| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we present an approach of recovering signal waveforms of speech sources from observed signals in noisy and reverberant environments. The new BSS is a multistage BSS approach in a cascade of the Diagonalization implemented by Mini mizing the Direct and Indirect least-squares criteria (DMDI) algorithm followed by the Alternate Jacobi Algorithm (ALUJA). At the first stage, the DMDI algorithm is good at convolutive BSS in long reverberant environments. At the second stage, ALUJA is good at BSS with a large number of sources. Simulation results are given for separation performances of the multistage BSS in noisy and long reverberant environments. |
