I honestly don't know what happened to my vocal chords during HRT. Every once in a while I could feel parts inside my throat moving around on their own like they were being reconfigured or something.
I'm not sure how to word this but I started obtaining a feminine voice by testing my vocal chords and encouraging them to produce noise the way my throat was....telling me to? if that makes sense. There are muscles in the throat, and like all of my other muscles, my throat muscles were affected by hormone replacement therapy. Singing helped a lot too, plus I've always had this almost supernatural ability to mimic voices, so I understand why not everyone would experience their voice changing.
Let me share with you what I believe to be the difference between how a male and a female uses their voice.
When a male changes his pitch or notes, he is usually using the muscles that move the addam's apple up and down, which is why it moves around so much when you see males singing.
Women, on the other hand, use their cricothyroid muscles (the ones positioned below the cartilage in the throat) to stretch and release their vocal chords in order to change their tone while keeping their addam's apple in the same relaxed position.
Also, males tend to form their words by using their deep voice muscles and by using the heavy volume of their breath, where as women kind of release steady streams of different vocal pitches, if that makes sense, while using their lips and tongue to form their words, which tends to give them clearer pronounciation.
Women gain volume by using the cavities inside their head as a 'sounding box' whereas men use their breath and chest to FORCE the volume out.
I realize most of this makes no sense. It's hard to describe it in words.
