Twilio
Real-time call transcription
Twilio Media Streams pipes real-time call audio to Deepgram for transcription. The reference architecture forks audio from calls to a proxy server via WebSockets, the server forwards to Deepgram, and transcripts flow back to subscribed clients. Setup needs a Twilio number, a Deepgram API key, and ngrok for local development.
