The movie "Do I Sound Gay" has an interesting take on this kind of thing. There's a stereotype of the "gay voice" (a bit higher-pitch, with sibilance on the "s"es, commonly incorrectly called a lisp). The 'intensity' of the voice-modifications depends largely on one's social environment. I don't remember the movie using the term "code-switching", but it certainly did seem like the same thing. I notice this myself - if I'm with other gay men I do usually adopt a bit of a changed speech-pattern totally unconsciously. Speech is so nuanced; it really seems true that 80% of what you say has little to do with the words themselves.
