I to like Bettylou couldn’t answer this one. I do try to decrease the volume an raise the pitch a little. This helps give me a little bit more feminine sounding voice but doesn’t go very far and I know it. On my recent hair coloring adventure I didn’t even try to feminize my voice, I just reveled in enjoying the experience and my hairdresser was so nice. If it was not for covid I would have given her the biggest hug. I have been called ma’am over the phone so maybe my voice is close to passing already.
