Description:

TI’s Speak & Spell
Texas Instruments Inc. introduces Speak & Spell, a talking learning aid for children aged 7 and up. Its debut marked the first electronic duplication of the human vocal tract on a single integrated circuit. Speak & Spell used linear predictive coding to formulate a mathematical model of the human vocal tract and predict a speech sample based on previous input. It transformed digital information processed through a filter into synthetic speech and could store more than 100 seconds of linguistic sounds.
