word recognition score
Percentage of single-syllable words correctly repeated at a comfortable listening level, assessing speech clarity.
Full Definition
Word recognition score (WRS), formerly called speech discrimination score, measures the percentage of phonetically balanced single-syllable words correctly repeated when presented at the patient's most comfortable loudness level or a fixed intensity above their speech reception threshold. This test evaluates the clarity aspect of hearing and the auditory system's ability to process speech information. Poor word recognition scores may indicate retrocochlear pathology or suggest limited benefit from conventional amplification.
Usage
Usage note: Modern term is 'word recognition score' rather than the older 'speech discrimination score'. Express as percentage.
