Abstract :
Personal digital assistant (PDA) is more and more popular due to its powerful functions. To protect the personal information of PDA, we adopt the technology of text-independent speaker verification (SV) for this kind of embedded system. In this paper, Gaussian mixture model (GMM) and universal background model (UBM) are addressed in detail. The optimization of mathematical computation of GMM-UBM guarantees the real-time performance of our SV system.
