  • Platform: Atari 520ST

ST Speech (short for the Atari 520ST Speech Synthesiser, filename STSPEECH.TOS) was a public domain[2] speech synthesiser application for the Atari 520ST.

As the Atari ST was an affordable home computer with built-in MIDI ports, it was used by many European musicians of the era. It's little wonder, then, that this application's distinctive voice ended up in various songs.


You can change the speed with the percent symbol and a number, between %1 and %127. A lower number is quicker, and a higher number slower. I believe %100 makes it regular speed.

You can change the pitch with the exclamation mark and a number, between !60 and !127. A lower number is higher pitched, and a higher number is lower pitched. I believe the original's somewhere around !75 or !80.

You can toggle between English text mode and phoneme mode with a full stop by itself. Whenever you type in text in English text mode, it displays the phoneme equivalent. Phoneme mode lets you type that in directly.
