Assistive technology for verbal communication, also known as augmentative and alternative communication (AAC) devices, was developed to help people with speech difficulties communicate verbally or face to face. These devices may be useful for a wide range of people, including those whose ability to speak has been affected since birth (such as autism, cerebral palsy, down syndrome), those who have lost their ability to speak due to medical problems (such as stroke or brain injury), and those who have temporary communication challenges.
Voice Output Devices (VODs) are AAC devices that supplement or replace speech, assisting persons with speech impairments in verbal communication.
AAC Apps & Software
Users can use AAC apps or software on their designated devices (i.e., tablet or computer), rather than specialized AAC devices, as their AAC AT as well as for other activities and tasks.
