CONF valente:icslp:2006a/IDIAP Discriminant linear processing of time-frequency plane Valente, Fabio Hermansky, Hynek EXTERNAL http://publications.idiap.ch/attachments/papers/2006/valente-icslp-2006.pdf PUBLIC http://publications.idiap.ch/index.php/publications/showcite/valente:rr06-20 Related documents International Conference on Spoken Language Processing 2006 IDIAP-RR 06-20 Extending previous works done on considerably smaller data sets, the paper studies linear discriminant analysis of about 30 hours of phoneme-labeled speech data in the time-frequency domain. Analysis is carried both independently in time and frequency and jointly. Data driven spectral basis show similar frequency sensitivity as human hearing. LDA-derived temporal FIR filters are consistent with temporal lateral inhibition. Considerable improvement is obtained using first temporal discriminant.
