Building KisanVani (किसान वाणी): An Ultra-Low-Latency Multilingual Voice Agent for Indian Agriculture with Murf Falcon & LiveKit
How we built an AI Krishi Mitra for Indian farmers featuring ultra-fast streaming TTS, persistent memory, real-time weather & Mandi price tools, human escalation, outbound alert telephony, and multi-agent specialist handoffs in 10 days.
Across rural India, millions of farmers rely on timely agricultural information—such as sowing advisories, weather forecasts, pest outbreak alerts, and Mandi (market) crop rates—to make daily decisions that affect their livelihoods. However, traditional text-based mobile apps fail for rural populations due to language barriers, literacy constraints, and complex navigation UI.
Voice is the natural interface for Bharat.
During the 10 Days of Voice Agents — #VoiceForBharat Edition challenge, we set out to build KisanVani (किसान वाणी): an empathetic, expert AI voice assistant and digital Krishi Mitra (Agriculture Friend). Built specifically for the Farm & Field track, KisanVani allows farmers to speak naturally in Hindi, Hinglish, or Indian English, receiving real-time agricultural guidance, market rates, and weather alerts with human-like responsiveness.
