The jury is still out on Constant Therapy from my viewpoint. Best part is that it is interactive and hears what he is saying so it checks his clarity and adjusts as he goes along, but he could not handle it on his own at the default level. We learned how to set the speed down to much slower and we haven’t tested that enough yet but it appears much better. You can get a free week trial but then it auto charges $29.99 monthly so watch that you use it immediately to make your own judgment. I called them to get better help and they were very responsive.
I have heard of other programs also but haven’t tried those yet.
We LOVE Luminosity.com and it has been very beneficial but does not contain a speech training game.
