Von Kempelen talking machine

PHONETICS: In 1791 Wolfgang von Kempelen built a machine that could produce speech utterances. Voiced sounds as well as unvoiced consonants could be generated. Bellows were used to expel air and this air was passed through a vibrating reed.
Unvoiced sounds were produced with the reed off, and by a turbulent flow through a suitable passage. Von Kempelen claimed that, apart from the vowel sounds, approximately 19 consonant sounds could be made.
