augmentative and alternative communication (AAC)

The ways in which people communicate other than oral speech. Augmentative communication refers to communications techniques in addition to speech, while alternative communication refers to techniques used in place of speech. The American Speech-Language-Hearing Association refers to both no- or low-tech types of AAC and high-tech types of AAC.

No-tech and low-tech types of AAC include:

  • Gesturing with hands and body
  • Facial expressions.
  • Writing or drawing.
  • Using a picture of letters to spell (by pointing to them or moving them)
  • Pointing to photos, pictures, or written words.

High-tech types of AAC include:

  • Communication with a communication board, iPad or tablet.
  • Using a computer or AI to create audible speech (speech-generating technology).
