Resumen
AI technologies, which have received an impetus in development in recent years due to the emergence of a significant amount of data and computing resources, have greatly influenced many areas of human life, and for some of them, they have become an integral part. It is worth noting separately the emergence of various means of biometric user identification, which today have found their application in generalpurpose systems and critical ones. Such tools include biometric user identification by fingerprint, face, voice, iris, hand geometry, etc. We use these tools daily in our everyday life when we use smartphones, personal computers, or interact with banks, which have begun to use biometric identification tools when interacting with customers widely. Thus, the reliability of biometric identification of users becomes undoubtedly important and requires due attention from information security specialists. Since these systems are usually based on ML models, their resistance to external influences plays a key role. In this paper, we presented an approach to automatically increasing the stability of ML models to external influences, using the example of the speaker identification problem by voice.
