Many systems based on formant synthesis technology generate artificial, robotic-sounding speech that would never be mistaken for human speech. However, maximum naturalness is not always the goal of a speech synthesis system, and formant synthesis systems have advantages over concatenative systems. Formant-synthesized speech can be reliably intelligible, even at very high speeds, avoiding the acoustic glitches that commonly plague concatenative systems. High-speed synthesized speech is used by the visually impaired to quickly navigate computers using a screen reader]]. Formant synthesizers are usually smaller programs than concatenative systems because they do not have a database of speech samples. They can therefore be used in embedded systems, where data storage devicememory and microprocessor power are especially limited. Because formant-based systems have complete control of all aspects of the output speech, a wide variety of prosodies and intonation (linguisticsintonations can be output, conveying not just questions and statements, but a variety of emotions and tones of voice.

Festival Speech Synthesis System is one such tool. Festival grew out of the need for a unifying, flexible, and extensible tool for research and educational purposes at The Centre for Speech Technology Research (CSTR) at University of Edinburgh.
Speech synthesis is the artificial production of human speech
Festival is a free, portable, extensible, language-independent, run-time speech synthesis engine for various platforms that has been under development since 1999. Primary authors of the C++ system include Alan W Black, Paul Taylor, and Richard Caley. Festival is a part of the project that aims to make the building of new synthetic voices more systematic and better documented, making it possible for anyone to build a new voice.
