    My [Thai] wife has trouble understanding people with strong accents. Scottish and Indian accents are the worst. I’d like to see how well this stands up to accented users.

    In one course, I had an electronics teacher who told us to use the “nouns”. We were all confused, until he told us to use them, to find the “un-nouns”. Then it finally clicked: knowns, unknowns.

    Easy, there is even a small tutorial on adaptation which you can use to raise the accuracy for accented speech:
