ABSTRACT
01.What real-time dubbing is
Most dubbing is an editing step: the video finishes, then a dub is produced. Real-time dubbing removes the step. The stream is translated while it airs, and viewers in each language watch live, seconds behind the original rather than days.
Familiar is the only voice + face translation in real-time. No other tool prices real-time voice + face dubbing for streams today: audio-only tools drop the face entirely, and offline video tools cannot follow a live camera feed's face. The claim in plain words: “Dubbing is finally good. And real-time. Still your voice. Still your face.” You can watch a real-time stream dub on the demo reel; for the async side, see AI Video Dubbing, Explained.
02.How a dubbed stream works
Nothing about your main broadcast changes. You stream to your main channel exactly as you always have; Familiar dubs the feed in real time and pushes each language's version to its own channel, 10 to 30 seconds behind. A Spanish channel, a Portuguese channel, a Japanese channel, each carrying you in that language.
- On OBS, our companion app sets everything up in one click.
- Streaming from a phone: paste one extra destination URL into your streaming app. Nothing to install.
- Only you get dubbed. Friends, guests, and donation audio stay in their real voices, and music passes through untouched.
- A Do Not Translate list keeps catchphrases and names exactly as you say them.
03.Why identity matters most on live
A stream is not a video; it is a parasocial relationship. Viewers spend hours a week with a person, and the person is the product: the voice, the laugh, the way they react. A stranger voice does not merely sound wrong on a stream; it breaks the relationship the stream exists to build.
That is why we measure voice identity first. From the stable ElevenLabs Dubbing v1 API study (418 paired outputs across 11 languages, August 5, 2026):
| Measure | Result | Raw scores |
|---|---|---|
| Speaker resemblance | Familiar 27.8% higher | 0.461 vs 0.360 · all 11 languages favored Familiar |
| Predicted naturalness | Familiar 10.2% higher | exploratory |
| Review-flagged spoken-output mistakes | Familiar made 48.8% fewer | 132 vs 258 |
The newest-product study (ElevenLabs Website Dubbing V2 Alpha, 111 paired outputs) points the same way on what a stream is made of: in it, ElevenLabs made 121% more important spoken-meaning mistakes and produced 270% more background-sound error. Method, intervals, and listening examples are in the head-to-head paper and at the full benchmark.
04.Who runs dubbed streams
- Streamers on Twitch, Kick, and YouTube Live. The single biggest unlock is a non-English streamer opening the English audience: the largest viewer pool on every platform, unreachable live until now.
- Live sports and news, dubbed as they air.
- Sermons and services, for congregations that worship in more than one language.
- Live shopping, where the host sells across borders in the buyer's language and their own voice.
05.What it costs
Live dubbing displays at 42¢ per finished minute per language. Live starts on paid plans, from $35 a month with 90 live minutes included, and every paid plan dubs into all 24 target languages (Familiar covers 25 languages, any to any). The free tier covers video only, 4 minutes a month, so going live requires a paid plan. Current tiers are on the pricing page; billing mechanics are in the FAQ.
06.Latency, honestly
Dubbed channels run 10 to 30 seconds behind by design. Languages reorder ideas: the clause that ends a sentence in one language often has to begin it in another, so a system that speaks the instant you do is guessing. The delay buys enough context to translate full clauses correctly.
True same-second conversation is a research goal, not today's product. We would rather ship a correct dub 20 seconds behind than a wrong one instantly.
