Anthony BarnhartA hill I will die on: It's "face recognition," not "facial recognition."
You wouldn't say "vocal recognition," would you?
Eugene Glover@MagicTony Not quite a hill I’d be willing to die on, but now that you mention it… actually… facial/vocal recognition sounds more like a technique and face/voice recognition sounds like an instance of the technique.
“We used facial recognition to perform face recognition on the suspect.”
@LoneLocust Or use vocal recognition!
