ACM Conversational User Interfaces – CUI (pronounced “coo-ee”) was founded in 2018 to bring together researchers and practitioners from a wide range of disciplines examining the design of speech and language technologies. In late 2022, CUI joined SIGCHI, the Association for Computing Machinery Special Interest Group on Computer-Human Interaction. 

The CUI 2026 conference theme is “Conversational AI: Agency and Identities!”. The conference seeks contributions from a broad range of disciplines, including human-computer interaction, computer science, engineering, speech technology, linguistics, psychology, cognitive sciences, sociology, and other cognate disciplines that advance fundamental and applied research in conversational user interfaces. We also encourage the submission of high-quality replication studies in addition to well-designed studies with null results.

Topics relevant to the conference include, but are not limited to:

        Voice user experience
        Speech Interfaces
        Text-based conversational interfaces
        Chatbots
        Speech synthesis
        Speech recognition
        Context-aware dialogue management
        Conversational search
        Methods for conversational user interface development and evaluation
        Multimodal interaction involving speech, text or other language based interfaces
        Natural language processing and understanding related to the above
        Ethical and privacy considerations related to the above
        Large Language Models (LLMs)

Papers must describe original work that has not been previously published, not accepted for publication elsewhere, and is not simultaneously submitted or currently under review in another journal or conference (including the other tracks of ACM CUI 2026).

Each submission will require the author(s) to volunteer to complete three reviews of other papers.
