Rask AI

What is Rask AI?

Rask AI is a video localisation tool that translates spoken content into other languages and dubs it back onto the video, aiming to keep the original speaker’s voice rather than replacing it with a generic narrator. Upload a video, choose a target language, and Rask transcribes the speech, translates it, generates new audio using a cloned version of the speaker’s voice, and can adjust lip movement so the dubbed version looks closer to natural speech.

It’s built specifically for the localisation workflow, which sets it apart from general voice tools that generate speech from scratch rather than translating and re-voicing existing content.

Key features

• Automatic transcription. Rask transcribes the spoken audio in a source video as a starting point for translation.
• Translation. Converts the transcript into a target language, which you can review and edit before dubbing.
• Voice cloning for dubbing. Generates translated speech that keeps a version of the original speaker’s voice rather than a generic one.
• Lip-sync adjustment. Adjusts the speaker’s lip movements in the video to better match the new audio.
• Multi-language export. Produce dubbed versions of the same video in several languages from one upload.
• Subtitle generation. Create subtitles alongside dubbed audio for viewers who prefer reading along.

How to get started

1. Sign up at rask.ai.
2. Upload the video you want to translate.
3. Choose the target language or languages.
4. Review and edit the automatic transcript and translation before generating audio.
5. Generate the dubbed video, check lip sync and pronunciation, then export.

Who Rask AI is for

Course creators and educators publishing lessons to international audiences, YouTubers who want to reach viewers in other languages without re-recording, marketing teams localising product videos for new markets, and businesses that need the same training or promotional video available in multiple languages while sounding like the same presenter throughout.

It’s also useful for agencies managing localisation for several clients at once, since the review-and-edit step on transcripts and translations gives more control than a fully automated dub without any human check.

Tips for better results with Rask AI

• Review the transcript first. Automatic transcription can misread names or technical terms, so correct these before translating to avoid compounding errors.
• Keep source audio clean. Background noise and overlapping speakers make transcription and voice cloning less accurate, so a clear original recording gives better dubbed results.
• Check translated script length. Some languages naturally run longer than others when translated; use the free word counter to compare script lengths and catch potential pacing issues before dubbing.
• Preview before publishing. Watch the full dubbed video with sound to catch any lip-sync or pronunciation issues the automatic process missed.
• Start with a short clip. Test quality on a short segment before committing to translating a full-length video.

Rask AI vs alternatives

HeyGen also offers video translation with voice cloning and lip sync, but is built primarily around talking-avatar videos rather than dubbing existing footage. Synthesia focuses on corporate training videos with AI avatars and includes translation as one feature among many, rather than as its core focus. ElevenLabs provides the voice cloning and dubbing building blocks as a more general audio platform, without Rask’s dedicated video-translation workflow and lip-sync adjustment.

Is Rask AI worth it?

For creators and businesses publishing video to international audiences, Rask AI removes the need to re-record content in every language while keeping the original presenter’s voice recognisable. The free plan is enough to test translation and dubbing quality on a short video; anyone localising videos regularly, especially for multiple languages, will find a paid plan’s extra minutes necessary for consistent publishing.

The time saved compared to hiring separate voice talent and video editors for each target language is usually the deciding factor: for a single video in one extra language, manual dubbing might still be simpler, but for ongoing multilingual publishing, a dedicated tool like Rask scales much better.
