Text to Speech chip for SpeakJet - TTS256

Product Description

Description: 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:

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.
