NOTE This document includes definitions that will be used in other parts of ISO/IEC 20071m but that are not necessarily used in this document.
This document recognizes that AAC can be delivered on various ICT devices and the importance of consistency for users across devices. It applies to AAC software and not the devices on which the software is used.
