Languages
Varmir's acoustic model recognises 200+ languages. Translation rides on NLLB-200, which speaks the same set.
Recognition
Source language is auto-detected by default. Pass language=<ISO-639-1> if you already know it — that skips one detection pass and shaves about 30 ms off latency.
Translation
Set translate_to to any supported language code. The translation pipeline always finalises a sentence first, so partial translations only ship for completed clauses.
Common language codes
The full list is 200+ entries; here are the ones most apps reach for.
