AAC apps, or Augmentative and Alternative Communication applications, are software tools designed to help individuals with speech or language difficulties communicate more effectively. These apps can be used on various devices, such as tablets and smartphones, and often include features like text-to-speech, symbol-based communication, and customizable vocabulary. Many AAC apps cater to different needs and age groups, making them versatile for users ranging from children with autism to adults with stroke or other conditions affecting speech. By providing alternative ways to express thoughts and needs, AAC apps enhance communication and improve the quality of life for many users.
