Sub-300ms Conversational
Voice AI for E-Commerce.
A global retail marketplace handling 50,000+ daily customer calls was struggling with high call center wait times. We engineered an ultra-fast WebRTC voice AI pipeline handling 12,000 concurrent calls with human-like turn-taking.
18-minute average wait times during seasonal surges.
Customer satisfaction plummeted to 68% during holiday spikes as call centers became overwhelmed. Traditional IVRs caused customer frustration, while previous voicebots suffered from 1.5s robotic delays.
Streaming WebRTC with continuous interruption handling.
We connected LiveKit WebRTC, Deepgram Nova-2, Groq LPU inference, and Cartesia Sonic speech synthesis. The agent pauses instantly when interrupted by the user and executes real-time order tracking and refunds.
