Standardization of the Prosody in Use Battery (PUB): A speech prosody perception test in Danish
Publikation: Bidrag til tidsskrift › Tidsskriftartikel › Forskning › fagfællebedømt
Assessment of prosody perception may be useful in a number of clinical scenarios, including the rehabilitation of cochlear implant recipients. It is with this group in mind that we have derived and standardized a battery of tests that assess speech prosody perception in the Danish language. The prosodic contrasts included in the battery are vowel length, compounds and phrases, emotions, questions and statements, prominence and pronoun reference, all of which are commonly encountered in everyday communication. Lists of candidate stimuli were compiled and recorded by a representative speaker of Danish. All candidate stimuli were presented to normal hearing subjects (n=12) in both unprocessed and 8-channel noise vocoded conditions. Subjects performed closed-set identification and the results were used to derive the final stimulus set. We report the results of the six subtests, in which we observed a bias to compounds in the compound/phrase subtest, and to statements in question/statement subtest. The pronoun reference subtest assessed the ability of a listener to infer a referent from the stress status of a pronoun, and we found high accuracy rates on this task indicating that it is suitable for inclusion in the battery. We discuss the possible uses of the Prosody in Use Battery in cochlear implant mapping and device verification. We also consider the role of the results from the test battery in guiding clinicians to material suitable for aural rehabilitation.
