LINGUA: An Open Call from Microsoft’s AI for Good Lab

On this European Day of Languages celebrating Europe’s rich linguistic and cultural diversity, we are excited to encourage lifelong language learning and greater intercultural understanding by releasing the LINGUA Open Call. This call invites proposals that advance digital inclusion for Europe’s low-resource languages. These are languages with limited online content and datasets, leading to underrepresentation in AI technologies compared to high-resource counterparts such as English, Spanish, French, or German. While many vulnerable and endangered languages fall into this category, the call is open to any European language that lacks the digital foundations required for fair representation and participation in the AI era.

LINGUA aims to address this gap by supporting innovative projects that collect high-quality speech and text datasets for Europe’s underrepresented languages. It is part of Microsoft’s commitment to digital sovereignty and linguistic diversity in Europe, ensuring that every language has the opportunity to be represented in the future of AI.

Our commitment

As the Microsoft AI for Good Lab, we are deepening our commitment to Europe’s digital future by supporting linguistic diversity, digital sovereignty, and inclusive innovation. The LINGUA Open Call is part of the EU Digital Unlock initiative, which aims to make Europe’s languages and cultures more open and accessible in the digital era. We are proud to collaborate with nonprofits, universities, research institutes, startups, and cultural organizations to enhance resources for low-resource languages, close digital gaps, and maximize impact through shared knowledge and collective action.

We are excited to launch this initiative in close coordination with the APERTUS project led by EPFL & ETH Zurich, and in consultation with the Council of Europe. Together, we are building data resources for 10 European languages, expanding the supply of multilingual datasets, and enhancing the performance of low resource language LLMs. Our goal is to ensure that Europe’s rich linguistic and cultural heritage is fully represented in the next generation of AI models (e.g., Apertus (opens in new tab), EuroLLM, SmolLM3) by empowering communities, fostering innovation, and recognizing the people and organizations that make Europe a hub of creativity and inclusion.
