Okay well you dont need a specific time to get your voice right, I had no problems for example and almost didnt work on it, so it depends on the person there is no specific time frame. That being said, I didnt even care about the voice, the words were amazing, she looked stunning, everything was perfect. Who cares about her voice, maybe she's training but she decided to keep using the male range until she knows she can keep her female range for a long time, or until she's confident enough, you don't know that, don't call someone lazy and make assumption about stuff you dont know. I don't mean to sound mean or rude, but I've read so many negative comments from cis people that getting this attitude from trans people too it's just too much.
