TMS5220 - Bare.jpg
Developer: Texas Instruments
Released: 1980-??-??
Type: Chip

The TMS5220 is a collection of audio chips designed and sold by Texas Instruments specifically designed to mimic human speech. Speech data is stored through pitch-excited linear predictive coding (PE-LPC), where words are created by a lattice filter, selectably fed by either an excitation ROM (containing a glottal pulse waveform) or an LFSR (linear feedback shift register) noise generator. Linear predictive coding achieves a vast reduction in data volume needed to recreate intelligible speech data.

The TMS5220 had the same pinout as the earlier TMS5200, but it used a new LPC tables breaking backward compatibility.

The TMS5220, released in 1980, was used in several home computer peripherals and arcade games. Uses the 'final' chirp table. HP 82967A Speech synthesis module, adding 1500-word vocabulary to Series 80 computers. It was made until around 1983 when it was replaced by the TMS5220C.

The TMS5220C, released in 1983, was an improved TMS5220. It reworked the two NOP (No Operation) commands and the parallel FIFO interface to allow for variable-speed speech and was fully compatible with the TMS5220. Those chips produced after 1985 used the number "TSP5220C". It was made until the early 1990s.
