Read case studyHow the live dub works
Translate the voice. Keep the world around it.
The voice is separated for transcription and translation. Crowd sound and music remain in place. The new voice is mixed back into the original atmosphere.
The stadium still sounds like a stadium
A goal keeps its roar. A keynote keeps the room. A bulletin keeps its bed and breaks.
Text outputs come with the dub
Return same-language captions and translated subtitles from the same session, without a separate service or vendor.
Three ways to voice it
Choose how much of the original speaker carries through
Use one consistent voice, automatically cast each speaker or carry the original speaker's own vocal character into the target language.

Dubbing questions worth asking
How does live stream dubbing work?
Send SyncWords your live stream over SRT, RTMP or HLS and choose the languages you want. Vocalics translates the speech and generates natural-sounding dubbed audio in real time, keeping the speaker's tone, pacing and emotion. Each language comes back as its own audio track inside the stream, or as a separate output for platforms that carry one audio track per stream, with captions and subtitles from the same session. The LA Kings use it to dub German hockey commentary into English live.
Is this voice cloning?
We call it voice transfer. In dubbing, the words are the speaker's own words in another language. The speaker's organization controls where that transferred voice is used.
Can Vocalics dub films and scripted series?
No. Vocalics is built for live news, sports, documentaries, and narrational content. It is not a studio dubbing service for scripted films or series.
How does a dubbed feed travel?
As additional audio tracks in the stream, as a separate output per language for single-audio destinations, or into attendee earbuds through the Events experience.
Pick a market. Keep the speaker.
We will dub something of yours into the target language and let the sound make the case.
