Important early work on speech synthesis on loan to OHSU

OHSU Historical Collections & Archives is pleased to announce that a first edition of Wolfgang von Kempelen's monumental work on speech synthesis, Wolfgangs von Kempelen Mechanismus der menschlichen Sprache nebst Beschreibung seiner sprechenden Maschine (or, Wolfgang von Kempelen's Mechanism of Human Speech with a Description of his Speaking Machine) is now available to researchers for consultation. This pioneering study of artificial speech and phonetics has been placed on long-term loan by Richard Sproat, PhD, Professor, Department of Science & Engineering. 

The book includes detailed diagrams of the machine constructed by Kempelen and of the human vocal apparatus. A working copy of Kempelen's voice synthesizer has been reproduced using the text, and is on display at the Deutsches Museum in Munich. The first edition of Kempelen's work is extremely scarce, as are later reprints, and the text is not available digitally. Dr. Sproat and the OHSU Library will investigate the possibility of digitizing this item while it is on loan. Of note: This particular copy is from the collection of Andras Gedeon, author of Science and technology in medicine: an illustrated account based on ninety-nine landmark publications from five centuries (2006).
