Types of AAC Devices

When it comes to augmentative and alternative communication (AAC) devices for individuals with autism, there are various options available to support their communication needs. Two common types of AAC devices are voice output communication devices and visual communication books.

Voice Output Communication Devices

Voice output communication devices, also known as AAC devices, have been utilized for 50 years to assist individuals with developmental and acquired disabilities in successful communication. These devices hold great promise in helping nonverbal individuals with autism overcome their communication challenges.

Voice output communication devices provide sensory feedback through auditory output, assisting in the development of receptive and expressive language skills in children. These devices help learners progress from basic cause/effect interactions to learning new words, increasing vocabulary, and eventually combining words to form phrases and sentences for communication.

These devices come in various forms, ranging from dedicated communication devices with specialized software to tablets or smartphones with AAC applications. The software on these devices often includes customizable symbol libraries, text-to-speech capabilities, and the ability to save and recall commonly used phrases.

Visual Communication Books

Visual communication books, sometimes referred to as communication boards or picture-based systems, are another type of AAC device commonly used for individuals with autism. These books consist of pages or boards that contain visual symbols or pictures representing different words, objects, or actions.

Visual communication books provide a visual representation of language, allowing individuals with autism to communicate by pointing to the appropriate symbols or pictures. These books can be customized to suit the individual's specific communication needs, including their vocabulary and the topics they commonly encounter.

The use of visual communication books can support individuals with autism in expressing their wants, needs, and thoughts. It helps facilitate communication by providing a visual reference that aids comprehension and expression.

Both voice output communication devices and visual communication books serve as valuable tools in promoting communication for individuals with autism. The choice between these devices depends on factors such as the individual's communication abilities, preferences, and specific communication goals. AAC professionals can assist in assessing the needs of individuals with autism and recommending the most suitable AAC device to enhance their communication skills.

Implementing AAC Devices

Once an AAC device has been selected for an individual with autism, implementing it effectively is essential for promoting successful communication. This section will explore two crucial aspects of implementing AAC devices: customization of devices and setting realistic expectations.

When choosing an AAC device for someone with autism, it is important to consider customization options. The device should allow for personalization with custom icons, words, and phrases that are meaningful and relevant to the individual's communication needs and preferences. This customization ensures that the device reflects the individual's unique communication style and facilitates their ability to express themselves effectively.

Customization can involve programming the device with vocabulary specific to the individual's daily life, interests, and activities. It may also include the use of visual supports, such as photographs or symbols, that are familiar and meaningful to the individual. By tailoring the AAC device to the individual's preferences and experiences, it becomes a more powerful tool for communication.

Setting Realistic Expectations

When using an AAC device, it is essential to set realistic expectations. Progress may be gradual, especially in the early stages of implementation, but consistent use of the device can lead to improvements in communication and overall quality of life. It is important to remember that every individual is unique, and the rate of progress may vary.

Setting realistic expectations involves recognizing that learning to use an AAC device effectively takes time and practice. It is a skill that requires ongoing support and encouragement from caregivers, educators, and speech and language therapists. Patience and consistent use of the device in various settings can help individuals with autism gradually become more comfortable and proficient in their communication.

Working closely with a speech and language therapist is crucial during the implementation process.

AAC Interventions for Autism

In the realm of autism communication, AAC (Augmentative and Alternative Communication) interventions play a vital role in supporting individuals with autism who have difficulty with verbal speech. These interventions encompass various modalities that can replace or augment a person's speech and existing communication skills. Two key AAC interventions for individuals with autism include teaching request making and supporting language development.

Teaching Request Making

AAC interventions have proven to be effective in teaching children with autism to make requests and reducing challenging behaviors. The Picture Exchange Communication System (PECS), aided AAC, and speech generating devices (SGD) have shown the most evidence of effectiveness in this area [7].

The PECS involves using a series of pictures to enable individuals with autism to initiate communication by exchanging a picture card with a communication partner, indicating their request or desire. This intervention empowers individuals to make their needs known and promotes functional communication skills.

Aided AAC refers to the use of external aids, such as communication boards or electronic devices, to support communication. These aids can include symbols, pictures, or words that individuals can use to express their requests. By using aided AAC, individuals with autism can communicate their needs effectively and engage in meaningful interactions.

SGDs, or speech generating devices, are electronic devices that produce synthesized or recorded speech. These devices give individuals with limited or no speech the ability to generate spoken language by selecting symbols or typing on a keyboard. SGDs offer a powerful tool for individuals with autism to express themselves and engage in conversations.

Supporting Language Development

AAC interventions also play a significant role in supporting ongoing language development for individuals with autism. These interventions provide additional supports for comprehension and help extend language skills, even for those who are developing spoken language abilities [7].

AAC strategies can include incorporating different modalities, such as signs and symbols, to enhance language comprehension and expression. By using various visual and auditory cues, individuals with autism can better understand and communicate their thoughts, ideas, and feelings.

Moreover, training individuals in the child's social environment, such as family members, teachers, or peers, to support the use of AAC can facilitate language development. By creating a supportive and inclusive communication environment, individuals with autism can practice and reinforce their language skills in real-life situations.

It is important to individualize AAC interventions to meet the specific learning needs and preferences of children with autism. This may involve incorporating different modalities of AAC, such as signs and symbols, and training individuals in the child's social environment to support the use of AAC. Early consideration of AAC interventions within a comprehensive intervention program is crucial, and further research is needed to explore the broader outcomes and effectiveness of AAC interventions for children with autism.
