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.}, pdf = {https://publications.idiap.ch/attachments/reports/2006/valente-idiap-rr-06-20.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2006/valente-idiap-rr-06-20.ps.gz}, ipdmembership={speech}, }
