Voice Biometrics: Speaker Verification and Identification

A Method for the Real-Time Updating of Voice Samples in the Unified Biometric System

“…Hence, a speech signal from the given speaker x k (t) with a duration T k = (2, ..., 3)R × J k, r × τ = (1.2, ..., 1.8)R can be regarded as suffi cient for the formation of the PDB X k . In particular, in the case of application of six vowel phonemes of the Russian language, we get T k = 8-10 s, which is in good agreement with the possibilities of contemporary methods aimed at the automatic processing of speech [3,15].…”

“…A powerful impetus to the creation and implementation of the UBS was given by the national program "Digital Economy of the Russian Federation" approved by the Russian government (https:// digital.gov.ru/ru/activity/directions/858/). According to the claimed purposes of this program and the existing worldwide trends, the UBS must penetrate, in the future, into almost all spheres of the national economy: from health protection and education to the systems of online state services [1][2][3]. However, in the fi rst stage, the priority is given to the sphere of banking because the application of UBS may signifi cantly increase the possibility of getting remote bank services, including telephone requests, and, hence, sharply increase the bank traffi c [4].…”
