The live payload

Same envelope as all streaming providers — new_text, running transcript buffer, words[], end_of_turn, echoed custom_attributes — documented in Live Transcription.

Streaming providers do not produce a post-call transcript. Need both? Re-transcribe the recording with a post-call provider after the call.
