Dialogue design principles - key for usability of voice processing

Christel Müller, Fred Runge

Communication systems with voice processing are becoming more and more important for all users of new services (audiotex, voice mail and fax, automated responses, ordering systems...). Usability of these new features and services depend essentially on the dialogue every user has to handle. It is common, that the success rate of voice controlled services in modern system applications with a determined dialogue handling is considered from the users point of view, i.e. from the person who takes part in these interactions. Speech interfaces represent a subset of user interfaces for multimodal dialogues and are of main interest for services in telecommunication applications. This paper analyses the different methods of dialogue design - from high level specification languages to graphical dialogue description tools. The evaluation of these dialogue design tools includes the formal and imperial criteria and the generic usability principles. The main research goal for dialogue design (to involve human factors into the design process) is considered.
