| Abstract: | Language identification technology is a very important part of the speech recognition technology.In this paper,based on the practical application and a self-established voice database,a language identification system based on the GMM-UBM model and independent of the speaker is studied and compared with the traditional GMM methods.Experiment results show that this algorithm can effectively improve the performance of the language identification system and achieve an average recognition rate of 74%. |
