Thirty-eight yearsago today, Texas Instruments introduced its Speak and Spell. This learning toywhich helped children learned to spell was the first device with a human voicetract electronically encoded on a single silicon chip. Its single chip voicesynthesizer transformed the way the human voice was digitized and processed.Before the Speak and Spell, the human voice was recorded on a tape orphonograph like Mattel’s See ‘n Say or the “speaking” dolls of the time. Today,there are single silicon chip computers – one called C.H.I.P. sells for around$9.00, another called Pi Zero sells for around $5.00. The Speak and Spell wasalso an integral part of E.T.’s communicator back in 1982.
