| Abstract(in English) | We describe that speech enhancement for natural and multi speaker dialognue. To record natural and multi speaker dialognue, we focus on utterances in the werewolf game JINRO which is one of the speech communication based card game. As we think that player’s utterance while they play with JINRO is natural, we record their dialognue and analyise it. We propose NMF based speech enhancement method to enhance one of the speakers. AfterselectingspeechsegmentofthetargetspeakerandanalysingbyNMF,his/hercharactoristicrepresentsasbase vectors. Multi speaker dialognue is analyised by NMF with the speaker’s base vectors and new base vectors. After all, noise’s and other speaker’s charactoristics are estimated in the new base vectors. The idea is that the given the speaker’s base vectors are ?xed in matrix factorization procedure. We can get activation matrix in which each line is divided into target speaker and the others. By using target speakers activities, we can synthesize enhanced speech. We conducted an experiment by 7 players, but the proposed method did not show good performance. The reason is that it is hard to get only the target speaker’s base vectors. |
