Abstract
Most current research on deepfake voice detection focuses heavily on English or Mandarin, creating a significant security gap for Hindi speakers. To address this, we developed a detection framework specifically tailored for the Hindi language using a lightweight approach: Mel-Frequency Cepstral Coefficient (MFCC) feature extraction paired with an XGBoost classifier. We trained the system on a large dataset comprising over 99,000 real voice samples and roughly 3,800 synthetic samples, each clipped to a duration of 5–8 seconds. The model proved highly effective against standard text-to-speech (TTS) audio, achieving 99.99% accuracy with perfect precision and recall scores on our test set. We further stress- tested the system by introducing background noise; even at a high noise level (5dB SNR), the model maintained a robust 88% accuracy. However, we discovered a key limitation: while the model easily flags standard TTS deepfakes, it struggles to distinguish hyper- realistic clones generated by advanced tools like ElevenLabs. This study establishes a crucial baseline for Hindi audio forensics while highlighting that future work must evolve beyond classical features to counter high-fidelity AI generation.
