  title: Deepgram Diarized Transcript Intelligence
  summary: Transcribe a multi-speaker recording with diarization, then run targeted text intelligence over the transcript.
  description: >-
    A conversation analytics flow for multi-speaker recordings. The workflow
    transcribes a hosted audio file with diarization and utterance segmentation
    so each speaker turn is captured, then runs text intelligence over the
    transcript with summarization, sentiment, intents, and a set of custom
    topics supplied by the caller. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
