Start Translating Free → No credit card · 30+ languages · Works with vMixvMix is the pro-grade broadcast platform of choice for IRL streamers, esports productions, and conference webcasts. StreamTranslate adds a real-time translation layer on top of any vMix scene by sitting inside the Web Browser Input — the same way you'd add a lower-third or scoreboard graphic.
Speech-to-text is handled by Deepgram nova-2 for English, German, Spanish, French, Portuguese, Italian, Polish, Russian and Dutch; nova-3 covers Mandarin, Cantonese, Japanese, Korean, Arabic, and Hindi. A 7-provider translation race (GoogleFree, MyMemory, Libre, Lecto, plus Azure, DeepL, and Google paid as fallback) returns the best translation in under 500ms.
Because everything runs in the cloud and renders as a transparent browser layer, vMix doesn't pay any CPU cost — even on 4K productions. The translated subtitles are baked into your output stream before it goes to Twitch, YouTube, Restream, or any other destination.
In vMix, click Add Input → Web Browser → paste your StreamTranslate overlay URL → set transparency to On → resize and position the layer over your scene. Go live. That's it.
