AI Avatars, Dubbing and Sound: The New Voice Tools
Build a reusable AI presenter from one photo, have it read any script, dub your videos into 18 languages and generate sound effects from a sentence.
Faces and voices are what make a video feel made rather than generated. WorkCrafter now covers both: presenters that speak your script, dubbing that keeps the original voice, and sound design from a sentence. Here's what each one is for.
Three ways to put a person on screen
They look similar and solve different problems — picking the right one saves a lot of wasted credits.
- **AI presenter** — a ready-made host reads your script. Nothing to prepare; best for quick explainers and product news.
- **My avatar** — build a presenter once from a single photo, then reuse it forever. This is the one for a consistent brand face.
- **Talking avatar** — a character copies a reference performance you upload, matching its expressions and timing. Use it when the delivery matters as much as the words.
Building your own presenter
Go to My avatars, upload one clear front-facing photo, name it, describe its personality and pick a voice. It processes for a few minutes and then it's yours permanently. Creating one is free — you only spend credits when it makes a video.
The personality field does real work. “Warm, upbeat product host who speaks in short sentences” produces a noticeably different delivery from “calm expert explaining a technical topic”. Write it the way you'd brief a human presenter.

Dub your videos into 18 languages
Dubbing translates the speech in a clip and keeps the speaker's own voice. That's the important part: your audience in another country hears you, not a stand-in. Upload the video or audio in the studio, choose the target language, and you get a new track back.
For a creator, this is the cheapest way to multiply reach: one video, a dozen language versions, same voice throughout.
Clean up a noisy recording
Voice isolation strips background noise and music from a track, leaving the speech. It's the fix for a good take recorded in a bad room. One constraint worth knowing: the clip needs to be at least five seconds long.
Sound effects from a sentence
Describe a sound and get it as audio — no library to trawl, no licensing to check. Transitions, UI feedback, ambience, impacts: it's the fastest way to make an edit feel finished.
“A soft cinematic whoosh followed by a bright confirmation chime”
“A silent cut looks unfinished. Voice, music and one good whoosh do more for perceived quality than another render at higher resolution.”— WorkCrafter
Putting it together
The tools are designed to feed each other. A realistic pipeline for a product video:
- Write the script with the text tool.
- Have your saved avatar read it — that's your spine.
- Generate two or three b-roll clips with the video tool.
- Generate a music bed and a couple of sound effects.
- Assemble it all in the editor and export.
- Dub the finished audio into your other markets.

Frequently asked questions
How many photos do I need for an avatar?
One. A clear, well-lit, front-facing photo gives the best result — the same rules as a good passport picture.
Can I use someone else's face or voice?
Only with their permission. Cloning a voice or likeness without consent is against the rules and, in many places, against the law. Use your own, or someone who has agreed.
Does dubbing change the video itself?
It produces a new audio track in the target language. Combine it with your video in the editor to publish the localised version.
Why is my isolated voice rejected?
The clip is probably shorter than five seconds — that's the minimum the tool accepts.
Start with a face
Create your presenter in My avatars and have it read a paragraph. Once you have a consistent face and voice, everything else — b-roll, music, dubbing — is just assembly.
