Abstract
With the technical advances and market growth in the field, the issues of evaluation and usability of spoken language dialogue systems, unimodal as well as multimodal, are as crucial as ever. This paper discusses those issues by reviewing a series of European and US projects which have produced major results on evaluation and usability. Whereas significant progress has been made on unimodal spoken language dialogue systems evaluation and usability, the emergence of, among others, multimodal, mobile, and domain-oriented systems continues to pose entirely new challenges to research in evaluation and usability.
