Results showed that homosexual men displayed significantly higher pitch modulation patterns and less breathy voices compared to heterosexual men, with values shifted toward those of heterosexual women.

Lastly, homosexual men seem to produce a more expanded vowel space than heterosexual men for some specific vowels Rendall et al. Although vocal breathiness has been suggested to be an important component of femininity for female voices Van Borsel et al.

We studied four sexually dimorphic acoustic features relevant for the qualification of feminine versus masculine voices: the fundamental frequency, its modulation, and two understudied acoustic features of speech, the harmonics-to-noise ratio a proxy of vocal breathiness and the jitter a proxy of vocal roughness.

For example, popular stereotypes regarding the speech of homosexual men generally attribute speech patterns characteristic of the opposite sex, i. Regarding acoustic features of speech, researchers have hypothesized a feminization of such characteristics in homosexual men, but previous investigations have so far produced mixed results.

The gender atypicality hypothesis suggests that gender atypical traits in homosexuals could be used as cues to indicate sexual orientation. These findings emphasize the idea that specific phenotypic traits may be influenced by sexual orientation and may be used as cues to detect or advertise it.

Testosterone, a male sex hormone, has thus been intensively studied as it was found to be associated, for instance, with facial e. To fill these gaps, we explored potential differences in acoustic features of speech between homosexual and heterosexual native French men and investigated whether the former showed a trend toward feminization by comparing theirs to that of heterosexual native French women.

Lastly, testosterone levels did not influence any of the investigated acoustic features. Moreover, studies have shown that both men and women are able to accurately assess sexual orientation from both sexes from various features such as the face or body movements Ambady et al.

In line with the speech feminization hypothesis, homosexual men could indeed potentially exhibit higher values of HNR and lower values of jitter, but, so far, no studies have tackled this issue. Differences between heterosexual and homosexual individuals have thus been studied on a diverse set of traits such as face e.

Researches have tried to assess if the feminized traits in homosexual men can be attributable to proximate mechanisms such as the differences in sex hormone levels.

Combined with the literature conducted in other languages, our findings bring new support for the feminization hypothesis and suggest that the feminization of some acoustic features could be shared across languages. Aside these acoustic speech features, other characteristics could vary with sexual orientation, such as vocal breathiness and roughness that are, respectively, captured by the harmonics-to-noise ratio HNR and the jitter.

Although little is known about their physiological mechanisms, both the HNR and jitter have also been suggested to be sensitive to hormonal influx as they both relate to the oscillations of the vocal folds, which possess receptors to circulating androgens Pisanski et al.

Lastly, we examined whether testosterone levels mediated the association between speech acoustic features and sexual orientation. Moreover, most studies have been conducted with English-speaking populations, which calls for further cross-linguistic examinations.
