Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech ( TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic ...
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.

DECtalk[ 4] was a speech synthesizer and text-to-speech technology developed by Digital Equipment Corporation in 1983, [ 1] based largely on the work of Dennis Klatt at MIT, whose source-filter algorithm was variously known as KlattTalk or MITalk. [ 5][ 6] Uses ranged from interacting with the public to allowing those with speech disabilities ...
Vocaloid (ボーカロイド, Bōkaroido) is a singing voice synthesizer software product. Its signal processing part was developed through a joint research project between Yamaha Corporation and the Music Technology Group in Universitat Pompeu Fabra, Barcelona. [ 1]
Speech recognition is at an early stage of development. 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 ...
Speech synthesis. Robotic voices in music may also be produced by speech synthesis. This does not usually create a "singing" effect (although it can). Speech synthesis means that, unlike in vocoding, no human speech is employed as basis. One example of such use is the song Das Boot by U96. A more tongue-in-cheek musical use of speech synthesis ...

Currah. Currah was a British computer peripheral manufacturer, famous mainly for the speech synthesis ROM cartridges it designed for the ZX Spectrum, Commodore 64, and other 8-bit home computers of the 1980s.
