Advances in speech technologies for motor speech disorders (MSD) have enabled new approaches to clinical assessment, monitoring, and assistive communication. However, these developments have largely focused on high-resource languages, limiting their applicability across diverse linguistic and clinical populations. Although interest in multilingual and cross-lingual approaches is increasing, coordinated efforts that integrate datasets, methodologies, and expertise across languages remain limited.

OneVoice-MSD 2026 aims to address this gap. The session brings together researchers working on multilingual and cross-lingual approaches to MSD, with the goal of fostering collaboration and facilitating the exchange of data, methodologies, and findings. We welcome submissions that contribute to a better understanding and modeling of MSD across languages and populations.

To foster MSD research across languages, this session offers ethically approved, research-only datasets in Spanish, German, and Czech for participants to use in their submissions. The session features two submission tracks: a Focused Track, for studies utilizing these shared datasets, and an Exploratory Track, for research employing other public or private corpora relevant to motor speech disorders. Authors of Focused Track papers may be invited to join a panel discussion, where they can present methodological advances and key findings in cross-language modeling.

Topics of interest include, but are not limited to: 

• Multilingual/Cross-lingual analysis of acoustic, articulatory, and linguistic markers of MSD

• Dataset harmonization across languages and clinical cohorts

• Automatic speech recognition or acoustic modeling

• Severity estimation and progression monitoring

• Multimodal integration of speech, language, and clinical metadata

The Special Session follows the same guidelines as the SLT 2026 main conference.
