The TTS256 is an 8-bit microprocessor programmed with letter-to-sound rules. This built-in algorithm allows for the automatic real-time translation of English ASCII characters into allophone addresses compatible with the Magnevation SpeakJet Speech Synthesizer IC. Combine this with the SpeakJet to build a complete text-to-speech solution.
The TTS256 is offered in a through-hole, 28-pin package. Supplied power should be +5V. Very few connections are required for operation:
|5||TX (sends serial data to host)|
|18||RX (received serial data from host)||15||Buffer Half Full|
The TTS256 contains over 600 rules for pronouncing English text. While it does a pretty good job of the task, with a less than 5% error rate in most sentences, it will mispronounce some words. Often times, some creative spelling will help.
