Long form narration
Multi hour audiobooks and podcast episodes with a single consistent voice across chapters, no re-take burnout.
A studio in a browser tab. The booth stays optional.
Koythu is for narrators, video creators, dubbing studios and audiobook producers who do not want their output tied to studio time. Write, choose a voice, tune the tone, generate.
Script
Chapter one. It began, as most such stories do, with a knock at the door.
Narrator A
Warm, literary
Narrator B
Deep, dramatic
Narrator C
Bright, briskly
Five workflows that pay for themselves fast.
Dubbing at scale
Render the same script across twelve languages without booking twelve actors. Cadence stays native to each language.
Explainer videos
Draft a script, generate a rough cut voiceover in seconds, and iterate on tone while you edit the visuals.
Character voices
Give each character in a series a persistent voice profile. The same character sounds the same in episode one and episode forty.
Your own voice, everywhere
A consented clone of your voice can carry through when you cannot record - travel days, sick days, or content in a language you do not speak.
Draft, render, adjust. Repeat in under a minute.
- 01
Paste the chapter
Straight from your script tool. Punctuation carries into pacing, so you can shape the reading without markup.
- 02
Pick a narrator
Search the library by descriptor - warm, literary, briskly - or drop in your own consented clone.
- 03
Render and preview
A three minute chapter renders in seconds. Play it back, adjust tone or emphasis, render again.
- 04
Export
WAV or MP3 at studio grade, plus a timing sidecar file so your editor can drop scenes to phoneme boundaries.
