There is no separate Emmy Award specifically for voice-over performances.
While voice-over work is an important part of many television programs, it's typically recognized within other categories, such as:
* Outstanding Narrator (for documentaries or similar programs)
* Outstanding Character Voice-Over Performance (for animation)
* Outstanding Writing for a Variety Special (for a voice-over in a variety show)
The specific category would depend on the nature of the voice-over performance.
