Requirement Engineering Contributions to Voice User Interface

This paper aims to contribute to the voice user interface systems area by establishing directions to be used during the requirements engineering phase of the development of this type of system. The process of requirements engineering proposed here takes into account specific characteristics of voice user interface, and is based on concepts deriving from the software engineering area, namely the elicitation, specification, and evaluation phases. In order to illustrate the process, a case study is discussed and presented, as well as the conclusions obtained during the development of the research.
