Editing Speech synthesis (section)

===Mattel===
The [[Mattel]] [[Intellivision]] game console offered the [[Intellivoice]] Voice Synthesis module in 1982. It included the [[General Instrument SP0256|SP0256 Narrator]] speech synthesizer chip on a removable cartridge. The Narrator had 2kB of Read-Only Memory (ROM), and this was utilized to store a database of generic words that could be combined to make phrases in Intellivision games. Since the Orator chip could also accept speech data from external memory, any additional words or phrases needed could be stored inside the cartridge itself. The data consisted of strings of analog-filter coefficients to modify the behavior of the chip's synthetic vocal-tract model, rather than simple digitized samples.
