Statistic evaluation of various speech parameters for phonemes in Slovak language

In the following paper we present statistic information of parameters of speech units. Some parameters provide ability to distinguish phonemes to groups. We try to find feature which can do this separation and can be used in our next research. For data extraction we used SKK2 database of clear speech. Analysis was focused on phonemes and their parameters like energy, zero-crossing rate, MFCC, PLP, etc. Tables in paper demonstrate options of separation to groups from several views.
