I worked as an insurance claims adjuster in a call center for about a year. This would happen to me all the time, or my boss would play a recording of me for feedback. I would say alot people would ma'am me, I was using a gender neutral name at the time. But some people would still sir me. When I'd hear my voice though I'd have the same reaction of wanting to cry. I've been through voice therapy and I still think I sound like a man. My fiancée tells me that yeah I have a deeper voice and I don't sound like an anime chick, but cis women have deep voices too. He thinks it's sexy, haha. I guess my point is that everyone hates the sound of their own voice, and the voice in our heads are gonna sound different then it on a recording. But that doesn't mean it's not fem. I get misgendered at the fast food drive thru all the time but when i pull up to the window and they can put the voice to an obviously fem presenting person, I think it clicks that oh this person is just a girl with a deeper sexy voice!
