Adaptive-width approximation of events in temporaldecomposition based speech coding
Shahrokh Ghaemmaghami, Mohamed A. Deriche · Electronics Letters · 1996
Temporal decomposition (TD) is used to compress speech spectral information in very low-rate coding. The authors have shown earlier that further compression of such information is achieved by approximation of speech ‘events’ using fixed-width simple functions. A new technique is introduced to improve event approximation performance using ‘variable-width’ composite functions.
