There's no scientific basis for the idea that lesbians have deeper voices. Voice pitch is determined by the length and thickness of vocal cords, which is influenced by genetics, hormones, and individual characteristics. While some studies have shown that lesbian women might have a slightly lower average pitch and less pitch variation compared to heterosexual women, this difference is subtle and does not confirm any connection between sexual orientation and voice pitch.
It's important to remember that individuals within any group vary widely in their physical characteristics, including voice pitch. Stereotypes about voice and sexual orientation are not supported by evidence and contribute to harmful generalizations.
