Description
  • In the paper two contributions to silence detection problematics are described. The first contribution is a classifier based on decision graphs construction. Furthermore we performed the Independent Component Analysis on MFCC parameterization of used speech corpus and evaluated the influence of this method on voice activity detection accuracy. For experiments we used the decision graphs and HMM based classifier.

  • V práci jsou popsány dva příspěvky do problematiky detekce řeči a ticha. Prvním příspěvkem je klasifikátor založený na rozhodovacích grafech. Navíc byla provedena analýza nezávislých komponent na MFCC parametrizaci použitého řečového korpusu a následně byl vyhodnocen vliv této analýzy na přesnost detekce. V experimentech byl použit jednak detektor založený na rozhodovacích grafech a jednak HMM klasifkátor. (cs)
