Abstract
This invention provides a novel speech coding system which recursively executes a filter-applied Toeplitz characteristic by causing a drive signal (i.e. an excitation signal) to be converted into a Toeplitz matrix when detecting a pitch period in which distortion of the input vector and the vector subsequent to the application of filter-applied computation to the drive signal vector in the pitch forecast called either closed loop or compatible code book is minimized. The vector quantization method substantially making up the speech coding system of the invention is characteristically used by the system.
