The Nonsense Syllable Test© (NST) (also known as the Edgerton-Danhauer Nonsense Syllable Test) is considered similar to a word recognition or speech discrimination test. Watch the video demonstration below. (Scroll down.)
Several advantages of nonsense syllable materials over words include: increased analytic accuracy, less contamination by memory effects, less susceptibility to word familiarity effects, easier test construction and more sensitivity to the presence of auditory pathology.
All the data collected on the NST have shown that it is as easy to administer and score these as most of the traditional tests. Score sheets are available in both the International Phonetic Alphabet (IPA) and an easy dictionary pronunciation format. The NST consists of two 25-element lists in six randomizations. It is considered suitable for both children and adults.
The Nonsense Syllable Test© includes a) audio recording, and b) instructions and score form as printable pdf files. The nine-page instructions include background, scoring, and interpretation information. Normative data is included, but it is not age-specific because the test developer observed little or no age effects.
