Building NEONPLUS: My Journey Through the 10 Days of AI Voice Agents Challenge

A developer built NEONPLUS, a production-ready voice agent for Indian users, during the 10 Days of AI Voice Agents (VoiceForBharat Edition) challenge. The agent uses Deepgram for speech-to-text, Google Gemini for language processing, Murf Falcon for text-to-speech, and the LiveKit Agents framework for real-time transport, with support for native scripts and an analytics dashboard.

Over the past ten days, I took part in the 10 Days of AI Voice Agents VoiceForBharat Edition challenge. The goal was simple yet ambitious: build a production-ready, highly responsive voice agent tailored for Indian users from scratch. Throughout this journey, every single voice component was powered by Murf Falcon, the fastest TTS API, using expressive and natural voices like Anisha, Samar, and Pooja. Here is the complete story of what I built, the hurdles I faced, and how you can build your own. . Who it is for: Indian users seeking instant, natural, and localized voice assistance in their native language scripts. . Why Voice? Voice removes literacy barriers, making technology instantly accessible, conversational, and intuitive for everyday users. .Multilocale & Native Script Compliance: Configured Deepgram STT language="multi" and enforced strict prompt guidelines so the LLM responds in native scripts e.g., Hindi in Devanagari like नमस्ते instead of romanized text . . Advanced Capabilities: Equipped the agent with memory for returning users, custom tools for fetching data, automated outbound calling, human escalation/hand-offs, and specialist agent routing. . Analytics Dashboard: Built a tracking backend using Python, SQLite, and Chart.js to monitor call metrics and outcomes. -What I Tried & The Fix: Initially, I checked my port bindings and routing rules. After debugging the Flask application structure and ensuring proper template rendering paths, I cleared the local port conflict and successfully re-hosted the SQLite-backed analytics dashboard, bringing the entire monitoring system online. 1.Speech-to-Text STT : Deepgram configured for multi-language detection . 2.LLM: Google Gemini for processing logic and conversation flow . 3.Text-to-Speech TTS : Murf Falcon for low-latency, hyper-realistic voice output . 4.Real-Time Transport: LiveKit Agents framework. python import logging from dotenv import load dotenv from livekit.agents import JobContext, WorkerOptions, cli from livekit.agents.multimodal import MultilingualModel from livekit.agents.voice import AgentSession from livekit.plugins import deepgram, google, murf, silero, tokenize load dotenv logger = logging.getLogger "voice-agent" async def entrypoint ctx: JobContext : vad = silero.VAD.load system prompt = "You are a helpful voice assistant.
