How It Works

// Initialize: opens WebSocket to Deepgram live transcription endpoint
d.client = client.NewWSUsingCallback(liveTranscriptionOptions)
d.client.Connect()

// Transform: streams raw PCM bytes
d.client.Stream(bufio.NewReader(bytes.NewReader(in.Audio)))

// Close: graceful stop
d.client.Stop()
