| Abstract(in English) | In this paper, the combinations of speech enhancement techniques are experimented. Specifically, the spectral subtraction, KLT based comb-filtering, and their combinations are applied to the Aurora2 database, and their results are compared. The results show that the performance is improved in the recognition accuracy when KLT based comb-filtering was applied after spectral subtraction. |
