Where do AI video tools explain voiceover?

Most tools' pages cover it, in different forms: text to speech at FlexClip and Topview, voiceovers laid on a timeline at Katalist and Pictory, sound generated with the picture at Kling AI, a voice reference at Google Flow, tags that direct a reading at Morphic, and multi-character dialogue at Runway. From 10 source pages, read 2026-09-25; no maker pays to be listed.

Inclusion rule. A tool is listed when its own help page covers what the question asks. Order. Tools in alphabetical order.

Voiceover laid on afterwards and speech generated with the picture are different workflows, and the pages say which one a tool follows.

For dialogue between characters, Runway's page is the most specific: it walks through a scene with two or more speakers.

Voice cloning, where offered, has a page of its own; FlexClip and Synthesia each have one, and Descript reads a script in a clone of your own voice.

Set beside “Where do AI video tools explain voiceover?”, two passages from the guides SceneMixer publishes about its own pipeline:

SceneMixer separates the script language from the production language: the output (episode outlines, storyboards, on-screen text) follows your interface language, and target-region localization adapts character names, casting, and scenery for Western, East Asian, Southeast Asian, or Latin American audiences.

Reading a clip produces a scene-by-scene script: who is there, what happens, every line of dialogue, in order.
