An integral component of a language-based augmentative and alternative communication (AAC) system is providing vocabulary typical of fluent native language speakers. In the absence of reliable and valid research on Malay vocabulary for AAC, this descriptive study explored the validation process of vocabulary selection and organization for a 144-location manual communication board. An hour of aided language samples (talking while pointing to a prototype display) followed by self-administered surveys were gathered from four typical native Malay speakers (n=4), aged between 22 to 36 years at the University of Pittsburgh. Vocabulary frequency analysis, word commonality, and overall perceptions and feedback on the prototype display were compiled and analyzed. A total of 1112 word tokens and 454 word types were analyzed to support preliminary validation of the selected vocabulary and word organization of the prototype. Approximately 40% of the words on the display were used during the interview and the top 20 words were reported. Findings also suggest the importance of morphology and syntax considerations at early design stages. The positive overall perception of the display including vocabulary selection, the cultural and ethnicity appropriateness, and suggestions for system improvement were confirmed by the usability survey. Minimal rearrangement of the icon display needs to be performed to improve the usability of the system. Thus, the study findings support the early Malay manual communication board for AAC intervention. However, the limitation of the sample size and additional research is required to support a final display that optimizes vocabulary and morphosyntactic organization of a manual communication board in Malay.
