| Abstract(in English) | In this paper, we conducted a speaker verification experiment using large-scale speech database maintained by National Research Institute of Police Science, Japan. In this experiment, we used speech data of 664 people collected by a capacitor microphone and a bone-conducted microphone. From experimental results, we confirmed that our proposed method that uses rank information obtained by multiple speaker model in previous work improved verification performance than a conventional method using T-norm score. In addition, we compared the speaker model based on GMMs and that based on VQ centroids. From this comparison, we can see that the speaker model based on VQ centroids is higher performance than that based on GMMs under the condition of the capacitor microphone speech. However, VQ centroids degraded the performance of that based on GMMs under the condition of the bone-conducted speech. Moreover, the performances of the bone-conducted speech significant degraded performance if there were difference of the speaking session between the registration and the testing. |
