A voiceover is an aspect of your video’s production that’s heard over its visuals. As the name suggests, you're basically adding voice to play over your videos. It’s used in commercials, infomercials, television series, documentaries, and filmmaking, among other entertainment mediums.
These are what to look for when hiring voiceover artists for your animation:

1. Resume
Look through their experience. Are they fairly new or experts who have already worked with respectable names? This will also prepare your expectations if you decide to hire them.

2. Portfolio
Their portfolio will give you a taste of what they're capable of. In some cases, it can be a crucial determinant of whether you'll hire a certain candidate. Go through their voiceovers and look for both versatility and consistency in style and tone.

3. Audition Tape or a Personalized Demo Reel
Not only does it tell you whether the candidate's voice is fit for the video, but it also shows how well your candidate can follow instructions. You can either send them a sample script or a short portion of the animated video with the necessary notes for the audition.
