Abstract
A circuit for electronically synthesizing speech has an audio generator for representing voiced sounds and a noise generator for representing voiceless sounds and a means for selecting significant parameters of the various speech elements by sampling and a means for storing those parameters. The circuit also includes a filter unit comprised of a number of individual filters and a means for selectively driving only those individual filters having filter coefficients necessary for representing the significant parameters of the particular speech element to be synthesized. The filters can be utilized individually or combined into selected groups in order to generate longer speech segments. The electronic signal at the output of the filter unit is edited for acoustically reproducing the desired speech elements and segments.
