One thing they insisted was that I use full voice all the time when doing exercises, to develop my new voice without any 'tricks' besides consciously shifting my resonance to my head as best as possible using the exercises to develop that and to make sure I work throughout my full range. It made sense to me when they explained it that way.
Today I made my first intentional sound, and it sounded like the old trained voice, but was full instead of forced into a female 'shape'. I now know I am not maimed in any way, will be able to continue to communicate at no worse than before levels. That's a relief (though I wasn't bothered much that it would be otherwise).
Still absolutely no pain or discomfort besides a slight feeling of having been to a football game and yelled too much for my team. One thing I've noticed is how much meaningless noise I used to make. Having to be silent has taught me that I have a continual patter of self-talk, repeating things said on TV, singing along with the radio, etc. I guess I don't like living in silence? I am hoping this exercise in restraint will help me be more comfortable without noise. I think that would be a good thing for me.
I am a firm believer in visualization and mental practice when it comes to sports and life. Every time I imagine talking, like when I want to sing along or say some comment to my spouse, I imagine it in my new voice fully realized. I 'hear' my voice in my head being female. I listen to women speak and mentally make my new voice fit into the conversation flawlessly. Essentially, I practice sounding comfortable in my female voice all the time, but mentally rather than out loud. It will help me be motivated to reach that state after I start exercises, and also help me feel comfortable with that tone in my head. I expect the dog will stop listening to me now
