Abstract
The speech coding apparatus comprises a memory to store the convolution data of a pitch reproduced excitation pulse sequence extracted from an excitation pulse sequence in the pitch reproduction processing with a coefficient of linear predictive synthesis filter. When the convolution processing is repeated again, the speech apparatus performs the memory control to write a part of the previous convolution data in a storing area of current convolution data, then performs the pitch prediction processing using the current convolution data.
