Which languages can be translated on a live video call?
78 languages are available for live translated calls, including Spanish, French, Portuguese, German, Arabic, Hindi, Mandarin, Japanese, Korean, Vietnamese, Swahili and Ukrainian — the list comes from the underlying translation model and changes when that model does.
Where the list comes from
The catalogue is the supported-language table of the translation model the calls run on, rather than a list assembled for marketing.
That is a meaningful difference. It means the number on the languages page is read from the same table the software uses, so the page cannot drift into claiming a language that would not actually work on a call. It also means the list is not ours to extend by wishing: when the model adds a language, the site gains it, and if the model drops one, the site loses it.
Which language pair works best?
The heavily-resourced European pairs — English with Spanish, French, Portuguese, German or Italian — are the most reliable, because they have the most training data behind them.
English↔Spanish is the pair this product was validated on end to end, on real hardware, in both directions. Everything else in the catalogue runs through the same path, but that pair is the one that has been exercised hardest.
Languages with less digital text behind them, or with heavy dialect variation, are correspondingly more variable. Tone and register travel worse than plain meaning in every pair.
Does every package include every language?
Yes. No language sits behind a larger purchase.
This is worth stating because tiered access to languages is common elsewhere, and it is a pricing structure rather than a technical constraint — the model costs the same to run whichever pair it is given.
Can the language be changed during a call?
The language pair belongs to the room and is chosen when the room is created, so it is set before anybody joins rather than swapped mid-conversation.
If two people share a language, there is nothing to translate and the call carries their own audio directly.
