I'm good with voices too, but I feel like it's less an innate power than something I honed when I got interested in voice actors and started consciously listening for them in games and animated media. I enjoy picking out prolific voice actors even when they're "doing voices" and noticing the tiny differences between the different actors who have portrayed classic cartoon characters that have iconic voices. But maybe I'm only able to do that because I had some ability for it to start with!

Faces are horrible for me though. If I'm not faceblind I'm at least very face-nearsighted and usually go by other cues to recognize people. It's a good thing all those white guys don't sound alike because they sure do look alike.

There have been a lot of people who thought I could magically make electronics work by standing near them. When I worked in retail management I was often called over to fix a computer or cash register but as soon as I got close it fixed itself. But I suspect the magic was not coming from me, but from the evil spirits that conspire to embarrass people by causing the car to stop making the noise as soon as you try to show it to the mechanic, etc.
