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:
| Pin# | 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
