== Background ==
The Speak & Spell was created by a small team of engineers led by Paul Breedlove, himself an engineer, with Texas Instruments (TI) during the late 1970s. Development began in 1976 with an initial budget of $25,000, as an outgrowth of TI's research into speech synthesis.〔''(Speak & Spell introduced – first commercial use of DSP technology )''. Texas Instruments. Retrieved 17 December 2008.〕 The completed proof version of the first console utilized TI's trademarked Solid State Speech technology to store full words in a solid state format similar to the manner in which calculators of the time stored numbers. Additional purchased cartridges (called expansion modules) could be inserted through the battery receptacle to provide new solid-state libraries and new games.〔 This represented the first time an educational toy utilized speech that was not recorded on tape or phonograph record (as with Mattel's See 'n Say line or the earlier Chatty Cathy dolls).〔
