ABSTRACT:
A speech synthesizer includes a lattice-type multi-stage digital filter modified in the next to last stage thereof by incorporating an increasing circuit for slightly effectively increasing the absolute value of a parameter K.sub.2 so as to reduce an attenuation factor. The device is useful for generating tones of a sustained quality, such as musical tones.
