Personally I don't expect this to be of much use to me. I find the task of translating thoughts into words to be more strenuous than it is for others, and so I expect this to be more distracting than helpful. I played games where I tried to subvocalise all of my thoughts the way some people have interior monologues and they support this conclusion. I believe I have a fairly good working memory (for instance, I can play blind chess) and so I don't as as much value in an external aid. Other people are commenting based on their own personal experience and feelings, so I think I can trust my own gut feeling in terms of how this will work out for me.
