Although the higher-pitched sounds of female voices and particularly mothers’ voices are preferred, newborns would still rather hear a male voice than silence.
I want to see research on this with pregnant people with deep or T affected voices. And if they're defining the gender of a voice by pitch or by factors like prosody or timbre. A low pitched voice can be read as female 100% of the time if the speaker's prosody is typical of women. A high voice with prosody typical of men will also be gendered as male. We can't extrapolate that babies prefer high voices and female voices from data featuring only gestational parents with voices unaffected by T of typical pitch and prosody
