Augmentative and alternative communication for Aboriginal Australians: Developing core vocabulary for Yolŋu speakers

Area of Science:

• Linguistics
• Indigenous Studies
• Assistive Technology

Background:

• Yolŋu people in Arnhem Land face Machado-Joseph disease, leading to speech loss.
• There is a need for augmentative and alternative communication (AAC) systems in Yolŋu languages.

Purpose of the Study:

• To develop a culturally responsive process for creating a core vocabulary list for Yolŋu adults with Machado-Joseph disease.
• To inform the design of AAC system prototypes for Yolŋu users.

Main Methods:

• Participatory action research involving Yolŋu and Balanda (non-Aboriginal) researchers.
• Collaborative analysis of language samples and group discussions to select vocabulary.
• Utilized the Yolŋu metaphor Gulaka-buma ('Harvesting yams') to represent the research process.

Main Results:

• A core vocabulary list of 243 Yolŋu words and morphemes was created.
• Identified three key themes regarding cultural and linguistic considerations for vocabulary selection.
• Highlighted the importance of language as a vehicle for culture and identity.

Conclusions:

• Culturally responsive processes are crucial for developing effective AAC vocabulary for Indigenous populations.
• Integrating cultural and linguistic factors enhances AAC system relevance and usability.
• Language is integral to Indigenous culture and identity, necessitating its preservation in communication tools.
