Аннотация:ABSTRACT: This is a summary of the state‐of‐the‐art research in international intelligibility with emphasis on English. It also suggests some directions for future research. It is argued that in future research it would be desirable to make distinctions between three key concepts: intelligibility, comprehensibility and interpretability . The selected bibliography of 163 items has been assembled to give the reader an indication of how widespread this literature is, and at the same time to indicate its limitations. The sources searched include publications across various disciplines. This indicates that intelligibility can be approached from a variety of points of view and interests. Since intelligibility depends upon so many factors of different types involved in a given speech event, it is difficult to find ways of integrating approaches and parameters. That is a challenge for future research.
