25 Facts About Speech synthesis

The first video game to feature speech synthesis was the 1980 shoot 'em up arcade game, Stratovox, from Sun Electronics.

The first personal computer game with speech synthesis was Manbiki Shoujo, released in 1980 for the PET 2001, for which the game's developer, Hiroshi Suzuki, developed a "zero cross" programming technique to produce a synthesized speech waveform.

The quality of synthesized speech has steadily improved, but as of 2016 output from contemporary speech synthesis systems remains clearly distinguishable from actual human speech.

Concatenative synthesis is based on the concatenation of segments of recorded speech.

Diphone synthesis uses a minimal speech database containing all the diphones occurring in a language.

An early example of Diphone synthesis is a teaching robot, Leachim, that was invented by Michael J Freeman.

Domain-specific Speech synthesis concatenates prerecorded words and phrases to create complete utterances.

Many systems based on formant synthesis technology generate artificial, robotic-sounding speech that would never be mistaken for human speech.

Articulatory synthesis refers to computational techniques for synthesizing speech based on models of the human vocal tract and the articulation processes occurring there.

Until recently, articulatory synthesis models have not been incorporated into commercial speech synthesis systems.

HMM-based Speech synthesis is a Speech synthesis method based on hidden Markov models, called Statistical Parametric Synthesis.

Speech synthesis waveforms are generated from HMMs themselves based on the maximum likelihood criterion.

Sinewave synthesis is a technique for synthesizing speech by replacing the formants with pure tone whistles.

Deep learning speech synthesis uses deep neural networks to produceartificial speech from text or spectrum.

The quality of speech synthesis systems depends on the quality of the production technique and on the facilities used to replay the speech.

So, the demo was accomplished with a prototype 512k Mac, although those in attendance were not told of this and the Speech synthesis demo created considerable excitement for the Macintosh.

The voice synthesis was licensed by Commodore International from SoftVoice, Inc, who developed the original MacinTalk text-to-speech system.

The synthesis system was divided into a translator library which converted unrestricted English text into a standard set of phonetic codes and a narrator device which implemented a formant model of speech generation.

Speech synthesis was occasionally used in third-party programs, particularly word processors and educational software.

The synthesis software remained largely unchanged from the first AmigaOS release and Commodore eventually removed speech synthesis support from AmigaOS 2.

Microsoft Speech Server is a server-based package for voice synthesis and recognition.

Speech synthesis synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games.

Speech synthesis has long been a vital assistive technology tool and its application in this area is significant and widespread.

Speech synthesis techniques are used in entertainment productions such as games and animations.

Text-to-speech is finding new applications; for example, speech synthesis combined with speech recognition allows for interaction with mobile devices via natural language processing interfaces.
