ABSTRACT:
A speech recognition apparatus includes a feature extraction section, and a recognition section. The feature extraction section extracts the feature vectors of input speech. The feature extraction section includes at least a pitch intensity extraction section. The pitch intensity extraction section extracts the intensities of the fundamental frequency components of the input speech. The recognition section performs speech recognition by using the feature vectors from the feature extraction section.
