I know some here have problems when going out if they have to use thier female voice.
Some say they don't have one but if you work on it you will find it.
There are lots of YT videos dealing with this and a few websites too.
My female voice is pretty much my regular voice just a slight variation.
Mostly I use the upper portion of my voice box to get a more feminine tone.
Its still a bit deep but by using that portion it brings it up to a more feminine range I feel natural speaking in.
By using hand gestures and emphasis on words as women sometimes do it seems to work for me.
My Brother called one night and I was expecting my GF to call I answered hello in my femme voice well I thought Oh crap! so I said excuse me I will call him to the phone.Whew! that was close.
I answered hello and had a normal conversation with my brother.
I have a southern accent so don't be too hard on me.
This video is several years old and short but you tell me if it sounds feminine to you.
Well the video won't play sorry about that I'll try another method.
