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 ...
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]
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.

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).
Homer W. Dudley (14 November 1896– 18 September 1980) was an American pioneering electronic and acoustic engineer who created the first electronic voice synthesizer for Bell Labs in the 1930s and led the development of a method of sending secure voice transmissions during World War Two.

The Bell Labs Holmdel Complex, in Holmdel Township, Monmouth County, New Jersey, United States, functioned for 44 years as a research and development facility, initially for the Bell System and later Bell Labs. [3] The centerpiece of the campus is an Eero Saarinen–designed structure that served as the home to over 6,000 engineers and ...
Direct voice input (DVI), sometimes called voice input control (VIC), is a style of human–machine interaction "HMI" in which the user makes voice commands to issue instructions to the machine through speech recognition.
