speech synthesisGeneration of speech by artificial means, usually by computer. Production of sound to simulate human speech is referred to as low-level synthesis. High-level synthesis deals with the conversion of written text or symbols into an abstract representation of the desired acoustic signal, suitable for driving a low-level synthesis system. Among other applications, this technology provides speaking aid to the speech-impaired and reading aid to the sight-impaired. speech synthesisGenerating machine voice by arranging phonemes (k, ch, sh, etc.) into words. It is used to turn text input into spoken words for the blind. Speech synthesis performs real-time conversion without a predefined vocabulary, but does not create perfect-sounding human speech. Although individual spoken words can be digitized into the computer, it takes more storage, and the resulting phrases still lack inflection. Spoken phrases that are repetitively used in voice applications are usually digitized whole to provide the most pleasing announcements.
