I had a TA at school who was blind and was excellent at helping CS students debug and fix their class projects. He helped me a number of times and was generally able to find bugs very quickly.

While I don't know the name of the program of he used, my vague recollection is that it read aloud the contents of whatever line he had the cursor on, a good deal faster than a human would speak it (I actually found the text to be read too quickly for me to follow by listening - I needed to read it myself).

I actually found this article about him on the Internet:
