SupportAI: A Full-Duplex AI Voice Agent for Shopify/D2C Stores

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.
