Abstract(in English) | Many conventional speech noise removal methods are performed by time invariant filtering. However, the speech signal is consisted of two sections, one is voice section, the other is non-voice section. These two sections are demanded to different methodology each other. In this paper, we propose the data-dependent filtering for removing the additive noise from speech signal. The data-dependent filtering realizes the noise removing sufficiently in non-voice section, while preserving the speech signal in voice section. We show the effectiveness of the proposed method compared to the conventional method. |
