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

A developer built SupportAI, a full-duplex, low-latency AI voice agent for Shopify and D2C e-commerce stores that handles real-time customer conversations over voice calls. The agent targets sub-800ms response windows, barge-in interruption handling, and e-commerce actions such as checking order status and recovering abandoned carts, and is available as a browser-based live demo without signup.

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 browser without signing up:
