| Abstract(in English) | Non-linguistic features such as vocal tract shapes and acoustic devices are inevitably involved in speech. Recently, a new representation of speech without any dimensions indicating the non-linguistic features was proposed. It discards the absolute properties of speech events and captures only the interrelations among them. In this paper, first, analysis experiments of the representation in noise were conducted. The results showed that though additive noise distorts the representation, it can remove much of speaker individuality by modifying the upper-band spectrum to be uniform. In the next, recognition experiments of Japanese vowel sequences in noise were done. The results showed that the proposed method trained from a single speaker in the matched condition can outperform the conventional method trained from 4,130 speakers with SS and CMN. |
