What Laboratoire d'Informatique de l'Université du Mans, LIUM does

LIUM (Laboratoire d'Informatique de l'Université du Mans, EA 4023) is a public computer science research laboratory hosted at Le Mans Université in Le Mans, France, with a secondary site at IUT de Laval. The lab operates two teams: LST (Language and Speech Technologies), focused on automatic speech recognition, speaker diarization and verification, neural machine translation, speech-to-speech translation, language modeling, and low-resource language processing; and IEIAH (Ingénierie des Environnements Informatiques pour l'Apprentissage Humain), focused on educational technology, serious games, learning analytics, mixed reality authoring, and AI-powered tools for teachers.

The lab's product surface is built around open source software and Open Educational Resources. Flagship outputs include the MIXAP authoring tool, which lets teachers without programming skills build mixed reality (AR/VR/MR) educational activities and is being deployed across four European countries through the MIXAP-EU ERASMUS+ project; the éri+ national platform, which evaluates, trains, and certifies French academic writing across 15+ French universities under the PIA Nouveaux Cursus à l'Université program; the LIUM Speaker Diarization system, SIDEKIT, NMTpy/NMTpyTORCH, CSLM, and contributions to SpeechBrain for speech processing; and PLUME and VR-PEAS for VR learning analytics. The lab also develops educational games (TurtleTablet, Le Chaudron Magique, Smart-Fractions) and the Human Active Correction Platform for speaker diarization annotation.

LIUM does not sell products commercially. Its operating budget is sourced from French and European public research grants (ANR, ERASMUS+, PIA, Région Pays de la Loire, Le Mans Métropole), university allocations, and CIFRE industrial co-funding agreements (notably with Orange and INOD Solutions). Research is disseminated through open source software releases, HAL academic publications, and presentations at conferences such as Interspeech, ICASSP, LREC, and EIAH. The lab has produced 27+ open source tools and corpora, 62+ documented theses and HDRs, and an archive of 60+ research projects, and serves audiences spanning higher education institutions, primary and secondary schools, the global speech/NLP research community, and industrial partners in telecom and mixed reality.

• CLLE (Cognition, Langues, Langage, Ergonomie): Toulouse-based CNRS research unit on language science, linguistics, and cognition. Comparable in focus on language technologies and educational research, though stronger on psycholinguistics than engineering.
• EURECOM: French engineering school and research center in Sophia Antipolis focused on digital sciences including speech, NLP, and multimedia. Comparable small-team, grant-funded structure with strong industry links.
• EPFL EDLAB (Educational Development and Technology): EPFL unit focused on educational technology, learning analytics, and digital pedagogy. Closest peer for LIUM's IEIAH team given shared emphasis on learning environments and authoring tools.
• LORIA (Laboratoire Lorrain de Recherche en Informatique et ses Applications): French CNRS/Inria/Université de Lorraine computer science research lab with overlapping teams in NLP, speech, and learning analytics. Closest structural peer to LIUM as a multi-team French public research unit producing open-source tools.
• Idiap Research Institute: Swiss nonprofit research institute affiliated with EPFL, with strong groups in speech processing, NLP, and AI. Highly comparable mix of academic research, open-source toolkits, and industry collaborations.
• LISN (Laboratoire Interdisciplinaire des Sciences du Numérique, ex-LIMSI): CNRS/Université Paris-Saclay lab historically focused on speech processing, NLP, and human-machine interaction. Most direct peer for LIUM's LST team given overlapping speech and language research themes.

Broad incumbents

• INRIA (Institut National de Recherche en Sciences et Technologies du Numérique): French national computer science research institute that funds and hosts multiple project-teams overlapping with LIUM's themes (NLP, speech, AI for education). A larger, broader incumbent of which LIUM is effectively a regional counterpart.

Emerging players
