Order-Variable Multi-Pulses Linear Prediction Speech Coding
On the base of all-poles model, this paper provides order-variable all-poles model according to instability of track complexity and applies this model in Multi-pulses linear prediction speech coding. This method is simulated in Matlab and quality of synthesized speech is evaluated, order-variable model is founded to keep better speech quality on the base of decreasing coding rates.
