Quality

Quality standards and frameworks for AACs are limited due to the diverse and complex nature of AAC needs, the interdisciplinary nature of AAC provision, and the relatively recent evolution of high-tech AAC provision. High-tech AAC devices are governed by quality standards depending on the type of device, such as mobile phone accessibility standards for mobile-phone-based AAC solutions. Despite the complexity of communication standards, core vocabulary has played a crucial role in enhancing AAC solutions. Core vocabulary consists of essential words that are central to language use and applicable across various contexts. Examples include pronouns and verbs. Efficiently incorporating core vocabulary into AAC systems is recommended to benefit users. 7
