AI dubbing

Live AI dubbing for YouTube

Captions reach the audience that reads. Dubbing reaches the audience that listens. Vocalics, the SyncWords AI dubbing offering, dubs live news, sports and narrated programming in real time.

Explore Live AI Dubbing

Dub into 86 languages

Natural-sounding AI dubbing in real time across 86 languages, with 900+ voices and regional accent options.

The speaker stays themselves

Voice transfer carries the original speaker's tone, pacing and emotion in real time across 38 languages. Preset voices and voice casting cover the rest.

One stream per language

YouTube carries one audio track per stream, so each dubbed language comes back as its own ready-to-publish stream: a Spanish broadcast running alongside your English one. Closed captions and subtitles are included with every dub.
