🎙️ I Built SupportAI: A Full-Duplex AI Voice Agent for Shopify/D2C Stores (Here’s How You Can Test It)

Hey DEV Community! 👋 Managing customer support and recovering abandoned carts for e-commerce stores using traditional text-only chatbots often feels clunky. Customers drop off, issues get delayed, and midnight support tickets sit unanswered. To solve this, I built SupportAI—a full-duplex, low-latency AI Voice Agent designed to handle real-time customer conversations over voice calls. ⚡ What Makes Full-Duplex Voice Tricky? Unlike standard STT (Speech-To-Text) -> LLM -> TTS pipelines that feel slow with 2–3 second delays, full-duplex voice agents need: Ultra-Low Latency: Natural conversational turn-taking (sub-800ms response window). Interruption Handling (Barge-in): If the customer speaks while the AI is talking, the AI must instantly stop and listen. E-Commerce Context: Dynamic execution of actions like checking order status, handling skips/swaps, or recovering abandoned carts in real time. 🚀 Try It Out Live You can test the full-duplex voice agent live in your
