Recognised in 1999. Still waiting to be delivered.

Thailand named Thai Sign Language the national language of Deaf people before almost anyone else in the region, and runs a real relay service. There are 571 interpreters for the whole country. We have no partner in Thailand yet. That is what this page is for.

This page in TSL

A Deaf creator from Thailand signs this page, credited by name. Recording begins when we have a local creator — that is one of the things we are looking for.

Where Thailand stands

Closer than it looks.

In plain words

Here is who lives here and what reaches them. Some of it already works. Where a number is missing, we say so instead of guessing.

Every figure carries its source and says what it measures — surveys that ask people and clinics that test people produce different numbers, and we will not blur them together. Send us a better source and we will use it.

Interpreters
About 200 registered SourcePress-reported rather than published by the department's own registry. The government has announced 77 new provincial posts and fast-track training for 180 more interpreters across 2025–2026. This is among the widest interpreter-to-population gaps of any country surveyed.Department of Empowerment of Persons with Disabilities, reported by Bangkok Post, 2025

The gap, in one number

There are not enough interpreters. There were never going to be.

Interpreters are skilled professionals and there will never be enough of them to cover every film, lesson, clinic visit and news bulletin. That is not a criticism of interpreters — it is arithmetic.

Recorded sign language does not replace an interpreter in a hospital room. It covers the enormous amount of content no interpreter was ever going to be booked for — so the interpreters go where only a person will do.

1 : 1,993

One qualified interpreter for every 1,993 Deaf and hard-of-hearing people.

398,659 people registered with hearing or communication disabilities ÷ 200 registered interpreters. We show the arithmetic because the two numbers come from different places.

Promised, and delivered

Compliant isn't the same as understood.

Thailand has already written much of this into law. The distance between the promise and the ordinary day is where we work.

  1. The law says

    Deaf people must be able to reach services through sign language.

    NBTC — Thai Telecommunication Relay Service

    And it works

    A national relay service does exactly that, through interpreters, by video, at well over a thousand calls a day. It is real and it is used.

  2. The law says

    People with disabilities have the right to a sign language interpreter, free of charge.

    Persons with Disabilities Empowerment Act B.E. 2550 (2007)

    In practice

    571 interpreters are registered for 432,495 registered Deaf people. The right exists; the arithmetic does not support it. The government is adding one post per province.

  3. The law says

    Thai Sign Language is the national language of Deaf people.

    Ministry of Education resolution, August 1999

    In practice

    Recognised in 1999, and still not standard on the news, in classrooms, or across public services. Recognition raised the floor for argument; it did not build the service.

An ordinary day

Today, and when this works.

Not emergencies. Ordinary days, in this country, as they are now — and as they are somewhere else already.

  1. The evening news

    Today

    Sign language appears on some broadcasts, not as a matter of course. Recognition in 1999 did not put an interpreter on the schedule.

    When this works

    The bulletin signed every night, and the programmes after it.

  2. School

    Today

    The law gives a right to an interpreter free of charge. With 571 interpreters nationally, whether a Deaf student gets one depends on which province they live in.

    When this works

    Lessons recorded in Thai Sign Language by Deaf teachers, available in every province at once.

  3. Calling for help

    Today

    A national relay service connects Deaf callers through interpreters by video, over a thousand calls a day. It has also gone dark for three months when funding lapsed.

    When this works

    This one already works. What it needs is funding that does not stop — the service proved the demand years ago.

  4. Finding an interpreter

    Today

    571 registered interpreters serve 432,495 registered Deaf people. The government is adding one post per province, which is 77 more.

    When this works

    Recorded Thai Sign Language covering what is the same for everyone, so those interpreters go where only a person will do.

None of the right-hand column is hypothetical. Every part of it already works in some country — a signed news bulletin, an emergency line that answers without a voice, Deaf teachers in a Deaf school. Just not all of them in the same one.

An ordinary day, signed

This section matters most to people who do not read the written language, so it is first in the signing queue for this country.

What would change here, starting now

Months, not years.

Three things a local partner and a11y could put in front of people quickly — each one already built, just not here yet.

  1. Content people actually watch, in TSL

    Deaf creators here sign films, lessons and public information, and are paid for it. The delivery layer already exists — what it needs is this country's sign language in it.

  2. One city, one service

    A single public service — a clinic, a council channel, a cinema — made accessible end to end, with the receipts published. Elsewhere that has meant ordinances passing and budgets moving.

  3. A signed news digest

    A regular summary in TSL, made by paid local Deaf creators. Small enough to start this year, and it is how a creator community starts earning.

These are descriptions of a first project, not work we have done here. We have no partner in Thailand yet.

Who this gets built with

We would not be arriving to an empty room.

Deaf communities here have been organising, teaching and campaigning for decades. Anything we do belongs alongside them, not in front of them.

These organisations are not a11y partners — they are the people already doing this work here. If we come to this country, it should be alongside them.

Looking for a partner.

No local partner yet. We are looking for a Deaf-led organisation, a broadcaster or a province to work with here.

    An association, a school, a broadcaster, a creator. A name and a reason is enough.

    You may already have the law and the money. What is missing is the service.

What happens after you write

  1. Write in whichever language suits you — text, or a video in TSL.
  2. We reply within five working days, in the form you used. Deaf staff and interpreters read the video messages.
  3. We look at one service together, and say honestly whether we can help with it.

What a11y brings: the delivery layer, payment for creators, and what worked elsewhere. What a local partner brings: the language, the community's trust, and judgement about what this country needs first. What we will not do: replace interpreters with software, use unpaid community labour, or claim work we have not done.

Know your rights

What you are entitled to here.

In plain words

These are things the law already says you can ask for. If you have been refused any of them, that refusal was against the law — not a favour you were denied.

Written plainly, with the law behind each one linked as a receipt. This is the part of the page we would most like a local Deaf organisation to check and correct.

Tell us what we got wrong

Your language

Recognised as the national language of Deaf people in Thailand since 1999.

A Ministry of Education resolution signed in August 1999 on behalf of the government named Thai Sign Language the national language of Deaf people — one of the earliest such recognitions anywhere in Asia.

Ministry of Education resolution, August 1999

In an emergency

Yes. A national relay service connects Deaf people through sign language interpreters, and carries well over a thousand calls a day.

The Thai Telecommunication Relay Service runs as part of the Universal Service Obligation, with interpreters relaying calls by video. Its funding is periodic rather than permanent, and a three-month interruption left Deaf callers without it.

What opens a full page

This page grows when three things are true.

  1. A local Deaf creator has recorded this page in Thai Sign Language — named and paid.
  2. There is at least one real, local fact with a source behind it.
  3. Someone owns keeping it current.

Until then it stays honest about what it is: the situation, and an open invitation. All countries · See a full country page
