A computationally efficient stochastic vector quantisation (VQ) scheme for the quantisation of the LPC parameters with less than 25 bits is proposed. The complexity of the self-excited vocoder (SEV) is reduced by employing fast algorithms based on an efficient representation of the innovation sequence. When deploying the suggested VQ scheme in the improved SEV, good communications speech quality has been resulted at 4.8 Kb/s. When the bit rate is increased to 6.8 Kb/s, near-toll quality speech has been achieved.
