AI voiceover
Definition
A synthetic, text-to-speech narration voice generated from a script — used to narrate videos without recording a human voice.
AI voiceover (or AI text-to-speech) generates a natural-sounding narration voice from your script. Modern voices are good enough that most viewers cannot tell.
The quality difference is rarely the engine — it is how you use it: punctuate for breath, vary sentence length, and spell tricky names phonetically. Word-level timing is what lets captions sync perfectly.
Its biggest advantage is localization — one script voiced in many languages. See AI voiceover for videos.
