On Extending VTLN to Phoneme-specific Warping in Automatic Speech Recognition
2009 (English)In: Proceedings of Fonetik 2009, 2009Conference paper (Other academic)
Phoneme- and formant-specific warping hasbeen shown to decrease formant and cepstralmismatch. These findings have not yet been fullyimplemented in speech recognition. This paperdiscusses a few reasons how this can be. A smallexperimental study is also included where phoneme-independent warping is extended towardsphoneme-specific warping. The results of thisinvestigation did not show a significant decreasein error rate during recognition. This isalso in line with earlier experiments of methodsdiscussed in the paper.
