livekit — LiveKit format
pipecat — Pipecat format
deepgram — Deepgram format
cekura (default) — [{"role": "Testing Agent"|"Main Agent", "content": "...", "start_time": 0.0, "end_time": 2.5}]. Valid roles are "Testing Agent" and "Main Agent" only — using "agent" or "user" will return a validation error.
none-mono — mono audio with no transcript; Cekura generates the transcript automatically.

Omit this field to use the default Cekura format.

cekura - cekura
