Voice cloning and video dubbing

Turns one recording into the same content in many languages.

Written text becomes natural speech, and an existing video becomes the same video in another language — including matching the speaker's lip movements. A specific person's voice can be recreated, with their permission.

Why use it

Reach another audience without recording everything again.

The everyday challenge

A useful training video may exist in only one language. Re-recording the script, arranging speakers and matching subtitles for every audience creates extra work each time the content changes.

What gets easier

Reuse the source recording to prepare more language versions. Your team can concentrate on reviewing meaning, pronunciation and presentation instead of rebuilding every video from scratch.

What you can do

Turn writing into speech: Prepare spoken versions of scripts, lessons or announcements. Review the voice and pronunciation before using the recording.
Dub an existing video: Produce speech in another language and match the speaker's lip movements. Keep the original visual explanation while changing the language.
Keep the message accessible: Generate subtitles alongside the speech. Where a particular person's voice is required, cloning needs that speaker's written consent.

See it in practice

One training video, more people able to use it.

An example request

“Our training is in English. Can our Hindi-speaking team use the same lesson?”

Start with the source
Provide the video, the approved script and the language needed for the new version.
Prepare the new version
Create translated speech, subtitles and the lip-matched video for your team to review.
Listen, check and approve
A language reviewer checks meaning, names, timing and tone before the video is shared.

The result: The same lesson becomes easier for another audience to follow, without organising a full new recording.

Talk through your use case

What do we need to get started?

Bring a few examples of the work you want to make easier, along with:

A clear recording or a finished script
Target languages and a pronunciation guide for names
Written speaker consent if a voice will be cloned

We agree the voices, languages and output format, then prepare a sample for review. Larger batches follow once your team is satisfied with the sample's sound and meaning.

How do you check quality and accuracy?

Ask a fluent reviewer to check the translation, especially instructions, technical terms and names.
Listen for unnatural speech and inspect subtitle timing and lip movement before publishing.

Where people stay involved

Translation and lip matching may need corrections. Your team approves the final version; permission to clone a voice is required before that work starts.

Who is this useful for?

E-learning, training, media, government communication and corporate video.

Training teams: Adapt existing lessons for staff who are more comfortable in another language.
Content teams: Spend more time on the message and less time coordinating repeat recordings.
Viewers: Follow the content through familiar speech and readable subtitles.

What should our technical team know?

TTS, STS, lip-sync and subtitle generation.

We agree the connections, access permissions, hosting and monitoring before deployment. Private infrastructure options and ongoing support can be discussed in the walkthrough.
