Texas Instruments’ first blockbuster electronic educational toy was the 1976 Little Professor, a reverse calculator that gave simple math equations to solve. When the company decided to make a spelling toy next, engineers knew it had to say the words aloud but also be solid-state: no pull strings. Computer speech synthesis was in its infancy, and the notion that it could be affordable and portable was science fiction. But TI figured out how to turn a recorded human voice into data that the machine recreated electronically. It was the first time most people had heard solid-state speech.[1]

Speak & Spell was a primitive forerunner of AI, teaching children to interact with a computer that responded and corrected—although it had a limited vocabulary of 200 words, and it couldn’t say an arbitrary word typed into it. But did it teach? A 1982 study found no lasting improvement in spelling for children who used it, and spelling teachers bemoaned the loss of history, patterns, phonics—how the elegant mechanics of our language, the sounds in our ears matching the letters on the page, were reduced to mere automated drill.[2]

It did have unintended educational value for tinkerers, hackers, and experimental musicians who opened it up—just like E.T. in the movie—“circuit bending” its innards to make other sounds. Today the Speak & Spell seems crude; we talk all the time to machines that appear to understand us and talk back.

[1] After Speak & Spell, nine engineers defected from Texas Instruments to Voice Control Systems (VCS), a start-up founded in 1979 by Bill Bates, a Dallas real estate developer who was about to serve ten months in prison on a drug-smuggling charge. VCS directly competed with TI on the new holy grail, computer speech recognition. There’s a great 1986 article by Skip Hollandsworth from D Magazine that narrates the human drama behind a criminal case over stolen trade secrets. The sums of money seem quaint; the hubris and greed are evergreen.

[2] A curiosity: in 1980, a University of Washington researcher named Patricia A. Nolen wrote a poem in the style of Poe's “The Raven,” in which the bird repeats a single word in a not-quite-human voice. Nolen’s version worries about Speak & Spell but hopes it might enhance learning by removing tiresome drill from the classroom.
