Voice AI and Irish Language Duties in Northern Ireland

Most enterprises building a voice AI channel treat language as a settings toggle. In Northern Ireland, for a large and growing group of organisations, it is becoming a statutory duty. The Identity and Language (Northern Ireland) Act 2022 gave the Irish language official recognition, created an Irish Language Commissioner, and set up a system of best practice standards that public authorities will have to reckon with. The Commissioner took office in November 2025. The standards are being drafted now.

That timing matters, because the part of a public service that is hardest to make bilingual is the automated one. A bilingual leaflet is a translation job. A voice agent that has to recognise Irish, respond in Irish, route an Irish speaker to the right place, and fail gracefully to a human when it cannot cope is an engineering job, and it is one most bodies have not scoped. Procurement cycles for a voice channel run longer than the window that is now left before the standards land.

This guide sets out what the duty actually is, who it binds, when it bites, whether a voice agent can handle Irish at all, and what a Northern Ireland public body should specify in a procurement today. It is written for the operators who will have to answer to the Commissioner, not for lawyers. Across the wider enterprise market, McKinsey's 2025 State of AI found that around 88 per cent of organisations now use AI somewhere but only about 6 per cent capture material EBIT impact from it, and language duties are exactly the kind of detail that separates a deployment that works from one that is quietly non-compliant.

What are the Irish language duties on public bodies in Northern Ireland?

The Identity and Language (Northern Ireland) Act 2022 inserted a new Part 7B into the Northern Ireland Act 1998 that gives the Irish language official recognition, provides for an Irish Language Commissioner, and requires public authorities to have due regard to published best practice standards. The core duty is set out in the new section 78O. The standards are still being developed, so the duty has no detailed content yet, but the framework is now law.

The operative wording is precise about who must do what. Section 78O(1) provides that "A public authority must, in providing services to the public or a section of the public in Northern Ireland, have due regard to any published best practice standards." Two things follow from that single sentence. First, the duty is a "have due regard" duty, not an absolute requirement to deliver every service in Irish; it is closer to the public sector equality duty in shape than to a hard mandate. Second, it only bites against published standards, and none have been published yet.

Section 78O goes further than a reading obligation. A public authority must also prepare and publish a plan setting out the steps it proposes to take to comply, and revise that plan when the standards are revised. In practice that means every in-scope body will eventually have to state, in a public document, how its channels reflect the standards. A voice channel that cannot handle Irish, or that handles it badly, becomes a visible line in that plan rather than a private engineering gap. Getting ahead of it is far cheaper than retrofitting, which is the same logic behind our approach to placing AI in regulated services.

Who does the Northern Ireland Irish language duty bind?

The Irish language duty in section 78O binds public authorities in Northern Ireland, not private companies and not technology vendors. It applies to a body when it provides services to the public in Northern Ireland. A private enterprise selling a voice AI platform is not caught by the statute directly. Its exposure is contractual: if it supplies the automated channel a public body relies on, the body's duty flows down through the procurement contract, not through the Act.

This distinction is the one most commentary gets wrong, so it is worth stating plainly. The Irish Language Commissioner has no power to fine your company for a monolingual product. The Commissioner's powers run against public authorities: guidance, monitoring, and the investigation of complaints about how those bodies serve Irish speakers. Around 100 public bodies in Northern Ireland fall within that orbit, according to RTÉ's reporting of the appointment. If you are one of them, the duty is yours, and public bodies already used to transparency obligations such as freedom of information will recognise the shape of a "have due regard" duty. If you sell to them, the duty reaches you only as a clause in the contract and a requirement in the tender, which is why public sector procurement is where this gets decided in practice.

When will the Irish language best practice standards be published?

No date is fixed in law. The Irish Language Commissioner, Pol Deeds, took office in November 2025 and his team is now researching before a formal consultation. The standards must then be submitted to and approved by the First Minister and deputy First Minister before publication. Deeds has said he intends to present them before the end of 2026, but that is his stated intention, not a statutory deadline, and approval is outside his control.

The sequence is set by section 78M of the Act. The Commissioner prepares written best practice standards, submits them to the two ministers, who may approve them with or without modifications, and only then does the Commissioner publish them. Because the "have due regard" duty in section 78O attaches to published standards, an in-scope body has no detailed obligation today. What it has is a runway, and a shrinking one. The Commissioner has signalled that he wants to submit the standards before the end of 2026, and the honest planning assumption is that they could be published within the current mandate, that a voice channel takes months to procure and build bilingually, and that the two timelines are already overlapping. Treating the absence of published standards as permission to do nothing is the trap. The same AI operating model discipline that governs any regulated rollout applies here: build the capability before the rule is enforceable, not after.

How well can a voice agent actually understand and speak Irish?

Irish is a low-resource language for speech technology, so a voice agent will not handle it to the same standard as English out of the box. English benefits from vast training data; Irish has far less, and carries three dialects, with Ulster Irish the most relevant in Northern Ireland. A voice agent that can greet a caller in Irish is easy. One that understands a request in Ulster Irish and gets the details right is much harder.

The gap between a polished greeting and genuine comprehension is where compliance quietly fails, so the practical consequences are worth spelling out. Automatic speech recognition for Irish is weaker and more sensitive to dialect and code-switching, where a caller moves between Irish and English mid-sentence, than the English models most platforms are tuned for. Text to speech in Irish can sound stilted if the voice was not built for it. Terminology matters too: place names, personal names, and official terms follow conventions maintained by bodies such as Foras na Gaeilge, and an agent that mangles them reads as tokenism rather than service. This is why the honest design pattern is a genuine bilingual capability with a fast, clearly signposted route to an Irish-speaking human when the agent reaches its limit, the same escalation logic that governs any voice AI agent in a sensitive setting. A convincing Irish greeting bolted onto an English-only system is worse than an honest offer of a callback.

How does Northern Ireland's regime differ from Wales and Scotland?

Northern Ireland's regime is earlier in its life and softer in legal shape than Wales's, and it is not yet a system of enforceable standards. Wales has had the Welsh Language (Wales) Measure 2011 and a mature set of Welsh Language Standards for years, backed by a Commissioner with real enforcement powers. Northern Ireland has the statutory framework and a Commissioner, but no published standards, so a body's obligation today is to prepare, not to deliver a fixed service level.

For the detail on each neighbouring regime, the sibling guides go deeper than there is room for here: how the enforceable Welsh Language Standards shape a bilingual voice agent, and how Scotland's Gaelic language plan regime works under its own recent legislation. The design lesson transfers cleanly: a body that builds a genuinely bilingual channel for one regime has most of the architecture it needs for another. Northern Ireland adds a wrinkle the others do not have, though. It is a two-language duty environment. Alongside the Irish Language Commissioner, a Commissioner for Ulster Scots, Lee Reynolds, was appointed under the same Act, and Ulster Scots has its own recognised community. A voice channel serving Northern Ireland cannot assume a single minority language.

The scale is not trivial. The 2021 Census recorded that 12.4 per cent of the population aged three and over, some 228,600 people, had some ability in the Irish language, up from 10.7 per cent, or 184,900 people, in 2011. A further 10.4 per cent, around 190,600 people, had some ability in Ulster Scots. These are not equivalent measures of fluency, but they are the numbers the Commissioner and the ministers will have in mind when they set what "reasonable" service looks like.

What should a Northern Ireland public body build before the standards land?

Build a bilingual capability and the governance to prove it, not a demo. Because section 78O will require a public authority to publish a compliance plan, the safest position is to describe honestly how your voice channel offers Irish, how it routes and escalates, and how you measure whether Irish speakers get an equivalent service. That is an operating problem as much as a technical one, far cheaper to design in now than to retrofit.

Concretely, four things belong in the plan and in any procurement. First, an explicit language-choice step early in the call, so the caller is offered Irish rather than having to demand it. Second, a real escalation path to an Irish-speaking human, with the wait and the coverage measured, not assumed. Third, a data position: the caller's language preference is personal data, and you need to be clear on who is the data controller of it and how it is stored, which sits alongside your wider UK and EU compliance posture. Fourth, an honest disclosure that the caller is speaking to an AI system, which is a separate duty covered in our guide to AI disclosure to callers. Bodies already running voice for council and local government services have most of the plumbing; the Irish layer is an addition, not a rebuild. The equivalence test echoes the accessibility duties under the Equality Act, which cover disabled callers rather than language but demand the same evidence of equivalent service. Our AI execution office exists precisely to hold that kind of standing delivery commitment across a runway like this one.

The same diagnostic logic underpins our AI placement diagnostic, a fixed-fee assessment used before any deployment commitment, which for a public body means knowing whether an Irish voice channel is realistic before it is written into a tender.

What is the best voice AI platform for Irish language services in 2026?

No platform offers turnkey, production-grade Irish voice the way the market offers English, so the honest answer in 2026 is that "best" depends on how much genuine Irish-language demand you carry. For a body with meaningful Irish call volume, the right choice is a governed, bilingual-by-design build with a documented compliance plan, which is where a platform like Dilr Voice or PolyAI, with proper delivery, fits. For very low volume, a well-signposted Irish-speaking callback beats a weak Irish agent.

That verdict cuts against some vendors, and deliberately. Self-serve tools such as Vapi, Retell AI, Bland AI and Synthflow are strong for fast English deployments, but a low-resource language with a dialect requirement and a public-sector compliance plan attached is not their sweet spot, and they will happily let you ship an Irish greeting with no Irish comprehension behind it. There is a real scenario where a competitor wins: if you genuinely serve almost no Irish speakers and your plan says so with evidence, a lighter English-first tool with a clear callback route beats an expensive bilingual build you cannot justify. The test is not which platform has the best demo; it is which can be described truthfully in a document the Commissioner may one day read.

Do private companies have to offer an Irish language voice service?

No. The duty in section 78O of the Northern Ireland Act 1998 binds public authorities providing services to the public in Northern Ireland, not private companies. A private business faces the Irish language requirement only if it supplies or acts for an in-scope public body, in which case the obligation reaches it through the contract and the tender rather than through the Act itself. There is no general statutory duty on private firms to offer an Irish voice service.

Does a Northern Ireland public body have to offer Irish right now?

Not to a fixed standard yet. The "have due regard" duty attaches to published best practice standards, and none have been published, so there is no detailed service level in force today. A body still cannot ignore the framework: it should be preparing, because the Commissioner is in office, the standards are being drafted, and section 78O will require a published compliance plan once they land. Doing nothing until then leaves no time to build a bilingual voice channel.

What about Ulster Scots?

Ulster Scots has its own recognised status and its own Commissioner, Lee Reynolds, appointed under the same Identity and Language (Northern Ireland) Act 2022. It is a distinct regime from the Irish language one, with its own community and its own eventual expectations. A voice channel serving the Northern Ireland public should treat the environment as multilingual rather than assuming Irish is the only minority language in scope, and should design its language-choice and escalation logic with that in mind.
