This was a complex machine to operate. After months of practice, a trained operator could produce recognizable speech. [2] Voder demonstration by Bell Labs at the 1939 New York World's Fair [3] Performances on the Voder were featured at the 1939 New York World's Fair and in San Francisco. Twenty operators were trained by Helen Harper ...
The development of a vocoder was started in 1928 by Bell Labs engineer Homer Dudley, [5] who was granted patents for it on March 21, 1939, [6] and Nov 16, 1937. [7]To demonstrate the speech synthesis ability of its decoder section, the voder (voice operating demonstrator) [8] was introduced to the public at the AT&T building at the 1939–1940 New York World's Fair.

Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...
Specialized devices can recognize few words and accuracy is not very high. [1] 1971–1987: Speech recognition rapidly improves, although the technology is still not commercially available. [1] 1987–2014: Speech recognition continues to improve, becomes widely available commercially, and can be found in many products. [1]
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition (ASR), computer speech recognition or speech-to-text (STT).
Bell Labs was Alcatel-Lucent's research and development (R & D) organization. [48] In 1876, Alexander Graham Bell was awarded the first patent for the telephone, and subsequently started AT&T. [49] Bell Labs is named in his honor. [citation needed] In 1937, Clinton Davisson shared the Nobel Prize in Physics for demonstrating the wave nature of ...
SIGSALY (also known as the X System, Project X, Ciphony I, and the Green Hornet) was a secure speech system used in World War II for the highest-level Allied communications. It pioneered a number of digital communications concepts, including the first transmission of speech using pulse-code modulation.
In 1952, Bell Labs presented "Audrey", the Automatic Digit Recognition machine. It occupied a six-foot-high relay rack, consumed substantial power, had streams of cables and exhibited the myriad maintenance problems associated with complex vacuum-tube circuitry. It could recognize the fundamental units of speech, phonemes.
