How I built a free AI voice detector that supports 5 Indian languages

I'm a 2nd year ECE student at KIT, Tamil Nadu.
I just shipped VoiceID — a free tool that detects
whether a voice is human or AI-generated.

The Problem

Deepfake audio is becoming a real threat. Most detection
tools only support English. Nobody was building for
Indian languages.

What I Built

VoiceID analyses 88 acoustic features from any MP3 or
WAV file and classifies the voice as Human or AI with
a confidence score.

Supports: English, Tamil, Hindi, Malayalam, Telugu.

Live demo: https://mdeepaksai.github.io/human-or-AI/

Tech Stack

  • FastAPI backend deployed on Railway
  • Vanilla JS frontend on GitHub Pages
  • Supabase for live visitor tracking

What I Learned

Shipping a real product is completely different from
building a college project. You deal with CORS issues,
file size limits, audio format compatibility, and
latency that you never think about in a demo.

The most valuable thing wasn't the ML model.
It was deploying something real people actually use.
