Bipolar is only a suspicion right now, but since we do suspect I thought I'd share. My speaking voice is pretty normal (I hate it but many people do dislike the sound of their own voice). I talk a LOT. I have always talked a lot. That's just my personality. Probably the chattiest introvert out there. lol. However when I am having what I suspect is a hypomanic episode I talk even more, particularly in the evening. It's like I ramp up socially in the evening rather than slowing down. My husband has mentione this a few times
