Votrax

[4][5] It remained Votrax inc. until about 1992, when it was renamed to or otherwise merged with Vysion, Inc., a maker of security cameras and other related devices.

[6] In 1984, Votrax either declared bankruptcy or came close to doing so, and restructured itself as a commercial phone-interface provider, and hence produced no new consumer products.

Votrax's speech technology was also used by 3rd parties in several arcade games, Gottlieb System 80 pinball machines, and talking terminals.

[13] A Votrax synthesizer was used as part of the text-to-speech subsystem of the first generation Kurzweil Reading Machine for the Blind.

During the 1970s, Votrax produced a series of discrete speech synthesizers, with epoxy-coated boards to thwart people copying their designs.

[15] Since early in its life, Votrax specialized in making phoneme-based speech synthesizers and text-to-speech algorithms.

[20] Details of the algorithm were later (1974) described in his paper "Synthetic English speech by rule", Bell Telephone Laboratories Computer Science Technical Report #14, which is available on his personal site's publications page.

[21] The most typical commercial products are two boxes named "Type 'N Talk (TNT)" and "Personal Speech System (PSS)".
