“…F0 tends to approach between genders as age increases. The decreases of F0 in women is consistent with the data available in other languages [5,6,7,3,8,9] and in EP [20,21], and has been attributed to the endocrinological changes that occur after menopause [7,36,7,1,37]. For men there is less agreement across studies, and our results tend to confirm the trend that F0 decreases until middle age and increases again at an advanced age [1,7,2,3,11,8].…”

“…For EP, the few available data didn't show significant changes with age [21]. The increase of F0 in males may be associated with the muscle atrophy, or with an increase in stiffness of vocal folds tissue with ageing [36,37,1].…”

“…VSA continuously decreased with age for men. For women VSA decreased from the age group [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] to [50-65], it increased over the range [65][66][67][68][69][70][71][72][73][74][75][76][77][78][79], and then decreased in the older age. The ANOVA showed no statistical effect of age on VSA (F(3;101)=1.1; p=0.339).…”

“…The analysis of variance revealed a large main effect of gender on VSA (F(1;101)=1409.9; p<0.001). For both genders, the highest mean value of VSA was observed for the age group [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. VSA continuously decreased with age for men.…”

Age-Related Changes in European Portuguese Vowel Acoustics

This study addresses effects of age and gender on acoustics of European Portuguese oral vowels, given to the fact of conflicting findings reported in prior research. Fundamental frequency (F0), formant frequencies (F1 and F2) and duration of vowels produced by a group of 113 adults, aged between 35 and 97 years old, were measured. Vowel space area (VSA) according to gender and age was also analysed. The results revealed that the most consistent age-related effect was an increase in vowel duration in both genders. F0 decreases above [50-64] for female and for male data suggests a slight drop over the age range [35-64] and then an increase in an older age. That is, F0 tends to be closer between genders as age increases. In general, there is no evidence that F1 and F2 frequencies were lowering as age increased. Furthermore, there were no changes to VSA with ageing. These results provide a base of information to establish vowel acoustics normal patterns of ageing among Portuguese adults.

“…The male f0 results showed a statistically significant difference between normal and pathological voices, but literature [40] indicates that both normal and pathological voices f0 values in our databases are within the normal range. Female f0 values were also within the normal range according to previous studies [16,40], but normal and pathological voices in the AVFAD did not present statistically significant differences. For both genders, the results support previously published scientific evidence [16,18,35], suggesting that the f0 parameter does not allow to distinguish between a normal and a pathological voice.…”

A new open access resource called Advanced Voice Function Assessment Databases (AVFAD) was developed, based on a sample of 709 individuals (346 clinically diagnosed with vocal pathology and 363 with no vocal alterations) recruited in Portugal. All clinical conditions were registered according to the Classification Manual of Voice Disorders-I. Participants were audio-recorded, producing the following vocal tasks: Sustaining vowels /a, i, u/; reading of six CAPE-V sentences; reading a phonetically balanced text; spontaneous speech. The AVFAD are comprised of 8648 uncompressed audio files and an additional database file with 19 Praat Voice Report parameter values and 16 clinical data entries per participant. An annotated segment of the vowel /a/ for each participant was analysed automatically with a Praat script. Radial graphs were generated considering that all variables had an approximately normal distribution, and using previously calculated average and standard deviation values for all parameters. The normal and pathological f0 mean, Jitter ppq5, Shimmer apq11 and Harmonics-to-Noise-Ratio characteristics were compared. An additional analysis of the relation between the acoustic parameters and gender, age group, smoking habits, body mass index and voice usage, was considered. The AVFAD will allow future cooperative work and testing of non-invasive methods for voice pathology diagnosis.
