Came across this absolute gem yesterday! Published by McGraw-Hill 1985. Here is the blurb on the back…
“Talking computers? This book tells you how to make it happen for under $35 to your Apple II, IIplus and IIe; TSR-80 I, III and IV; Commodore 64 and Vic 20; Sinclair ZX80 and ZX81; and Timex/Sinclair 1000 Computers.
How To Make Your Computer Talk describes how complex speech waveforms are electronically modeled, enabling designers to put a digital model of the human vocal tract, a controller, and speech data on silicon. It provides you with complete, detailed instructions on interfacing speech hardware to the above mentioned machines.
Explore this exciting new dimension in computing and invent on your own, with these expert instructions. Examples of software that illustrate fundamental principles are included as an introduction to speech synthesis using your home computer.
Steven J. Veltri is Vice president of Research in Speech Technology and was formerly a product marketing engineer for the speech synthesis product lines of General Instruments Corporation.”
