Abstract

A speech synthesizer including a device for storing compressed digital signals corresponding to original information speech or audio waveform time domain signals, the digital signals including information signal portions and instruction signal portions identifying particular compression techniques applied to associated information signal portions; an output terminal for manifesting analog electrical synthesized signals corresponding to the original signals; a digital-to-analog converter having an output coupled to the output terminal and an input; and an intermediate signal processing circuit having an input coupled to the storage device and an output coupled to the digital-to-analog converter for expanding the information signal portions in accordance with the instruction signal portions to produce digital synthesized signals to be converted to analog synthesized signals by the digital-to-analog converter.
