Efficient implementation of joint optimization of excitation and model parameters in multipulse speech coders |
摘要 |
An efficient optimization algorithm is provided for multipulse speech coding systems. The efficient algorithm performs computations using the contribution of the non-zero pulses of the excitation function and not the zeroes of the excitation function. Accordingly, efficiency improvements of 87% to 99% are possible with the efficient optimization algorithm. <IMAGE>
