Inspiration

Millions of Indians lack internet access but own mobile phones. I wanted to bridge this gap using voice AI — no internet, just a phone call.

What it does

NoxSevaBot is a voice-based AI assistant that lets anyone call a number and ask questions. It supports English and can be extended to Hindi/Telugu. It replies intelligently via phone using Groq API.

How we built it

Python with Flask for the backend

• Twilio for phone call integration
• Groq API for AI responses
• Deployed using Render cloud platform
• Used GitHub for version control and collaboration

Challenges we ran into

• Groq API key exposure (learned to use .env and .gitignore)
• Memory limits on Render
• Twilio only providing US numbers on trial account
• Making speech recognition work reliably over phone

Accomplishments that we're proud of

Built a fully working voice bot that talks back using AI

• Deployed it and made it globally accessible via phone
• Cleaned up dependencies and improved app performance
• Used ping bots to keep the project awake

What we learned

Secure API management

• How to integrate Flask + Twilio
• Deploying apps on Render with custom ports
• Using GitHub professionally

What's next for nox seva bot

Add multilingual voice support (Hindi, Telugu)

• Get an Indian Twilio number (paid)
• Add interrupt option during call
• Improve response speed and error handling
