Abstract
Parameters are received that include prediction coefficients representing a speech spectral envelope characteristic, impulse positions of an excitation signal, and zero filter coefficients which provide a sequence of impulses with a shape resembling a phase-equalized residual of a speech. An impulse sequence generator produces a sequence of impulses having the impulse positions, which are fed into a zero filter. The zero filter provides, under control of the zero filter coefficients, the sequence of impulses with a shape resembling a phase-equalized residual of the speech. The output of the zero filter is fed as an excitation signal into an all-pole filter which is controlled by the prediction coefficients to produce a synthesized speech.
