COMPARISON OF DIGITAL SIGNAL PROCESSING METHODS AND DEEP LEARNING MODELS IN VOICE AUTHENTICATION

This paper addresses the issues of traditional authentication methods, such as the use of passwords, which often prove to be unreliable due to various vulnerabilities. The main drawbacks of these methods include the loss or theft of passwords, their weak resistance to various types of attacks, and the complexity of password management, especially in large systems. Biometric authentication methods, particularly those based on physical characteristics such as voice, present a promising alternative as they offer a higher level of security and user convenience. Biometric authentication systems have advantages over traditional methods because the voice is a unique characteristic for each person, making it substantially more challenging to forge or steal. However, there are challenges regarding the accuracy and reliability of such systems. Specifically, voice biometric systems can encounter issues related to changes in voice due to health, emotional state, or the surrounding environment. The primary objective of this paper is to compare contemporary deep learning models with traditional digital signal processing methods used for speaker recognition. For this study, text-dependent methods
