Synopsis

Production-ready voice ordering template for a coffee/drinks cart: customers call a Twilio number, Deepgram Agent API (Flux STT + Gemini 2.5 Flash + Aura-2 TTS) handles natural drink ordering through a FastAPI WebSocket bridge, with Twilio SMS confirmations and a live staff dashboard. Menu and prompt are configurable via a single menu_config.json.

Reasoning

Clears all disqualifiers: it's a multi-component, multi-vendor template (Twilio + Deepgram + Gemini) with a named industry/use case (coffee shop drink ordering by phone), a forkable GitHub repo containing prompt/config/code, and clearly fillable schema fields. Self-published by Deepgram. Strong fit for the directory.
