Improved Wiener Filter Algorithm for Speech Enhancement

Abstract: Most of the existing speech enhancement algorithms are aimed at improving the quality of speech, and the algorithms that can improve the speech intelligibility effectively are rare. Speech intelligibility has been found to improve listening comfort and it is generally related to the distortion of the speech signal closely. Studies have assessed the impact of speech distortion introduced by gain functions and shown that one of the main reasons that existing algorithms cannot improve speech intelligibility is be… Show more

“…Turget's work [29] focused on removing any distracting sounds from collected baby crying sounds and emphasizing speci ic points during the preprocessing stage. This pre-emphasis can done using spectral subtraction, Wiener iltering, and adaptive iltering [30,31]. The goal is to improve the Signal-to-Noise Ratio (SNR) of the sound ile.…”
