I used to work in an office taking calls and the vast majority of male callers took me for a woman. They called me things like love, pet, miss and such. The middle-aged women didn't make any remarks either way but I also got called love and pet from eldery women. In fact, face-to-face, many elderly women who couldn't see very well took me for a girl with my grown-out hair.
My partner tells me that I still sound feminine, not stereotypically feminine but on the andro side of female. Recently I was on radio and listening back to the podcast it sure sounded like a woman's voice - my voice never really seemed to break fully.
As for mannerisms and speech, people have told me I talk like a woman, lots of hands and feminine patterns. It's never something I stopped to think about, it's just always been the way I have talked, and I guess that's a reason why a lot of people take me for a gay man when they meet me. Upon meeting me for the first time one of my partner's friends told her that I talk and act like a woman.
