Text To Speech (TTS/Speech synthesis) is the artificial production of human speech. The computer system used to achieve this is called a speech engine.
Acapela Text to Speech (TTS/Speech synthesis) transforms any text into speech in real time. It literally reads out loud any written information with a smooth and natural sounding voice. The automatic intonation reflects the meaning of the text, with respect to pauses, breath groups, punctuation and context.
The most important qualities of a speech synthesis system are naturalness and intelligibility. Naturalness describes how closely the output sounds like human speech, while intelligibility is the ease with which the output is understood. The ideal speech synthesizer is both natural and intelligible. Acapela Text To Speech maximizes both characteristics.
