Unfortunately, this device did not work for me. I used the DynaVox for about five years, though, before I found funding for something else. Now I am back to a Minspeak-based device. Vocational rehabilitation is paying for a Pathfinder. I am trying to use Unity and break my old habit of spelling all words out.
Unity is a good software program.
I like the flexibility of the program. Throughout my school years and now beyond, I use augmentative communication to communicate with people who have difficulty understanding my own natural speech. People who have known me for a while can understand my natural speech almost all the time. Strangers usually have no clue what I am saying unless I use augmentative communication. I have used these devices to interact with teachers, classmates, employers, coworkers, strangers and friends.
