Originální abstrakt

This paper describes tests with local operators applied to
critical-band speech
spectrum prior to  temporal patterns (TRAPs) feature extraction. Tests
are performed with an  HMM recognizer on connected-digits task. We show
that frequency differentiation, in combination with any other
operator, improves the word-error rate (WER) of TRAP-based
recognizer.
