The technique extends earlier works on delta features and RASTA filtering by processing temporal trajectories by a bank of band-pass filters with varying resolutions. In initial tests on OGI Digits database the technique yields about 30\\% relative improvement in word error rate over the conventional PLP features. Since the applied filters have zero-mean impulse responses, the technique is inherently robust to linear distortions.}, pdf = {https://publications.idiap.ch/attachments/reports/2005/rr05-18.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2005/rr05-18.ps.gz}, ipdinar={2005}, ipdmembership={speech}, }
