Purpose: The development of culturally and linguistically appropriate resources to support communication interventions for underserved communities is an urgent necessity. The purpose of the study was to obtain stakeholder feedback on vocabulary items from a Sepedi core vocabulary list developed as a resource for vocabulary selection for augmentative and alternative communication (AAC) systems, and to expand the list based on stakeholders’ vocabulary recommendations. Method: A questionnaire was used to obtain the ratings of 57 stakeholders regarding the importance of including 155 Sepedi words from the Sepedi core vocabulary list on an AAC system for a child with receptive language skills at the level of a 4-year-old or higher. Stakeholders also suggested additional words to include on the system. Result: All words were rated as important or very important. However, there was a statistically significant inverse relationship between the average frequency of occurrence of words belonging to a specific category and the average importance rating that stakeholders assigned to words in that category. A total of 48 words were additionally suggested by three or more stakeholders. Conclusion: Stakeholder ratings validated the list as relevant to consult in vocabulary selection for Sepedi AAC systems for children. Stakeholder-suggested words may be a useful supplement to this list.
