Yes, there is hardware and software that can be used to help with your communication.
There are large specialist firms that design and supply tech that helps people with complex speech and language needs to communicate; known as “augmentative and assistive communication” (AAC) solutions. We also use applications that can be downloaded to a tablet or smartphone that are developed by small independent software houses. Depending on your needs some software may be available in free limited functionality apps or more costly hardware and setups may be appropriate. Some NHS centres and charities can assist with equipment or funding.
We use iPad and have most full software applications that we use in therapy and training so help clients get use to a service before purchasing is possible, though some helpful apps are only a few pounds.
