With the popularity of the mobile terminals, identity authentication for the mobile terminal applications has become a key issue in protecting the security of the mobile terminal information. The voiceprint recognition technology has broad application prospects because of its flexible, economical and practical advantages. This paper describes the realization of the voiceprint identity authentication system for Android mobile terminal in detail, including the design of the voiceprint registration module and the design of the voiceprint recognition module. In order to solve the problem that the training sample data generalization ability is not high, this paper presents a training and recognition method of voiceprint model combined with stacking and cross validation. Finally, the performance of the system is tested. The experimental results show that the system has better authentication ability.
