Overview

Selecting vocabulary to use within an alternative augmentative communication system (AAC) is an important part of each system and can impact the user experience. Thoughtful consideration of the vocabulary that is chosen for an AAC system can help ensure that it is appropriate to the AAC user’s needs and lifestyle. Vocabulary selection can also help support the AAC user’s growth and development of their language and communication skills throughout their lifetime.

This module will discuss five themes that are important in evidence-based research when selecting vocabulary for an AAC system.

This module is only a guide. Selecting vocabulary within an AAC system is an ongoing process. It should continue to be reviewed and updated. This will help to ensure it remains relevant and beneficial for the AAC user and their environment.

The five themes are:

1.        Individual preferences and interests 

2.        Brown’s stages of communication 

3.        Assessment and evaluation tools

4.        Types of vocabulary and their usage  

5.        Person-centred decision-making

Note: Collaboration and cultural considerations (see person-centred decision-making) are ongoing and should be included in the whole process on how to select what vocabulary to use within an AAC system.
