مستخلص: Introduction: Vocal changes occur across the life span and can be reflected in acoustic measurements.
Objective: To investigate the characteristics of voice production of the Brazilian Portuguese speakers across the life span based on acoustic measures of Fundamental Frequency (f o ) and noise-to-harmonic ratio (NHR) and to verify the differences in these measures between men and women.
Methods: A total of 526 recordings from Brazilian Portuguese speakers aged 5-93 years were included. Voices from these speakers were judged with normal vocal quality for their age using the G parameter of the GRBAS scale. The recordings were divided into 12 age groups (5-7 years; 8-9; 10-11; 12; 13-15; 16-18; 19-29; 30-39; 40-49; 50-59; 60-69 and, 70-93 years old). Acoustic analysis was conducted, extracting the parameters f o and NHR through Multi-Dimensional Voice Programsoftware.
Results: For women, there was a gradual decrease in f o from childhood to older age. Older women (60-93 years old) showed a lower f o than age groups up to 19-29 years (P< 0.00). For men, there was a decrease in f o up to the age group of 13-15 years (P< 0.00) and, then, it remained stable. Differences between sexes occurred from 12 years old, with higher f o values for women than men (P< 0.00). The NHR parameter remained stable across the life span for women while higher values for older subjects were found for men (P< 0.04). Regarding sex, men showed a higher NHR value than women (P< 0.002).
Conclusion: Vocal changes occur across the life span and are reflected in the acoustic measure of f o for men and women. The beginning of vocal changes occurs from 12 years old with differences between sexes. The NHR measure was sensitive to indicate changes over a lifetime for men, with higher values for older subjects.
