The identified Volterra kernels reveal the spectro-temporal patterns that are learned by the trained system for each phoneme. To demonstrate the applicability of Volterra series, we analyze a multilayered perceptron trained using Mel filter bank energy features and analyze its first order Volterra kernels.}, pdf = {https://publications.idiap.ch/attachments/reports/2008/Pinto_Idiap-RR-69-2008.pdf} }
