对于那些说话或写作能力有限或根本没有能力的人来说，交际能力的发展是不可思议的，因为它是如此的不可能。然而，增强和替代性沟通（AAC）选项允许许多人实现交际能力。与魔法一样，使用AAC的成本部分是隐藏的。设备和材料的成本是显而易见的;然而，指导和学习的成本却不是。这些费用的记录和传播将使审计咨询委员会的潜在用户和公共政策规划者能够更准确地估计和管理审计咨询委员会干预措施的总体费用。
The development of communicative competence by persons who have limited or no functional speaking or writing skills is magical in that it is so improbable. Yet, augmentative and alternative communication (AAC) options have permitted many individuals to achieve communicative competence. As with magic, the costs of AAC use are partially hidden. The equipment and material costs are obvious; however, the instruction and learning costs are not. The documentation and dissemination of these costs will permit potential AAC users and public policy planners to estimate and manage the overall costs of AAC interventions more accurately.
