The International Workshop on Spoken Dialogue Systems Technology (IWSDS) 2025 will invite paper submissions. IWSDS 2025 will be held May, 27-30, 2025 in Bilbao, Spain. This year’s conference theme is: Conversational Systems for Emotional Support and Customer Assistance. We especially invite paper submissions on the following topics:

- User engagement and emotion in dialogue systems
- Proactive, anticipatory, or incremental interaction
- Use of humor and metaphors in dialogue systems
- Multimodal and situated dialogue systems
- Companions and personal assistant dialogue systems
- Educational and healthcare applications
- Big data and large scale dialogue systems
- Digital resources for interactive dialogue management
- Domain transfer and adaptation techniques for dialogue systems
- Dialogue systems for low-resource languages
- Multilingual dialogue systems
- Dialogue system evaluation
- Machine learning for dialogue systems
- Interaction styles in dialogue systems
- LLMs in task-oriented dialogue systems
- LLMs for context tracking and management in dialogue systems
- Ensuring safety and explainability in LLM-powered dialogue systems
- Grounded, personalized and adaptive response generation in dialogue systems
- Mitigating harmful, toxic, or biased language generation in dialogue systems
- Large-scale, high-quality dialogue corpora collection, annotation, labeling and evaluation
- Integration of AI-based consciousness and awareness capabilities on computational - systems
- Ethical considerations for AI-based systems

However, submissions are not limited to these topics and we encourage you to submit papers in all areas of natural language dialogue systems.


INDUSTRIAL TRACK
The Industrial Track invites contributions showcasing the implementation of novel and robust real-world applications of spoken dialogue systems. We encourage contributions that bridge research and practice, emphasizing robust implementation strategies and lessons learned from deployment in industrial or commercial settings. Submissions should highlight practical advancements and address challenges in areas such as, but not limited to:

- Innovative applications: new use cases and industries benefiting from spoken dialogue systems
- Efficient training and deployment: approaches for rapid, scalable, and resource-efficient model development
- Scalable, fast and cost-effective implementation: strategies enabling effective operation in resource-constrained or large-scale scenarios
- Human-in-the-Loop strategies: integration of human expertise to enhance system learning and performance
- Ethical and responsible systems: addressing fairness, transparency and societal impact in real-world applications


CATEGORIES OF SUBMISSIONS:
- Long Papers: These are reserved for reports on mature original research results. Review versions of long papers may have up to eight (8) pages of content plus unlimited pages for references. Upon acceptance, final versions of long papers will be given one additional page – up to nine (9) pages of content plus unlimited pages for acknowledgments and references – so that reviewers’ comments can be taken into account. All figures and tables that are part of the main text must fit within these page limits. The conference encourages submission of appendices and supplementary material, which are not required to fit within these page limits. However, review versions of papers must be self-contained: it is optional for reviewers to look at appendices or supplementary material.
- Short Papers: Authors may choose this category if they wish to report on smaller case studies or ongoing original research efforts. Review versions of short papers may have up to four (4) pages of content, plus unlimited pages for references. Final versions of short papers may have up to five (5) pages, plus unlimited pages for acknowledgments and references. All figures and tables that are part of the main text must fit within these page limits. The conference encourages submission of appendices and supplementary material, which are not required to fit within these page limits. However, review versions of papers must be self-contained: it is optional for reviewers to look at appendices or supplementary material.
- Position Papers: These deal with novel unexplored research ideas or viewpoints which describe trends or fruitful starting points for future research and elicit discussion. The expected length of a position paper submission should be 2 pages of content, plus up to 2 pages for references. Final versions (after notification of acceptance) will be given 1 additional page of content (2-3 pages of content) so that reviewers' comments can be taken into account but the number of pages for references will not change (up to 2 pages).
- Demo/System Papers: Authors who wish to demonstrate their system may choose this category and provide a description of their system and demo. The expected length of a demo/system paper submission should be up to 5 pages of content, plus unlimited pages for references. Final versions (after notification of acceptance) will be given 1 additional page of content (up to 6 pages of content) so that reviewers' comments can be taken into account, plus unlimited pages for acknowledgments and references.
