| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Generally, short utterance test data seriously degrades the accuracy of speaker verification. However, in many voice-operated systems, utterances with a length of less than a few seconds are often used in practice and it is concerned that the accuracy is degraded. In this paper, we focus on short utterances of just a few words as the practical problem and propose a rank-based verification method with i-vector. This method used 3,268 speakers for ranking and compared with conventional method with scoring. The experimental results show the improvement when using rank-based method. Moreover, we investigate the effect of improvement by changing the construction of speakers for ranking. | |
