Speak & Read is an electronic learning aid made in 1980, by Texas Instruments. Speak and Read was part of a family of learning toys i.e. "Speak & Math" and "Speak & Spell".
Speak & Read helped children from ages four to eight develop and improve their reading comprehension and vocabulary. The toy has a vocabulary of 250 words.
The display is a vacuum fluorescent display (VFD). Speak & Read units used a membrane keyboard for input. The Speak & Read used a single-chip voice synthesizer, the TI TMC0280 (later called the TMS5100), that was also used in the Speak & Spell. The TMS5100 used a 10th-order linear predictive coding (LPC) model and the electronic DSP logic.
LPC encoded speech data was stored on a pair of TMS6100 128 Kbit metal gate serial PMOS ROMs. 128 Kbit was a very large capacity ROM in the early 1980s. Additional memory modules could be plugged into a slot in the battery compartment and selected via a button on the keyboard. A later model, the Super Speak & Read, had a much slimmer case and an LCD screen rather than a VFD screen.
The unit could use either 4 "C" batteries or 6 volt DC power adapter with positive tip polarity.
Speak & Read has six built-in learning games: Word Zapper, Word Maker, Read It, Picture Read, Letter Stumper, and Hear It. Picture Read required looking up pictures in the supplementary booklet that came with the unit. Eight expansion modules were known to have been made for the Speak & Read by 1986.
