Illustration of The Euphonia, or speaking machine, exhibited by Professor Joseph Faber in London, England, in 1846. Faber's device had an artificial tongue and pharyngeal cavity controlled by keyboard (center left), and bellows controlled by a foot pedal (at lower left). The machine produced whispered speech and sang 'God Save the Queen'. There was speculation that the Euphonia did not produce its own sounds and that the device was a hoax.
