AI BASED LIE DETECTOR

Unveiling The Truth

The problem AI BASED LIE DETECTOR solves

Detecting deception is critical in interviews, examinations, and security checks, but existing methods like polygraphs are intrusive, expensive, and unreliable. This project provides a non-intrusive, AI-based solution that analyzes speech features and facial cues to classify responses as Truth, Lie, or Uncertain in real time.

Challenges we ran into

Data Availability: Limited real-world datasets for lies vs truth.

Noise & Variability: Background noise and different accents affect accuracy.

Feature Reliability: Micro-expressions and voice stress can vary across individuals.

Ethical Concerns: Privacy, consent, and risk of misuse.

Model Generalization: Risk of overfitting on small or biased datasets.
