Voice biometrics for user authentication is a task in which the object is to perform convenient, robust and secure authentication of speakers. Recently we have investigated the use of state-of-the-art text-independent and text-dependent speaker verification technology for user authentication and obtained satisfactory results within a framework of a proof of technology. However, the use we have made of a quite large development set limits the practical potential of our system. In this work we investigate the ability to build an accurate user authentication system with the limitation of having a small development set.
