This paper addresses the escalating challenges posed by deepfake attacks on Automatic Speaker Verification (ASV) systems. We present a novel Urdu deepfake audio dataset for deepfake detection, focusing on two spoofing attacks – Tacotron and VITS TTS.

This work hypothesizes whether ASV systems can be fooled by deepfake speech generated on African accents. Prior studies primarily concentrated on native English speakers. This research centers on African English speakers who frequently interact with digital systems. Experiments assessed a selected DNN-based deepfake audio system and an ASV system, demonstrating that ASV systems are less susceptible to deepfake audio deception in African accents.

This work introduces a neural network method to develop a classifier that will blindly classify an input audio as real or mimicked; the word ’blindly’ refers to the ability to detect mimicked audio without references or real sources.

This study addresses the threat of identity theft in automatic speech verification systems using a Cyclic GAN-based model to generate and detect spoofed voices, specifically focusing on Urdu and English speech datasets. By leveraging adversarial examples for spoof detection and using Gradient Boosting to differentiate real from fake voices, the approach shows promise but requires further data and refinement for practical large-scale implementation.
