Evaluation of Blind Separated Signals Using Speech Recognition System
Original language description
Output blind separated signals are recovered independent sources obtained from their mixtures using methods of convolutive independent component analysis. These methods have no information about the original sources and the mixing process. For the separation process we adapted and improved a method which is based on the natural gradient approach. The new concept proposed in this paper then tries to measure the hit rate of the source restoration by means of the discrete word intelligibility using an Inteernet speech recognition system. We are interested in a two-channel case, in which we observe the outputs of a 2 x 2 linear time invariant system of mixtures of speech, music and noise signals.

Vyhodnocovani sgnalu separovanych naslepo pomoci recoveho rozpoznavaciho systemu
Czech description
Vystupni signaly separovane naslepo jsou obnovene nezavisle zdroje ziskane z jejich smesi pomoci metod konvolucni analyzy nezavislych komponent. Tyto metody nemaji zadnou informaci o puvodnich zdrojich a smesnem procesu. Pro separacni proces jsme upravili a vylepsili metodu, ktera je zalozena na prirozenem gradientu. Novy postup prezentovany v tomto prispevku se pak snazi 'merit' uspesnost obnoveni zdroju vyhodnocovanim srozumitelnosti jednotlivych slov promluvy pomoci Internetoveho rozpoznavaciho systeemu. Zajima nas casove invariantni system dvou pozorovanyh smesi reci, hudby a sumu.
