Abstract

This research aims to distinguish between real human voices and synthesized voices in order to prevent crime resulting from voice impersonation using deepfake voice technology. There have been cases where energy companies were scammed out of nearly £200,000 (USD 260,000) after criminals used deepfake voice technology to imitate the CEO's voice and approve payment. For the dataset used in this research, 15 famous individuals’ voices were recorded and divided into three sets: a training set, a validation set, and a testing set, with a ratio of 75:15:10. The Mel-frequency cepstral coefficients (MFCC) were extracted as the features of the voices and a convolutional neural network (CNN) was used to classify the voices. The performance of the model was evaluated using a confusion matrix, and the accuracy was found to be 97%.
