Reddit reviews Queerly Phrased: Language, Gender, and Sexuality (Oxford Studies in Sociolinguistics)

There is definitely a "gay voice" and it's the subject of much study in sociolinguistics. One of my professors has studied gay speakers of Javanese and Indonesian. And one of my friends is doing his thesis on the sociolinguistics of gay speakers in Melbourne.

Of course the OP was unlikely to get a good answer in /r/askreddit. If he was genuinely curious, he should have come to /r/linguistics.

There are two routes you can go. If you are trained in linguistics, or know somebody who is, you can investigate language differences across sexualities directly, which in my opinion, is the best way to learn and become an expert on the subject. If not, there are a few written resources you can check out such as:

• Beyond the Lavender Lexicon: Authenticity, Imagination, and Appropriation in Lesbian and Gay Languages
