The Speak & Spell project was started in the year 1976 and created with the TMC0280 the first one-chip LPC speech synthesizer. Later refinements to the Speak & Spell chips resulted in the TMS5100, 5200 and 5220 Voice Synthesis Processors (VSP) for use in commercial products needing synthetic speech voice output from digitally-stored words and phrases. Speech data was stored in in up to sixteen VSM (Voice Synthesis Memory) ROM chips with a capacity of 128k Bits (TMC0350), each.
Dismantling this Speak & Spell Compact manufactured in November 1982 by Texas Instruments in Abilene, Texas reveals a design centered around three Integrated Circuits:
• CD8011A: 4-bit
TMS1100 microcontroller with 2k Bytes ROM and 128*4 Bits RAM
• TMC0281: TMS5100A VSP (Voice Synthesis Processors)
• TMC0350/CD2354A: VSM (Voice Synthesis Memory) with 128k Bits
