Speech technologies have the potential of introducing essential changes to human interaction with their environment. If a person is able to speak to a computer, and if the computer is able to speak back, then similar communication with other devices can be realized, starting from home equipment through industrial machines, cars, robots and toys, all the way to remote computers which can retrieve the required information and deliver it by speech.

ASR and TTS represent very complex multidisciplinary problems, and their successful treatment requires not only technical skills, but also expert knowledge in areas such as linguistics, psychoacoustics and speech perception, acoustics and digital signal processing. All these elements need to be combined and implemented into available hardware and software resources in order for a computer to be enabled to understand human utterances and to generate speech of its own.
