A 2.0 kbps high quality speech coder is presented in the paper. The coding technique is based on the multiband excitation (MBE) model which is efficient in the modelling of speech excitation. The spectral envelope is by linear predictive coding (LPC) The quantization of LPC parameters employs a 2-stage split residual vector quantization (SRVQ) scheme. Performance comparisons with other spectral coding schemes using discrete cosine transform DCT) and two-dimensional differential LSP (2DdLSP) are given.<>
