In what context is AAC considered to be alternative?

AAC, or Augmentative and Alternative Communication, is considered "alternative" in the context where it replaces speech that is absent or not functional. This designation highlights situations in which an individual does not have the ability to produce understandable speech due to various conditions, such as severe speech disorders, neurological impairments, or disabilities affecting their communication abilities. In these cases, AAC serves as the primary mode of communication rather than a supportive tool, making it essential for the user to convey their thoughts, needs, and feelings effectively.

In contrast, when AAC is used to supplement existing speech, it enhances communication but does not replace the verbal abilities the person possesses. Similarly, when AAC complements reading abilities, it facilitates literacy development but does not serve the same function as providing an alternative means of communication. Lastly, AAC utilized temporarily during recovery pertains to a transitional phase, where traditional speech might be restored, thus not fitting the criteria for being an alternative mode of communication.
