Artisan, TRAI-compliant AI voice agents that speak natural Hinglish, qualify leads around the clock with outbound AI calling, and pass every compliance check — thoughtfully crafted for India's banks, NBFCs and insurers.

An AI voice agent is an automated, multilingual conversational AI system that conducts real phone calls — qualifying leads, sending EMI reminders, cross-selling products and handling customer queries — without a human agent. VoiceBrew's AI Voice Agent for NBFC India is purpose-built for Indian BFSI compliance, Hinglish conversations and high-volume outbound campaigns.
Our agents use natural Hinglish AI voice agent conversations with contextual responses, pauses and fillers. In our testing, over 70% of callers engage naturally. We always disclose AI usage where required by TRAI and RBI compliance guidelines.
Every call runs five automated pre-call checks: TRAI timing window (9am–9pm IST), DND registry lookup, frequency caps, consent verification and prompt guardrail scanning. Non-compliant calls are automatically blocked. VoiceBrew is India's most thorough TRAI-compliant AI calling software, with complete audit logs for every campaign.
Hindi, Hinglish (code-mixed), English, Tamil, Telugu, Marathi, Bengali and Kannada — making VoiceBrew India's most comprehensive multilingual AI voice bot platform for BFSI. New languages are added quarterly.
