摘      要：This paper studies a high-speed text-independent Automatic Speaker Recognition(ASR)algorithm based on a multicore system s Gaussian Mixture Model(GMM).The high speech is achieved using parallel implementation of the feature s extraction and aggregation methods during training and testing *** memory parallel programming techniques using both OpenMP and PThreads libraries are developed to accelerate the code and improve the performance of the ASR *** experimental results show speed-up improvements of around 3.2 on a personal laptop with Intel i5-6300HQ(2.3 GHz,four cores without hyper-threading,and 8 GB of RAM).In addition,a remarkable 100%speaker recognition accuracy is achieved.
