ETS Praxis Audiology Practice Test

Phonetically balanced word lists are designed so the set of test words represents English phoneme usage fairly, providing a reliable measure of how well someone recognizes real words across the speech spectrum. The Northwestern University Test No.6 is a standard monosyllabic word list that is explicitly used for open-set speech recognition testing in adults and is typically presented at multiple intensity levels to map performance as loudness changes. This combination—open-set responses (the listener can say any word) with a phonetically balanced set and testing across several intensities—is why NU6 is the best answer. Other options serve different purposes: the WIPI is a closed-set, picture-based test; the PB-K is a pediatric phonetically balanced list; and CID W-1 is another PB list but is less commonly described for open-set testing across multiple intensity levels in standard practice.
