“…In both Czech and Danish, our results show significant sex differences with higher HNR values in female speakers than in male speakers. This is in line with the results reported by Dehqan, Ansari, and Bakhtiar for Iranian speakers, 116 Ambreen et al for Pakistani speakers, 117 and Goy et al for English speakers. 118 Nevertheless, such findings are incongruous with the expectation that women should have lower HNR as they are assumed to be breathier than men, and their voice signals should thus exhibit higher amount of noise.…”

“…Interestingly, HNR and H2*-H4* yield a greater degree of aperiodicity/breathiness in male speakers, and the magnitude of sex differences for HNR in our speakers is greater than in English speakers 119 and highly exceeds that found in Iranian speakers 116 and Pakistani speakers. 117 This might suggest either language specificity, or that other aspects of the voice are relevant for the given measures apart from breathiness. Sex differences for H2*-H4* in Czechs and Danes are greater than in English speakers.…”

Normophonic Breathiness in Czech and Danish: Are Females Breathier Than Males?

The present study compares the voice quality of female and male speech in two languages: Czech, a Slavic language, and Danish, a Germanic language. For both languages, the results based on a total of 120 vocally healthy speakers are in line with the claim that females are universally breathier than males. This was supported by the Cepstral Peak Prominence (CPP) and H1*-H2* measures, which are generally known as the most robust correlates of breathiness, and also by the H1*-A3* measure. However, the sex distinction was unsupported or even contradictory when using some other measures suggested to reflect breathiness, which provides an incentive to insist on employing a number of acoustic measures in future voice research. The perceptual component of the study nevertheless suggests that these contradictory findings are due to differences in perceived roughness rather than breathiness, and that CPP and H1*-H2* do reflect breathiness differences, and CPP in particular. We therefore conclude that it is indeed the case that female speakers are breathier than male speakers. Finally, in terms of the two robust measures (CPP and H1*-H2*), no language-specific differences in the magnitude of the effect of sex on breathiness were found.

“…The short-term perturbation measurement of amplitude, shimmer, indicates the cycle-to-cycle variation of the vocal fold in relation to the amplitude of the wave, and is influenced by the age and gender of each person 4 . Increased values of this measurement are related to roughness, hoarseness 27 and breathiness 4,10 .…”

“…Acoustic measurements reference values are extensively recommended for the comparison of findings obtained in clinical voice evaluation 2,9,10 . Hence, vocal changes that occur in the different cycles of life, in both genders, must be taken into account when searching for reference values for clinical comparisons.…”

Acoustic characteristics of voice in different cycles of life: an integrative literature review

et al. 2019

Purpose: to carry out an integrative literature review about the acoustic characteristics of healthy voice production, from childhood to old age. Methods: a bibliographic survey was conducted on the databases PubMed, SciELO, MEDLINE and LILACS, covering the last 10 years. Nineteen studies were found, meeting the proposed criteria, on acoustic measurements: F0 (fundamental frequency), jitter, shimmer and/or noise measurements, in males and females, with normal voices in their different stages of life. Results: the analysis showed that F0 is the most changing acoustic parameter as people grow up and grow old. Its values present gradual fall from childhood to old age in the female population, whereas among men such decrease lasts until adulthood. Jitter, shimmer and noise remain stable throughout childhood and adulthood, while shimmer and noise measurements increase in old age. In the literature, there is no consensus regarding increase of jitter measurements in the elderly. Conclusion: from childhood to old age, in both genders, vocal changes take place which are reflected, especially by F0. There is a scarcity of information on acoustics related to specific populations with ample age range, using the same methodology. The information in this study may guide future investigations aiming to understand natural changes occurring in the human voice, in addition to guiding in the clinical practice.

“…Thus, the shortening of the membranous vocal fold and increase in stiffness of the vibrating tissue causes an increase in fundamental frequency [14]. With respect to age, higher values of jitter and shimmer have been observed in men and women [15]. Noise measures have not been reported in the literature for voices without alterations.…”

Objectives:We aimed to standardize main vocal parameters including fundamental frequency (F0), jitter, shimmer, harmonic-noise ratio (HNR), and smoothed cepstral peak prominence (CPPs) for Mongolian adults with a normal voice across a range of age groups and genders. Methods: A total of 360 voice recordings belonging to adults between 20 and 79 years old were analyzed. An acoustic analysis was performed using the Praat Program with a sustained vowel /a/ or /α/. A one-way analysis of variance and an unpaired t-test were used to measure differences in voice parameters for the age groups and genders. Results: The mean value of F0 was higher in women (254.4 ± 17.9 Hz) compared with men (149.6 ± 15.3 Hz). The average jitter was 0.26% ± 0.12% (W = 0.25 ± 0.13) and the shimmer was 1.95% ± 0.45% (W = 2.01% ± 0.45%). The mean value of HNR was 11.9 ± 1.33 dB (W = 12.1 ± 1.36 dB) and CPPs was 16.3 dB (W = 16.1 dB). Conclusion: The F0 and HNR significantly increased with age for men. The F0 and CPPs decreased, whereas the shimmer and HNR increased with age in women.
