Product 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.
iPn# TTS256 -> Pin# SpeakJet
5 TX (sends serial data to host) 14 Vss (ground) 18 RX (received serial data from host) -> 15 Buffer Half Full
20 Ready ->10 RX
24 SJ_TX 28 Vdd (+5V)
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.
Features:
Narrow 28-pin DIP
Companion chip to Magnevation SpeakJet and Savage Innovations SpeakGin
Built in 600 Rule database
9600bps (8-N-1) serial interface (non-inverted TTL level)
Generates speech codes from ASCII text
Compatible with Arduino, Basic Stamp, OOPic, Pic, and any processor with serial output
Datasheet Errata: The correct character to append to the end of text is 0x0D and not 0x0A as listed
