About Vaani
Overview
Vaani is an AI dubbing platform that accepts a source video in English, Hindi, Tamil, or any of 40+ supported languages and returns the same footage dubbed into a chosen target language. It clones the original speaker's voice from the uploaded video, so the result sounds like the same person speaking a different language rather than a stock AI narrator. Creators, broadcasters, OTT platforms, EdTech companies, news publishers, and studios use it.
Language coverage spans 13 Indic languages — Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Urdu, Odia, Sanskrit, and Nepali — plus 27 global languages that include Spanish, French, German, Japanese, Korean, Mandarin, Arabic, Portuguese, and Italian. Translation reads the visual context of each shot, so idioms and cultural references follow the scene. Lip-sync stays optional and applies to face-on frames only.
Key Benefits
- Voice cloning pulls audio straight from the uploaded source video, so no separate sample recording is needed.
- Scene-aware translation adapts idioms, tone, and cultural references to the context of each shot.
- 13 Indic languages and 27 global languages sit inside one dubbing workflow.
- Optional lip-sync handles talking-head footage with a Normal engine for cost or a Pro engine for premium output.
- Speaker diarization keeps every voice distinct when a video has multiple people on camera.
- A REST API and webhooks connect dubbing to an existing content pipeline on Studio plans and above.
How It Works
You upload a source video in MP4 format at up to 1080p. Vaani transcribes the audio with speaker diarization, then you pick a target language and the platform translates the transcript with scene-aware context, which you can review and edit line by line. You choose whether lip-sync runs, and Vaani renders the dubbed video with the cloned voice mixed against the original score for you to download as an MP4.
Use Cases
- YouTubers dub existing videos into Indic languages to reach regional viewers without re-recording.
- Broadcasters localize news segments overnight for audiences in other languages.
- EdTech companies scale course libraries across 13 Indic languages while keeping the instructor's own voice.
- OTT platforms deliver multi-language masters to regional audiences from one source video.
- B2B teams integrate dubbing into their content pipeline through the Developer API.
Why Choose This Product
The differentiator is voice provenance: Vaani clones the speaker from the source footage rather than assigning a stock narrator, which keeps a presenter's identity intact across languages. Face-aware slicing means lip-sync work and cost stay limited to frames where a face is visible, and two engines let teams trade cost against quality per project. Enterprise buyers get on-premise or private-cloud deployment, custom voice library management, SLAs, SSO, and audit logging.

Key Features
Source Voice Cloning
Vaani clones the speaker's voice directly from the uploaded source video, needing only a few seconds of on-camera speech and no separate training session.
Scene-Aware Translation
The translation model reads the visual context of each shot so idioms, cultural references, and tone adapt to the scene instead of being translated line by line in isolation.
40+ Languages
Vaani covers 13 Indic languages including Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Urdu, Odia, Sanskrit, and Nepali, plus 27 global languages.
Optional Lip-Sync
A lip-sync toggle handles talking-head shots with a Normal engine (Replicate sync/lipsync-2) or a Pro engine (sync.so sync-3) for sharper edges, profile angles, and fast cuts.
Face-Aware Slicing
Only face-on frames are processed and billed for lip-sync, while B-roll and cutaways pass through untouched.
Speaker Diarization
Transcription runs with speaker diarization so multi-speaker footage keeps each voice distinct in the dub.
Transcript Editing
Users review and edit each translated line before rendering, keeping control over the final script.
Developer API
Studio+A REST API with webhooks connects dubbing to a larger content pipeline and is available on the Studio plan and above.

Frequently asked questions about Vaani
What languages does Vaani support?
Vaani supports 13 Indic languages — Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, Urdu, Odia, Sanskrit, and Nepali — plus 27 global languages including Spanish, French, German, Japanese, Korean, Mandarin, Arabic, Portuguese, and Italian.
Do I need to record a separate voice sample to clone a voice?
No. Vaani clones the speaker's voice directly from the source video you upload. If the person talks on camera for at least a few seconds, there is enough audio to clone, so no separate recording or stock narrator library is needed.
What video files can I upload?
You upload a source video in MP4 format at up to 1080p, in English, Hindi, Tamil, or any of the 40+ supported languages, and download the finished dubbed MP4 after rendering.
Is lip-sync included in a dub?
Lip-sync is optional. Turn it on for shots where the speaker's lips are visible and leave it off for B-roll-heavy edits. Vaani offers a Normal engine (Replicate sync/lipsync-2) for cost-sensitive work and a Pro engine (sync.so sync-3) for sharper edges, profile angles, and fast cuts.
How does Vaani handle videos with multiple speakers?
Vaani transcribes the audio with speaker diarization, so multi-speaker footage keeps each voice distinct and each speaker's cloned voice is preserved in the target language.
Can I edit the translation before the video renders?
Yes. After you pick a target language, Vaani translates the transcript with scene-aware context, and you can review and edit each line before starting the render.
