What is an AI voiceover?
An AI voiceover is narration generated by a text-to-speech model instead of recorded by a human. Modern voices carry natural pacing, emphasis, and emotion, making them the standard narration method for faceless videos. Good systems also let you pick a voice, adjust stability and speed, or clone a specific voice.
The gap between robotic TTS and current AI voices is the single biggest reason faceless content stopped sounding cheap. Current models breathe, pause at commas, stress the right words, and hold a consistent character across a ten-minute script.
In practice you choose a voice once per channel and keep it — voice consistency is brand consistency for a faceless channel. Scripts written for the ear (short sentences, concrete nouns) make any voice sound noticeably better.
