Inspiration
I was inspired by how many essential services and AI tools are still internet-bound. I wanted to build something that works for everyone—especially people in India who may not have smartphones or internet access but still deserve intelligent assistance.
What it does
Works on basic mobile phones via phone calls
Supports English, Hindi, and Telugu with key-based language selection
Smart AI responses using Groq LLM
Completely hosted in the cloud, accessible anywhere
Built to be portable, initially developed on a pendrive
How we built it
Backend: Python + Flask
AI Engine: Groq API for fast and powerful language generation
Telephony: Twilio handles phone call interaction and speech input
Deployment: Hosted on Render with environment variables securely managed
Voice I/O: Uses Twilio's built-in speech recognition and TTS
Challenges we ran into
Finding a completely free, fast, and multilingual AI API
Managing memory limits on free cloud services like Render
Deploying without exposing secrets (accidentally leaked an API key 😅)
Ensuring voice recognition is accurate, especially for multilingual inputs
Handling Twilio's free trial limitations with non-Indian numbers
Accomplishments that we're proud of
I created a fully functional, reliable AI voice bot that can serve real people—even those who can’t access the internet. This project is just the beginning, and I'm excited to expand it further!
What we learned
How to integrate LLM APIs in real-world projects
Voice response handling with Twilio
Secure API management with .env and GitHub practices
Deploying and maintaining Flask apps on cloud platforms
Improving AI response speed using Groq over Gemini/OpenAI
What's next for Noxseva-bot
Host it on parmanent server and improve its response style and time and make it available on more languages and bind it with Indian number
🛠️ Accessing the Voice Bot: The NoxSevaBot voice assistant is deployed and available via a Twilio number. To protect against spam and misuse, we are not posting the number publicly.
Judges or reviewers who wish to test the bot can contact us through Devpost or email for the number.
Alternatively, please watch the demo video for a full walkthrough of how it works in real-time.
