Speaker identification based on Gaussian mixture model (GMM) has achieved good performance in practical applications. However its processing speed is very slow, which greatly affects its practicability. In this paper, we propose two methods to tackle this problem. Firstly, the GMM likelihood score formula is converted into linear, and further converted to the dot product of the model. Based on these...
