  • Narrow 28-pin DIP
  • Companion chip to Magnevation SpeakJet or the Savage Innovations SpeakGin
  • Built in 600 Rule database convert English text to phoneme codes
  • 9600 N81 Baud Serial interface (TTL level)
  • Generate speech from ASCII text
  • Compatible with Basic Stamp, OOPic, Pic and any processor with a serial port

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.

 Pin # TTS256  Pin #  SpeakJet
 5  TX (sends serial data to host)    
 14  Vss (ground)    
 18  RX (received serial data from host)    
 20  Ready  15  Buffer Half Full
 24  SJ_TX  10  RX
 28  Vdd (+5v)    

The TTS256 contains over 600 rules for pronouncing English text. While I think it does a pretty good job of the task with a less than 5% error rate in most sentances, I guarantee that it will mispronouce some words.   Often times, some creative spelling will help.
