Recorded in 1964 by Harm A. Drost, this album demonstrates the evolving developments in artificial voice creation after the removal of the larynx. After a growing interest in artificial voice production, Drost deemed that "A phonograph record demonstrating some of these forms of speech in which sounds are created without the use of vocal cords therefore seemed to US a useful contribution." the album walks the listener through the different available methods. Liner notes include detailed information on each method demonstrated in the tracks.
