like the nike commercials say "just do it!" no better way to learn than to go out and use your voice. I did NOT sound like a woman before but I am consistently ma'amed on the phone now. Then again I am full time, before I went full time I would worry every time that my fem voice wasn't going to come back of course it did though I needed a half hour or so to get it up to speed again. I think that unless you are especially gifted there is little chance that a CDer who dresses for a social event once a month or so is going to develop a convincing Female voice because it requires emersion to really learn. My voice is still improving at least now i find myself in a place were im not sure i could "do" my old male voice without it sounding contrived. obviously i still have that lower range but those muscles are atrophying while the muscles in the higher range are much stronger now. One thing I did was sing in the car a lot that helps.
