LibraAI

An AI voice-emergency assistant! Won 4th place at Hack 'N' Tackle hackathon.

To train custom voice model, run the notebook at https://github.com/ashwin2k/wake-word-detection

What does it do?

• LibraAI uses a GRU based model top detect the pretrained wake word "help me" from the user.
• It uses a persistent notification that actually serves 2 functions:
  1. A Quick Access Notification bar to access the help functions directly
  2. To actively listen for the trigger word even when the phone is in sleep mode or the app is closed.
• When the trigger word is detected:
  1. The flashlight is flashed in an SOS manner
  2. The emergency contacts are notified
  3. The police helpline is called.

To run the app
