Trinity College Researchers Launch Free Irish Language Communication App for Non-Verbal Children
Researchers at Trinity College Dublin have released Geabaire, a free symbol-to-speech communication tool built specifically for the Irish language, giving non-verbal children in Irish-medium schools a voice in their own language for the first time and establishing a model that linguists say could be replicated for minority languages worldwide.
Background
For decades, non-verbal children in Ireland who attend Gaelscoileanna or Irish-medium schools have faced a fundamental contradiction: they are educated in Irish, but the assistive technology available to them — the apps and devices that allow non-verbal individuals to communicate — has been designed almost exclusively for English. Existing speech-generating tools could not be simply translated into Irish because the two languages differ fundamentally in syntax, grammar, and word order. Irish is a verb-subject-object language, meaning that sentences are structured in a way that is entirely incompatible with the underlying architecture of English-language communication apps.
The gap was identified by Julia Cummins, the mother of two minimally speaking autistic children who attend an Irish-medium school in Dublin. Cummins approached researchers at Trinity College Dublin's ADAPT Centre with a straightforward request: build something that works in Irish. What followed was a multi-year development process that required not just translation but a fundamental rethinking of how symbol-to-speech technology is constructed.
The result is Geabaire — the Irish word for chatterbox — a tool that was built from the ground up to accommodate the specific nuances of the Irish language, including its three main dialects (Connacht, Munster, and Ulster Irish) and the grammatical mutations that make Irish one of the most structurally distinctive languages in Europe. The app is being made available for free, a decision that researchers described as essential given that families of children with complex communication needs already face significant financial pressures.
Key Developments
Geabaire is now available at abair.ie, with versions for Apple and Android app stores scheduled for release before the end of September 2026. The tool allows users to select symbols that are then converted into spoken Irish, with the app handling the grammatical mutations and word order adjustments that would otherwise make direct symbol-to-speech translation impossible.
Assistant Professor Neasa Ní Chiaráin, who led the research team, described the project as a global model for minority language assistive technology. "What we have built here is not just an Irish language tool," she said. "It is a demonstration that minority languages can be supported by assistive technology without compromising their linguistic integrity. We hope this will inspire similar projects for Welsh, Basque, Catalan, and other languages that have been underserved by the assistive technology sector."
The app has already been piloted in Gaelscoil Eoin in Dublin, where teachers reported that it transformed the social experience of non-verbal pupils. "The other children are fascinated by it," one teacher said. "They use it to talk to their classmate, and suddenly there is a conversation happening that wasn't possible before." Cummins, whose children were among the first to use the tool, described the experience of hearing her son communicate in Irish for the first time as "overwhelming."
Why It Matters
The launch of Geabaire addresses a gap that has existed since the expansion of Irish-medium education in the Republic of Ireland over the past three decades. There are now more than 270 Gaelscoileanna across the Republic, educating approximately 60,000 children, and a further network of Irish-medium schools in Northern Ireland. Within those schools, children with complex communication needs have been systematically disadvantaged by the absence of Irish-language assistive technology — forced either to use English-language tools that undermine their immersion education or to go without effective communication support entirely.
The development of Geabaire also has implications for the broader Irish language revival project. One of the persistent challenges facing Irish-medium education is the perception that the language is incompatible with modern technology and contemporary life. A high-quality, freely available Irish language app that addresses a genuine and pressing need challenges that perception directly and demonstrates that Irish can be a language of innovation as well as tradition.
Local Impact
For families in Dublin, Cork, Galway, and the Gaeltacht regions of Donegal, Mayo, and Kerry, the practical impact is immediate. Children who attend Gaelscoileanna and have complex communication needs will now have access to a tool that supports their education rather than working against it. In the Gaeltacht areas, where Irish is the community language as well as the language of instruction, the significance is particularly acute — these are children for whom Irish is not a second language but their primary means of engaging with the world around them. The ADAPT Centre at Trinity has indicated that it will work with the National Council for Special Education to ensure that Geabaire is integrated into the support plans of eligible children across the country.
What's Next
The research team is continuing to develop Geabaire, with current work focused on expanding the bank of synthetic voices available within the app and enhancing the expressivity of the speech output so that users can choose a voice that reflects their personal identity and regional dialect. A formal evaluation of the app's impact in educational settings is planned for the 2026-27 school year, with results expected to be published in early 2028. The team has also been approached by researchers working on Welsh and Basque language assistive technology who are interested in adapting the Geabaire model for their own linguistic contexts.
