Is Asr Accurate Enough For Automated Reading Tutors, And How Can We Tell?

We discuss pros and cons of several ways to evaluate ASR accuracy in automated tutors that listen to students read aloud. Whether ASR is accurate enough for a particular reading tutor function depends on what ASR-based judgment it requires, the visibility of that judgment to students and teachers, and the amount of input speech on which it is based. How to tell depends on the purpose, criterion, and space of the evaluation.
