Abstract

Publication compares different local operators working in specral domain for speech recognition with the use of temporal trajectories (TRAP) technique. The evaluation is done on digits recognition task.

Annotation

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.
