Direct recognition of phonemes in speaker independent recognition systems still cannot guarantee good enough recognition results. Here we want to investigate assumption that recognition could be improved via group features of phonemic system. We propose to try to recognize group of phoneme first (voiced/unvoiced, vowel/ con-sonant, etc.) then try to recognize phoneme itself. In this experiment a system for discrimination of fricative consonants and sonants was developed using phonetic – acoustic features.
