Speech output in HCI technologies

Computer speech for human-computer interaction (HCI) is being developed for use in information access systems and in exchanging information among users. However, in order to be useful and acceptable, computer voice output systems must be of high quality and interface easily with language understanding systems and voice recognition. In most cases, the success of the entire interaction system will be judged by how easy communication is between human user and machine. Therefore, poor speech output will detract from the full applicability of the HCI system
