Abstract:
     A gradually attenuative non-linear processor system for speech synthesizer is composed of an adaptive filter for convolving the speech signal and pulse response of terminal A to generate simulative echo, an echo eliminator for subtracting the simulative echo from the speech signal of terminal B to eliminate echo, a residual echo amplitude judging unit, and a gradually attenuative non-linear process for processing the residual echo signal if its amplitude is lower than threshold.
