However, more recent mechanical larynxes have demonstrated similar voice production to commercially available electrolarynxes. [4] Electrolarynxes were introduced in the 1940s, at a time when esophageal speech was being promoted as the best course in speech recovery; however, since that technique is difficult to master, the electrolarynx became ...
Its key features included a sight scope with cross-hairs, two flashing battery-powered red eyes with an on-off switch, a hand-cranked mechanical voice box that played ten messages, two rubber-tipped darts that were fired from triggers on the back, a left arm that held four red balls which were fired from a spring in the left elbow, and a right ...

The larynx (/ ˈ l æ r ɪ ŋ k s /), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter . [ 1 ]
A voice prosthesis (plural prostheses) is an artificial device, usually made of silicone that is used in conjunction with voice therapy to help laryngectomized patients to speak. During a total laryngectomy, the entire voice box is removed and the windpipe and food pipe are separated from each other. During this operation an opening between the ...
Frances Densmore and Blackfoot chief Mountain Chief working on a recording project of the Bureau of American Ethnology (1916).. Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects.
The very earliest mechanical telephones were based on transmission through pipes or other physical media, and among the very earliest experiments were those conducted by the British physicist and polymath Robert Hooke from 1664 to 1685. [1] [2] From 1664 to 1665 Hooke experimented with sound transmission through a taut extended wire. [3]
