TI Speech Synthesizer Module

TI Speech Synthesizer Module

Release Date: 1/1/1979
 
 
In the early 1980s, TI was known as a pioneer in speech synthesis, and a highly popular plug-in speech synthesizer module was available for the TI-99/4 and 4A. Speech synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games (notable titles offered with speech during this promotion were Alpiner and Parsec). The synthesizer used a variant of linear predictive coding and had a small in-built vocabulary. The original intent was to release small cartridges that plugged directly into the synthesizer unit, which would increase the device's built in vocabulary. However, the success of software text-to-speech in the Terminal Emulator II cartridge cancelled that plan. (Most speech synthesizers were still shipped with the intriguing door that opened on the top, although very few had the connector inside. There are no known speech modules in existence for those few units with the connector.) In many games (mostly those produced by TI), the speech synthesizer had relatively realistic voices. As an example, Alpiner's speech included male and female voices and could be quite sarcastic when the player made a bad move.
