KEMPELEN, Johann Wolfgang Ritter von
Mechanismus der menschlichen Sprache nebst Beschreibung seiner sprechenden Maschine.Vienna: J. B. Degen, 1791.
Kempelen built the first successful speech synthesizer that produced not only some speech sounds, but also whole words and short sentences. His final version of the machine, which differs slightly from the version shown in the book, is preserved in the Deutsches Museum Munich, in the department of musical instruments.
