Vocoder (English Wikipedia)

"The 'Voder' & 'Vocoder' Homer Dudley, USA, 1940". 120 Years of Electronic Music (120years.net). 2013-09-21. The Vocoder (Voice Operated reCorDER) and Voder (Voice Operation DEmonstratoR) developed by the research physicist Homer Dudley, ... The Voder was first unveiled in 1939 at the New York World Fair (where it was demonstrated at hourly intervals) and later in 1940 in San Francisco. There were twenty trained operators known as the 'girls' who handled the machine much like a musical instrument such as a piano or an organ, ... This was done by manipulating fourteen keys with the fingers, a bar with the left wrist and a foot pedal with the right foot.
