Abstract :
We consider mimicry, a simple technology form of attack requiring a low level of expertise, to investigate whether a speaker recognition system is vulnerable to mimicry by an impostor without using the assistance of any other technologies. Experiments on 138 speakers in the YOHO database and two people who played a role as imitators have shown that an impostor can attack the system if that impostor knows a registered speaker in the database who has very similar voice to the impostor´s voice.
