The only ability I have is to tell if someone is a singer just from hearing their speaking voice.
It's strange, but sometimes the way people speak sounds confident and musical, and the way they pronounce things or annunciate is clear and somewhat pleasing to the ear (I'm not sure how to words it)
I'll listen to people speak with their friends and I can honestly tell who among them can sing.
But maybe that's something everyone can do. Usually, voice actors and announcers are pretty good singers (for obvious reasons).
