it helps augment it. They can program whatever words you want. They update Alex's reguarly to incorporate his studies. He really helps him alot. He loves it! It does talk for him, says the word. I'm not sure when all they use it though... probably all the time and he can use it when needed.
edited to add: they have all his classmates and teachers pictures programmed in as well.
