In this study, we thoroughly examined every component of speaker authentication, analyzing the input, process, and output phases to identify flaws and new threats. Our investigation is organized around specific research topics that aim to effectively address and minimize the identified dangers. By methodically exploring each component of the speaker authentication process, we not only identify possible issues but also recommend proactive methods to protect these systems from unauthorized access. Our research questions act as significant probes, allowing for a deeper knowledge of the underlying difficulties and leading to the creation of tailored authentication solutions. This study goes beyond theoretical analysis and provides practical insights and strategic recommendations for improving the security and reliability of speaker authentication systems in a variety of sectors, including cybersecurity and forensic analysis. We highlight the interrelated nature of the input, process, and output stages, emphasizing the importance of remaining vigilant in the face of emerging security risks. Our goal is to provide the necessary knowledge and tools to effectively handle the complexities of speaker authentication in the changing digital world. This work establishes a solid foundation for the development of safe and durable speaker authentication methods.
