Building Samar: My 10-Day Voice AI Agent Journey with Murf Falcon Over the past 10 days, I built Samar , a multilingual AI voice agent for a Bharat Digital Bank use case as part of the 10 Days of Voice Agents – VoiceForBharat Edition challenge. The project started as a simple voice assistant and gradually evolved into a more complete Voice AI system capable of remembering users, using real-time tools, making outbound calls, escalating sensitive situations to humans, analyzing calls, and handing specialized conversations to another AI agent. 🎯 The Problem Banking can sometimes be difficult to navigate, especially when users need quick information or assistance without going through multiple screens and menus. I wanted to build a voice-first banking assistant that could provide natural conversations while also maintaining security and knowing when it should involve a human. That's where Samar comes in. 🤖 What is Samar? Samar is a multilingual banking voice agent designed to help users with general banking-related queries. It can: Answer general banking questions Provide financial information Remember returning users with consent Fetch real-time information using tools Find nearby branches Provide exchange-rate information Make outbound reminder calls Escalate sensitive issues to human support Track call analytics Hand specialized conversations to a specialist agent The voice experience is powered by Murf Falcon , the fastest TTS API used in this challenge. 🏗️ How the System Works At a high level, the voice interaction follows this flow: User Speech ↓ Speech-to-Text ↓ LLM / Agent Logic ↓ Memory or Tool Calling ↓ Text-to-Speech ↓ User hears the response The system uses real-time voice communication through LiveKit, an LLM for reasoning and conversation, speech recognition for understanding the user, and Murf Falcon for natural voice generation. 🚀 Important Features 1. Voice AI with Guardrails Samar has a clear banking role and follows safety rules. It does not ask users
