The 15th Theoretical Issues in Sign Language Research (TISLR15) International Conference underway in Addis Ababa

The four-day conference, the first of its kind on the African continent, aims to enhance and share knowledge on sign linguistics; provide information for decision-makers; and advance the education and rights of deaf communities.

Today, an estimated 1.3 billion people—nearly 16% of the global population—live with some form of disability. Among them, millions rely on sign language as their primary mode of communication. 

In December 2006, the United Nations General Assembly adopted the Convention on the Rights of Persons with Disabilities, a landmark treaty that underscores the need to recognize and promote the use of sign language. Article 21 of the Convention explicitly calls on states to accept and facilitate the use of sign languages in official interactions, ensuring that persons with disabilities can access information on an equal basis with other.

In his address to the Conference, Dr. Ramiz Alakbarov, UN Assistant-Secretary General and UN Resident and Humanitarian Coordinator said, “sign language is more than a tool for expression—it is a bridge to education, employment, healthcare and full participation in society.”

“Across the globe, people who rely on sign language face discrimination, limited access to quality education, health services, employment, and underrepresentation in public life,” he said.

“It is our collective responsibility to eliminate these barriers and ensure that no one is left behind.”
