streamTranscribe

Streams audio to a transcription model over a WebSocket and yields text as it is recognized.

Interim guesses arrive as .partialTranscript, which replaces the current partial, while settled text arrives as .transcriptDelta, which appends. Keeping those separate is what stops revisions from double-counting.

for try await part in streamTranscribe(
  model: DeepgramTranscriptionModel("nova-3"),
  audio: micStream
) {
  switch part {
  case .partialTranscript(let text): showInterim(text)
  case .transcriptDelta(let text): append(text)
  default: break
  }
}
