| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Degenerate Unmixing Estimation Technique(DUET) is one of Blind Source Separation(BSS) methods and can separate sevral speech signals from two mixtures in spite of the number of original sources. However, it is necessary to make the distance of two microphones small for separating several speech signals because the distance constrains sampling frequencies. This paper proposes a new evaluation of phase-delay parameters to be used for creating a histgram to overcome such a problem. The parameters are evaluated from unwrapped group-delay ones which obtained by a procedure without calculating phase angles. |
