    Undertermined Blind Source Separation Using Linear Separation System

  • Original language description

    In automatic speech recognition and speech modal analysis, good quality of input speech signal is often required. The hit rate of recognizers is lowered by degradation of speech quality due to the noise. Blind source separation can be used to enhance thespeech signal as a part of preprocessing techniques. This paper presents a multi channel linear blind source separation method that can be applied even in underdetermined case (UDC) i.e. when the number of source signals is higher than the number of sensors. The experiments show that our system outperforms conventional time-frequency binary masking (TFBM) in both determined and underdetermined cases.

    Nedourčená slepá separace zdrojů pomocí lineárního separačmního systému

  • Czech description

    V automatických systémech zpracování řeči je často vyžadována její dobrá kvalita. Úspěšnost rozpoznávačů je snižována, když vstupní řeč obsahuje šum. Článek uvádí vícekanálovou metodu slepé separace pro nedourčený případ (UDC), tj. když počet zdrojovýchsignálů je vyšší než počet senzorů.
