Voice user interfaces (VUIs) emerge

摘要

Human beings use speech as the primary means of communication. Therefore, voice user interfaces (VUIs) represent a natural way for people to interact with computers (Fournier, 1996; Hyde, 1979; Teja and Gonnella, 1983; Witten 1982). Voice input facilitates a much higher computer input rate than keyboard or mouse driven input. Voice output permits computer generated output in devices when output screens are not available (e.g., most phones) or in situations where the useru27s eyes are busy elsewhere (e.g., driving a car, assembling a product, etc.). Thus, VUIs are viewed as the logical next generation in computer interfaces. Forecasts call for a rapid expansion of voice technology within our work environments over the next few years (Cone, 1997; Schwartz and Brier, 1997). This paper discusses the current state of and potential future of VUIs.
