Twilio Voice feature that connects phone calls to any LLM over WebSockets.
ConversationRelay handles the realtime speech-to-text, text-to-speech, and interruption management for a Twilio phone call and streams the conversation to a developer-controlled WebSocket, where any LLM can drive the dialog. It lets teams build phone voice agents on Twilio's telephony network with a choice of speech providers.
