Method and apparatus for speech synthesizing
First Claim
1. A speech synthesizer comprising:
- means for storing compressed digital signals corresponding to original information speech or other audio wave form time domain signals, said digital signals including information signals portions and instructions signals portions identifying particular compression techniques applied to associated information signal portions;
means for manifesting analog electrical synthesized signals corresponding to said original signals;
digital-to-analog converter means having an output coupled to said manifesting means, and an input; and
intermediate signal processing means having an input means coupled to said storing means for receiving said information portions and said instruction signal portions of said digital signals stored in said storing means, and an output means coupled to said digital-to-analog converter means, for expanding said information signal portions in accordance with said instruction signal portions to produce digital synthesized signals to be converted to said analog synthesized signals by said digital-to-analog converter means.

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.
