in the study, which involved computation of several acoustical measures of voice (including measures of fundamental frequency, voice amplitude, and stability) as well as self-assessments of voice. Because depression is frequent in older adults, depression and anxiety scores were also measured. As was expected, analyses revealed age effects on most acoustical measures. However, there was no interaction between age and the ability to produce high/low voice amplitude/frequency, suggesting that voice amplitude and frequency control mechanisms are preserved in aging. Multiple mediation analyses demonstrated that the relationship between age and voice self-assessment was moderated by depression and anxiety scores. Taken together, these results reveal that while voice production undergoes important changes throughout aging, the ability to increase/decrease the amplitude and frequency of voice are preserved, at least within the age range studied, and that depression and anxiety scores have a stronger impact on perceived voice quality than acoustical changes themselves.

“…Estudos da função respiratória no idoso apontam para mudanças importantes apresentando um declínio pequeno nos anos iniciais da terceira idade e acelerado nas idades avançadas 8 , diferentemente do que ocorre na infância, quando o aumento da idade favorece o aumento das medidas de função pulmonar 7 . Dentre as modificações do aparelho respiratório pode-se destacar a perda da elasticidade do tecido pulmonar, entretanto, ocorrem também: diminuição das estruturas respiratórias, diminuição da complacência das vênulas e arteríolas e aumento da fibrose do revestimento de capilares, além do depósito de colágeno ou hialinização, com influências no suporte respiratório para a fala 9,10 .…”

RESUMOObjetivo: analisar medidas da dinâmica respiratória em participantes de grupos de terceira idade. Método: participaram 41 pessoas, 32 do sexo feminino e nove do masculino, idade média de 69,90 anos. A avaliação foi realizada por meio das medidas de tempos máximos de fonação (TMF) das vogais /a/, /i/, /u/, das consoantes /s/ e /z/ e contagem de números; relação s/z; medida de capacidade vital (CV) e cocientes fônicos simples (CFS) e composto (CFC). Resultados: os valores médios dos indivíduos do sexo masculino para os TMF das vogais, consoantes e contagem de números foram respectivamente, 18,11s; 19,22s; 19,11s; 15,22s e 15,61s e 18,77s, sendo 0,98 o valor da relação s/z. No sexo feminino, as médias das mesmas medidas de TMF foram respectivamente 13,94s; 14,19s; 13,98s; 10,11s e 11,63s; 13,90s, sendo 0,92 a relação s/z. A média de TMF das vogais foi significativamente maior que a média das consoantes no grupo feminino. O valor médio da CV sem oclusão nasal no sexo feminino foi de 2.247ml e no masculino de 3.211 ml. Foi verificada relação significante entre a medida de CV e a variável idade, no grupo feminino. Os valores médios do CFS nos grupos de homens e mulheres foram respectivamente 182,11 ml/s e 176,58 ml/s e do CFC, 184,35 ml/s e 186,93 ml/s. Conclusão: as medidas da dinâmica respiratória dos participantes estiveram próximas aos valores de referência para adultos na literatura, bem como próximos aos de estudos de idosos, havendo diferenças para mais ou para menos nas diferentes medidas estudadas. DESCRITORES: INTRODUÇÃOAs medidas de dinâmica respiratória compõem diversos protocolos de avaliação vocal de indivíduos em várias faixas etárias, por apresentarem dados do aproveitamento do ar pulmonar na fonação, bem como, do funcionamento glótico 1,2 Dentre as medidas utilizadas destacamos a capacidade vital e os tempos máximos de fonação de vogais e consoantes, sendo que a partir deles podem ser calculados a relação s/z e o cociente fônico simples e composto. Diversos estudos mostraram a validade dessas medidas, a melhor forma de utilizá-las 3,4 , apontaram a necessidade de uso para controle de tratamentos 5 e tentaram encontrar dados normativos em diversas faixas etárias 6,7 . Estudos da função respiratória no idoso apontam para mudanças importantes apresentando um declínio pequeno nos anos iniciais da terceira idade e acelerado nas idades avançadas 8 , diferentemente
