Additionally, we used General Linear Models (GLM) to test for possible effects of sex, age, and country on voice attractiveness ratings. Similarly, to test whether mean F0, range F0, and VTL of speech and singing differ between men and women or between Brazilian and Czech participants, we performed a multivariate GLM with mean F0 and F0 range as dependent variables and sex and country of targets as factors. Due to a limited samples size, we evaluated only simple models. The effect size displayed is a partial Eta-squared (?p 2 ).

We found large effects of targets’ sex on all vocal parameters; mean speech F0 (F = , df = 1, 153, p 2 = 0.878), mean speech F0 range (F = , df = 1, 153, p 2 = 0.086), VTL as measured from speech (F = , df = 1,153, p 2 = 0.934), mean singing F0 (F = , df = 1, 153, p 2 = 0.831), mean singing F0 range (F = 7.00, df = 1, 153, p = 0.009, ?p 2 = 0.045), and VTL as measured from singing (F = , df = 1, 153, p 2 = 0.911). Estimated marginal means revealed that women had a higher F0 and F0 range and shorter VTL than men (for mean values, see Table 1). There was also a significant effect of the target country on speech F0 range (F = 4.31, df = 1, 153, p = 0.040, ?p 2 = 0.028), VTL as measured from speech (F = , df = 1,153, p = 0.001, ?p 2 = 0.065), and VTL as measured from singing (F = 6.59, df = 1, 153, p = 0.011, ?p 2 = 0.042). Estimated marginal means show that Czech participants had a lower speech F0 range and longer VTL than the Brazilian participants (see Table 1 for details).
Dining table step one. Mean simple volume (F0) while the variety of fundamental volume (F0 range) within the semitones, and you can VTL (into the centimeters) for the someone.
It’s value listing your mediocre VTL procedures for men and lady (Desk step one) compare with inhabitants-height averages (Pisanski http://www.datingmentor.org/germany-mature-dating/ et al., 2014).
Reviews Anywhere between Talking and Vocal Sound
F0 mentioned regarding message try firmly absolutely coordinated which have F0 measured regarding vocal in both men (roentgen = 0.800, Letter = 73, p 2 = , df = forty-two, p dos = , df = 44, p = 0.26 inside guys, ? 2 = , df = 49, p = 0.05 in females). Email address details are hence stated independently for men and you will people however, jointly to possess Czech and you will Brazilian professionals.
Having fun with street studies (select Second Tables S6, S7 getting full habits), we found that inside boys, lower-pitched address try rated as more glamorous (Shape 1). The same stored off singing, but it relationship did not arrive at mathematical value. During the guys, a broader speech assortment, however singing assortment, is actually ranked as more attractive. Glamorous message is actually certainly from the complete SOI, but this relationship did not maintain steadily its balances from inside the jackknife resampling. The SOI is individually linked to a lowered F0 during the address and higher F0 inside the singing. Lbs had a powerful and you may positive direct influence on seen speech and you will singing attractiveness. Ages had a bad affect address elegance nevertheless perception didn’t are still secure under jackknifing (look for Second Desk S8).
Profile step one. Street analysis outcomes for F0. Arrows portray projected parameters. Matchmaking notably different from 0 (shown by the sturdy permutation produced p thinking) is actually coloured (self-confident relationship from inside the green, negative from inside the purple) and you will branded with standard design rates. Matchmaking that did not meet up with the jackknife value stability conditions was illustrated with a good dashed line. F0 = mediocre simple frequency; WSR = waist-to-neck ratio; and you may WHR = waist-to-stylish ratio.
