Communication Choices : Without Speaking

People need a communication system to deliver messages to each other.  There are two types of communication, which are verbal and non-verbal. In verbal communication, we use voice and articulation; meanwhile in non-verbal communication we do not need them.

What is AAC?

Augmentative and Alternative Communication (AAC) is one type of non-verbal communication. We use AAC to deliver our messages without voicing it out. Facial expression, body gestures, use of pictures, symbols and writing are  just a few types of non-verbal communication.

Augmentative communication is used to supplement limited speech, language and communication abilities. Alternative communication on the other hand, is used to replace verbal communication in an individual who is unable to speak.

Who needs AAC?

AAC can help  Individuals who have  difficulties or are unable to effectively use verbal means of communication to express their needs. Some children and adults with speech, language and communication difficulties rely on AAC to communicate.  Among those who may need AAC are individuals with:-

  • Autism

  • Down’s Syndrome

  • Cerebral Palsy

  • Intellectual Challenges

  • Brain Injury

  • Cerebral Vascular Accident / Stroke

Types of AAC

AAC can be divided into two types which are:

  • Unaided AAC

  • Aided AAC

Unaided AAC

  • This type of communications does not require any equipment or support materials. It is totally dependant on the person’s physical ability.

  • For example, people can use sign language, facial expressions and body gestures to express themselves.
