Machine translation
Translation engines trained for each language, able to work with very little data and respectful of its structures and cultural expressions. They translate to and from Spanish.

An open, non-profit technology ecosystem dedicated to preserving and empowering low-resource languages.
Authorized and validated by the speaker community.
What is VOCES?
VOCES seeks to protect, revitalize and promote Indigenous languages through digital empowerment and the development of technologies that create the conditions to use, learn, teach and pass on a language, making it part of everyday life.
It is not about archiving a language, but about making it present where life happens today: on the phone, at school, in public services and on the internet.
“A language existing in the digital world is not a cultural luxury: it is public infrastructure for its speakers' future.”
Developing state-of-the-art language technology in the service of Indigenous peoples.
Strengthening Indigenous peoples' own language institutions so their work can be sustained over time.
Laying the technological groundwork that lets peoples carry their language into the digital future.
Document, transcribe and preserve the living corpus of each language: voice and text.
Tools to learn, teach and pass the language on to those who come next.
Use it every day: at school, in healthcare, in public services, in the media and online.
The challenge
That is 26 languages a year. Half of the world's languages could disappear this century, and each one takes with it an identity, a worldview and a heritage that cannot be recovered.
556
Indigenous languages in Latin America and the Caribbean
38.4%
are in danger of disappearing
47%
of the languages endangered today were not 15 years ago
66
languages have fewer than 99 speakers today

For every 20 pages browsed on the web, one is in Spanish. It takes 125,000 to find one in Guarani, one of the Indigenous languages with the most presence online.
No Indigenous language of the Americas reaches the 0.1% threshold at which web content is measured. Artificial intelligence inherits that gap — and widens it.
Fewer than 5% of the world's languages can make the digital leap without deliberate intervention. The same technology that opened the gap can close it.
What we do
Our work starts from what speaker communities ask of us. These are the lines of work through which we respond.

Translation engines trained for each language, able to work with very little data and respectful of its structures and cultural expressions. They translate to and from Spanish.

Audio transcription and read-aloud in the language. It is the most important line of work for communities where transmission is oral and much of the corpus lives in the memory of its speakers.

On-site training with speakers, teachers and community authorities: how to use the tools, how to correct them and how to decide over the community's own data.
Building and curating parallel corpora, lexicons and recordings, with governance in the hands of the community.
Every tool is reviewed with speakers and ancestral authorities before it opens: relevance before speed.
Live translation for meetings, ceremonies and public-facing services at institutions.
Digital readers, school textbooks and apps to learn and teach the language, and for healthcare.
Digitizing and recording stories, songs and testimonies in digital archives that are accessible and protected by their own communities.
Programmatic access so schools, public services and third parties can build the tools into their own systems.
Translators
From community pilots to public tools in real use. Each translator opens only once its speaker community has validated it.
They already work with real users from the community, while the intercultural validation that decides when and how they open is completed.

Where we work
Each dot is a speaker community that chose to work with us. The work moves at the pace of each territory, not of the project's calendar.
How we work
Our hallmark is that the tools are co-created with speaker communities, respecting their protocols and their timelines. No version opens until its speakers have validated it.
VOCES is a non-commercial collaborative alliance, aligned with the International Decade of Indigenous Languages 2022–2032.

Translation, voice and writing trained with and for each language, designed to work even with very little data.
The data belongs to the communities: they decide what is collected, how it is used and who has access.
Built together on site with speakers, educators and community authorities, respecting protocols and timelines.
Eight stages, gone through once and then repeated in cycles of continuous improvement, always with the community at the center.
The community decides whether it wants to work with us, and on what terms.
A first concrete version that shows what is possible, before asking for anything.
Material provided by the community, corrections from speakers and translation of selected sentences.
Model training, gathering of additional material and tailored adjustments.
Testing in real settings, with real users and the relevant institutions.
The community sets the strategy: restricted, public or mixed access.
The tool stays in place, with local capacity to maintain it.
On top of translation, voice and writing, applications are built to revitalize, give access to and promote the language: education, health, media and public services.
A public good
One community using it takes nothing away from another: the same model serves schools, public services, researchers and creators.
It is the foundation on which others build new tools that we cannot yet anticipate.
There is no commercial return in a language with a few thousand speakers: if public policy doesn't do it, nobody will.
VOCES makes available the enabling factors needed to meet each community's real needs.
