Transcription + translation through a single stream

Bengali translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and translation streams mid-sentence and both arrive together in a single labeled token stream.

Turn it on by adding a translation block to your request. Translation runs on the same WebSocket and the same model. Translated tokens come back interleaved with transcripts, with no extra round trip.
