摘要

Consideration is given to calculating and coding the parameters of vocoders operating at speed of 1200 and 2400 bps. The efficient methods for calculating and coding the parameters of the autoregressive speech signal model such as line spectral frequencies and the pitch period are proposed. The works on computation optimization allowed a vocoder to be implemented in real time on the signal processor ADSP-2191.
