MediaLab presents the research and activities of the Department of Speech, Media and Content Technologies at the Institute for Language and Speech Processing (ILSP), Athena Research Center. Our work spans speech and language technologies, music and audio, intelligent multimedia, and digital cultural heritage, with applications in education, accessibility, health and the creative industries.
Speech, Language, Music and AI
- Speech signal analysis, recognition and synthesis; expressive and spontaneous speech
- Spoken interaction and multimodal communication
- Language modelling, multilingual content and domain-specific NLP
- Audio and music analysis, recommendation and interactive learning
- Machine learning for speech, audio, language and visual content
Department members Georgios Paraskevopoulos, Athanasios Katsamanis and Vassilis Katsouros contributed to Krikri: Advancing Open Large Language Models for Greek (Findings of EMNLP 2025), together with colleagues across ILSP. This collaboration advances open language models for Greek.
Through ILSP’s participation in PHAROS – The Greek AI Factory (April 2025–March 2028), with Vassilis Katsouros as the ILSP project leader, the department contributes to a national partnership supporting AI research and innovation, including culture and language. PHAROS brings together multiple institutions and partners.
