I have tried, I’ve tried for years. My voice is just too deep for it to sound feminine no matter how I speak, and it’s not to say that I haven’t been trying. I won’t deny that I sound slightly more feminine than I did before but it still doesn’t pass. Some people tell me it does but I do know they’re only saying it to be nice, because anyone else will greet me as miss or ma’am when they see me but then change to sir when they hear me speak, even if I’m speaking fem.
