Polyvox for explainer and documentary channels.
Long-form narration in your voice, one script at a time.
History channels, science explainers, mythology series, recap shows. Paste a five-minute script, get a five-minute narration in your own voice, with the pronunciations you specify. The largest group of Polyvox's paying users do exactly this, in Urdu, Hindi, English, and Turkish.
Why explainer and documentary creators pick Polyvox
The pain points it removes.
A ten-minute narration takes an afternoon
Recording, listening back, redoing the paragraph you stumbled on, matching the room tone. Polyvox turns a finished script into a finished narration in about the time it takes to read it.
Names and terms come out wrong
Ancient rulers, chemical names, place names in another language. Write them phonetically in the script, generate, and only that line changes on the next take.
The channel needs a second language
Your research is done and the script exists. Polyvox translates it and narrates the translation in your voice, so the Hindi or Spanish channel sounds like the original.

FAQ
Common questions from explainer and documentary creators.
How long can one narration clip be?
Up to 5,000 characters on Pro, which is roughly six to eight minutes of speech depending on the language. Longer episodes are generated as a few clips and joined in your editor.
Can I control pacing and pauses?
Yes. Pro lets you set speed per clip and add pauses inside the script. Emotion controls are available for English clips.
How do I get a difficult name pronounced correctly?
Write it the way it sounds, in the script, the way a broadcast writer would. Regenerate and only the changed line is different.
Can I use a voice that isn't mine for narration?
Yes. Polyvox has 108 ready-made voice actors across 44 languages, including narrators and announcers. Multilingual actors keep the same voice across languages and are included with Pro.
