Temporal decomposition for low rate wideband speechcompression
Christian H. Ritz, Lee Burnett · Electronics Letters · 2001
An investigation into low bit rate wideband speech coding for applications such as unicast streaming is presented. Wideband spectral parameters are quantised below 1 kbit/s using temporal decomposition (TD) applied to the line spectral frequencies. Quantisation using TD performs significantly better than split vector quantisation at an equivalent bit rate.
