Vintage General Instrument Speech Synthesizer CTS256 with SP0256
This single-board computer helps hobbyists and retro computing enthusiasts experiment with and test vintage speech synthesis technology. You input phonetic codes (allophones), and the board pronounces them as words using the General Instrument CTS256A and SP0256 chips. It's designed for someone creating or debugging custom speech dictionaries for these classic synthesizers.

Use this if you are a retro computing enthusiast or hobbyist working with vintage General Instrument speech chips and need a physical board to test allophone combinations for custom word pronunciations.
Not ideal if you are looking for modern text-to-speech solutions or do not have experience with vintage hardware and allophone-based speech programming.
