  Conversational user interfaces (CUIs) have become an everyday technology for
people the world over, as well as a booming area of research. Advances in voice
synthesis and the emergence of chatbots powered by large language models
(LLMs), notably ChatGPT, have pushed CUIs to the forefront of human-computer
interaction (HCI) research and practice. Now that these technologies enable an
elemental level of usability and user experience (UX), we must turn our
attention to higher-order human factors: trust and reliance. In this workshop,
we aim to bring together a multidisciplinary group of researchers and
practitioners invested in the next phase of CUI design. Through keynotes,
presentations, and breakout sessions, we will share our knowledge, identify
cutting-edge resources, and fortify an international network of CUI scholars.
In particular, we will engage with the complexity of trust and reliance as
attitudes and behaviours that emerge when people interact with conversational
agents.
