| Outline of Final Research Achievements |
In this study, I evaluated the accuracy of speech higher-ordrer statistics estimation in various environments. Also I inspected the efficacy of speech higher-order statistics estimation with the assumption that the complex spectra obey the generalized gaussian distribution.
From the objective evaluation, I confirm that the proposed method can estimate the higher-order statistics with high accuracy in each noise environment.
