| contents | Speech Enhancement with Local Adaptive Rank-Order Filtering Vitaly Kober Victor Diaz Ramirez Yuma Sandoval Ibarra Computación rank musical noise intelligibility order statistics Speech enhancement A local adaptive algorithm for speech enhancement is presented. The algorithm is based on calculation of the rank-order statistics of an input speech signal over a moving window. The algorithm varies the size and contents of a sliding window signal as well as an estimation function employed for recovering a clean speech signal from a noisy signal. The algorithm improves the quality of a speech signal preserving its intelligibility. The performance of the algorithm for suppressing additive noise in an input test speech signal is compared with that of common speech enhancement algorithms in terms of objective metrics. 2014 artículo científico 1405-5546 https://www.redalyc.org/articulo.oa?id=61530484010 en http://www.redalyc.org/revista.oa?id=615 Computación y Sistemas application/pdf Instituto Politécnico Nacional Computación y Sistemas (México) Num.1 Vol.18 |
