In This Issue

This month we talk about voices - computer voices, that is - and several other topics as well. Consulting Editor Mark Dahmke speaks out on speech in the editorial "Computer Speech: An Update." We also have two theme articles: "An Extremely Low-Cost Computer Voice Response System," which shows how to computerize your vox humana for very little money, and "Articulate Automata," which looks at the physiology of speech.

Also in this issue is Steve Ciarcia's do-it-yourself computerized Big Trak; everything you've always wanted to know about dynamic memory; inexpensive AID and D/A conversion; and much more, including reviews of the new Radio Shack Daisy Wheel Printer II, the Heath H-14 printer, not to mention Zork and IRV.
