This research aims at providing designers of speech recognition telephone applications with a user interface evaluation and design-aid method, as well as design guidelines. To achieve this, we first elaborated an evaluation methodology suitable for any telephone-based system using speech recognition. This method was then used to evaluate a speech-activated voice information system. This evaluation allowed us to validate the method, and improve the application's design. An automated telephone-receptionist application was then developed to integrate the lessons learned previously, and to elaborate new recognition and dialogue strategies. From these two studies, many results have been generalized in terms of recommendations and guidelines for designers of speech-activated user interfaces. Keywords: user interface design; evaluation methodology; speech recognition; telephone application; design guidelines.
