Augmentative and Alternative
Communication (AAC)
AAC refers to methods that are used to support or replace speech for individuals who have difficulties with communication. AAC most often is referring to voice output communication programs on high-tech devices (e.g., an iPad). AAC systems can and should be individualized to meet the unique needs of the user.
​
Assessment
An AAC assessment typically starts with the SLP consulting with parents and familiar communication partners regarding the client's history and current communication abilities and needs. Next, the SLP will observe and interact with the client. Assessment measures can be formal or informal, and information is often gathered over multiple visits.
Different AAC tools can be trialed in order to determine what type of system or program is the best fit for the individual. Assessment of AAC needs takes into account a variety of factors, such as speech, language and literacy abilities, vision and fine motor skills, communication environments and activities, and long-term and short-term goals.
Intervention
Following an AAC assessment, the SLP can provide additional support to facilitate the customization and introduction of the selected AAC system.
​
Training can be provided directly to the client through weekly therapy sessions as needed. Intervention should also involve caregiver training, coaching and education in order to support the use of the AAC system at home, at school and in the community.
​
Communication needs and abilities often change over time, and re-evaluation of AAC needs should be considered in order to ensure that the AAC system continues to be the best fit.
