VaniFlow: Multilingual Voice AI Employee
AI voice employees that handle live customer phone calls in 3 languages with zero lag.
VaniFlow provisions autonomous AI voice employees that handle real phone calls without walkie-talkie delays. Customers can speak naturally in English, Hindi, Telugu, or switch languages mid-sentence. Built with Gemini 3.8 Live with sub-200ms latency, it handles live interruptions seamlessly, qualifies customer leads, and books appointments directly onto Google Calendar.
The Problem
Traditional IVR systems and conversational voice bots suffer from high latency, rigid single-language prompts, unnatural turn-taking, and lack of real-time interruption handling.
The Approach & Implementation
Architected a low-latency pipeline with 16kHz browser AudioWorklet streaming, a Go WebSocket bridge to Gemini 3.8 Live, native barge-in packet cancellation, and automated post-call classification using Gemini 3.8 Flash.
Measurable Outcome
Achieved sub-200ms bidirectional voice latency with natural human-like turn taking, seamless Indic code-switching, and automated CRM record synchronization.
