Gaelic and Breton, the same fight against AI.

A language can survive among people and disappear from machines. In the face of the rise of artificial intelligence, Irish and Breton must now have vast digital resources to avoid being marginalized by new technologies like AI.

Artificial intelligence represents a tremendous opportunity for minority languages, but it could also accelerate their disappearance from the digital world. This is the warning issued by Tomás Ó Síocháin, the director general of Údarás na Gaeltachta, the Irish public agency responsible for the development of Gaelic-speaking regions, during the Interceltic Business Forum in Lorient. The question is no longer just about saving a language by increasing the number of its speakers: it is now necessary to provide it with enough digital data for it to exist in machines. Large AI models are trained on vast corpora of texts, documents, and recordings in which English and major languages are overrepresented. Languages with few digital resources are therefore at risk of being left behind.

Who owns the corpora?

Ireland has already built significant reserves of digital data in Irish. But Ó Síocháin raises a second question: should these corpora be entrusted to American giants of artificial intelligence? He cites two different strategies. Iceland has provided data to OpenAI to improve the performance of its models in Icelandic, while the Māori of New Zealand have prioritized sovereignty over their data and the development of their own tools. Údarás is currently pursuing both paths: working with major platforms while supporting local and European solutions. It assesses the performance of the main AI models in Irish every month and is experimenting with HubChat, an assistant intended for public services.

For Ó Síocháin, it is not enough for an artificial intelligence to produce approximately correct Irish. During the questions, he emphasizes that a solution that is simply "good enough" is not sufficient for a minority language: the models must also convey the context, nuances, and culture specific to the language, instead of mechanically transposing a worldview learned from a dominant language. He hopes that the European Union will take more responsibility for this issue and announces a conference on linguistic diversity during the next Irish presidency of the Union.

Breton facing the same challenge

Speaking at the end of the presentation, Breton MP Paul Molac immediately drew a parallel with Breton. Spell checkers, GPS, voice recognition, or machine translation: the possibility of using a language daily now depends on its presence in these new tools. He recalls the work carried out by the Public Office of the Breton Language, particularly on voice recognition, which should ultimately allow for direct translation of a person speaking Breton into French or English. "It is absolutely necessary if we want our languages to endure [...] for the century to come," says the MP, who likens biodiversity to "glottodiversity," the diversity of languages that is also threatened today.

Building the corpora requires resources

The problem has been known for several years in Brittany. Linguist Mélanie Jouitteau, a researcher at CNRS, is working on the creation and availability of digital resources in Breton. However, the project for a sustainable corpus platform presented by Mélanie Jouitteau and Reun Bideault to the DGLFLF was not selected for funding.

Digitizing books and archives, collecting and transcribing thousands of hours of speech, organizing and making this data accessible represents a considerable amount of work. Other governments have recognized the stakes: the Spanish state and the Basque government have invested 10.5 million euros in a program aimed at developing the digital linguistic resources of Euskara. If we want Breton to exist in the artificial intelligence of tomorrow, the creation of its corpora can no longer rely solely on researchers and associative initiatives: it must become a public policy in its own right. This is also what Yann Le Cun suggested for Breton.
