English Abstract

In this paper, We introduced a speaker clustering algorithm in speech recognition, which includes its effect to the recognition system. Also, its usage, the features used, distance measurement and the procedure of the algorithm were de scribed. To evaluate the effectiveness of the algorithm, we do two kinds of experiments. One is by calculating the clustering correction rate directly and the other is by comparing the word error rate (WER) of the recognition system under two different conditions: whether using the speaker clustering algorithm or not. From the experiments, we can see that the sentence clustering correction rate is reached 85.69% when using the GLR distance measurement. In the recognition experiment, the performance of the system improves a lot, that the word error rate is very near that of the system by using the known speaker information to do the speaker adaptation.
