# AI Dubbing

Your speakers, heard in other languages as they talk: live speech-to-speech dubbing, in step with the video, in the player and in your streams.

- **Languages**: 75
- **Outputs**: HLS / RTMP / SRT
- **Status**: Beta

Engines: Google Gemini Live Translate.

## What it does

### Speech to speech

No captions in between: Gemini Live Translate turns the speaker's voice straight into speech in another language, translating while they are still talking.

### Follows language changes

When a speaker switches language in the middle of a live stream, the dubbing follows without a restart.

### Matches the speaker

The dubbed voice follows the original speaker, including their gender.

### In sync with the picture

Every dubbed track stays aligned with the original video, so lips and slides line up with what viewers hear.

### Wherever your audience listens

An alternative audio track per language in the HLS player, or the dubbed audio in place of the original in RTMP and SRT streams. Listening on the captions page is coming soon.
