Provider Notes
stt-async-v5 is the upload/create/poll model. stt-rt-v5 supports both AudioLab's uploaded-audio shim and open-ended live WebSocket sessions. Both support language identification, context, diarization, and native one-way or two-way translation; set translate=true together with provider.options.soniox.translation to choose the target behavior.
