Text-To-Speech Web Demo

TTS is used in a wide variety of services and applications. Commercially, help desks and voice response systems are probably the most important. On nights and weekends, when people are scarce, customers can still get some basic information from computers, for example, an account balance. The computer listens either to speech or touch tones and responds with TTS. These apps are typically over the telephone but might also be at kiosks or automated tellers.
