I would say that outside of my hometown someone I know would not recognize me even though I do not blend in.
I will add that I was a member of a CD social/support group a few years ago and met a lot of people not knowing where they lived. One Sunday at church, while not paying much attention, I heard a familiar voice at the front microphone during congregation share time. It caught me by surprise so I looked to the speaker and immediately knew that it was someone from my CD group. I had seen this person at church many times but had never heard him talk until that moment.
My conclusion: your voice will out you to an acquaintance more quickly than your look, and, of course, having your wife by your side will out you too.
