With its debut announced at the Consumer Electronics Show in 1978, Texas Instruments' Speak & Spell consisted of a speech synthesizer, a keyboard, an LCD screen and an expansion port for game cartridges, including Hangman. It was the first educational toy that did not use prerecorded speech and it helped countless youths learn to spell and pronounce words. From 1978 to 1992, the Speak & Spell was available in seven different languages.
