Hi girls!
Although this in and old topic, I think this is a very interesting topic.
I'd like to point out some personal experiences to make a question about it.
It is much easier for me to have a female voice speaking English (not my mother tongue).
With my mother tongue, Portuguese, I can't do that good. Sometimes I can sound very female, but every time I keep sliding down to a male voice or using a falsetto.
Spanish is much more harder. I may be a bad diagnostic, but I believe women's voice in Spain tend to be more on the throat... that makes it so hard for me to speak it as a female.
This gives me the awkward characteristic of pretending to be an american tourist on the country I live to be able to make my voice pass without worries.
And about Russian, it only goes out manly. I don't know if it is because my level is low on this language or because I am not immersed enough to learn female characteristics of the language but it it really hard.

My conclusion is that I have to make an individual specific voice training since the beginning - training voice pitch, training ups and downs and everything else - for each language. I realized I cannot develop an English female voice and just start using it with other languages as we normally do with our untrained voices...
I'd really like to know it this also happens with you and what you think of it!!
Thank you, girls!
