KayXo, so you have found a technique that is working better - thats cool. I tried two online instuctions and I had voice therapy with a therapist for several months - it always came down to getting a good resonance, which was fairly possible, but my pitch had to be low to not strain the voice. Going into a female pitch range was taking effort and as with Denjin took a toll on the vocal folds after many years, almost 2 decades. Also what really got to me after a while was that I had to consciously control my voice if I wanted to be sure it works. About half the way was subconscious and second nature, but that was not enough so I had to push it further, which was eventuall harmful. If I did not do that last push, my voice was mostly gendered a very low female voice - some even liked that about me - when I was visible - but gendered 50% male on the phone. In face to face situations it was usually accepted as female even though it was in a clearly male pitch range, but I was often asked why I had such an extremely low voice, that its unusal for a woman and so on - occasionally the connection was made to "trans".
What technique did you use and what was your original pitch of the voice before changing it?
I think everyone is different - some even say they just talk as they did talk before and they are recognized as female all the time.
