I immediately subconsciously reverted to my normal voice upon meeting her.

You could have always switched later. :P Like, no one I work with ever says anything despite me shifting between accidentally doing old voice (typically if really tired and/or congested), basically the voice I'm trying to do for now (idk what I want long-term, so relatively minimal changes from old voice), and accidentally switching to a customer-service-esque voice (which for some reason is really high pitched). I did once have a child to laugh at the contrast of me suddenly doing customer-service-voice with the very deep voice of the person I was responding too. And its not like I'm out at work.
