Recent Advancements in Speech Enhancement

چکیده
Speech enhancement is a long standing problem with numerous applications ranging from hearing aids, to coding and automatic recognition of speech signals. In this survey paper we focus on enhancement from a single microphone, and assume that the noise is additive and statistically independent of the signal. We present the principles that guide researchers working in this area, and provide a detailed design example. The example focuses on minimum mean square error estimation of the clean signal’s log-spectral magnitude. This approach has attracted significant attention in the past twenty years. We also describe the principles of a Monte-Carlo simulation approach for speech enhancement.

A Novel Frequency Domain Linearly Constrained Minimum Variance Filter for Speech Enhancement
A reliable speech enhancement method is important for speech applications as a pre-processing step to improve their overall performance. In this paper, we propose a novel frequency domain method for single channel speech enhancement. Conventional frequency domain methods usually neglect the correlation between neighboring time-frequency components of the signals. In the proposed method, we take...
