This paper presents on-line system for discriminating speakers without prior learning of speaker information. This system determines the problem whether the speaker of an utterance detected just now is identical with one of the previous speakers or not, and outputs the speaker indices of each utterance. The processing of proposed speaker discrimination is done as follows. First, we calculate log-power and the number of zero-crossing for each frame of an input speech and select a new utterance. Next, we calculate features of log-power and 12 MFCCs from each speech frame in the utterance. Features in the utterance are clustered by the hierarchical clustering to obtain feature cluster in the current utterance cluster. Finally, the system discriminates speakers by using the distance between the features of the utterance. We conducted experiments by using dialogues by two speakers. As a result, we obtained high discrimination rate of 0.87. |
