This paper examines the method of spoofing text-dependent voice verification systems based on the most popular TTS approaches: Unit Selection and HMM. Research of this method shows the possibility of achieving a false acceptance error of 98%-100% if the duration of the TTS database is sufficiently large. A distinctive feature of the method is that it can be fully automatical if used in conjunction with a speech recognition system.
