looking for talking app

[nelly48237]

my brother is legally blind, but still have part of his eye sight. he has the touch pro 2, and he is able to use it by memorizing the keys on the keypad. while at the sprint store the other day, there was a guy in there that was partially blind like my brother. He had a touch pro 2, and he had a talking app on it that spoke for him. I forgot to ask him what the app was. Does anyone on here know what this app is? or what kind of talking app my brother could use on his phone? I could't find this in a search.... I would appreciate any help I can get on this issue. thanks
