This collaborative workshop focuses on theories and methods we can use to understand user behaviours with speech interfaces.</div><div class=""><br class=""></div><div class="">Through the workshop we will establish what theories, concepts, and paradigms are important in understanding our interaction choices with speech interfaces, and potential new theoretical frame- works required to explore them. We will critically evaluate existing methodologies used to explore these interactions and determine priority areas for improving methods to explore the theories and paradigms identified.</div><div class=""><br class=""></div><div class="">This workshop brings together researchers and practitioners from any domain interested in understanding user interaction behaviours with speech interfaces. Interested researchers are invited to submit position papers outlining a theory, concept or paradigm and related research methods and highlight their importance in understanding user behaviour in speech interface interactions.</div><div class=""><br class=""></div><div class="">Position papers should be 2 pages maximum (excluding references) in the CHI EA format and submitted by February 22nd. Papers will be reviewed by the organisers and chosen based on 1) relevance to the workshop; 2) quality of the contribution; 3) ability to contribute to discussion. Once accepted, at least one author must register for the workshop and at least one day of the CHI 2019 conference.
