| dc.description.abstract | Speech testing is an important part of the audiological test battery as it able to provide an index of a listener’s hearing ability beyond what can be revealed with conventional puretone audiometry. Matrix Sentence Tests (MSTs) assess speech understanding in noise and are thought to better approximate the hearing deficits a person might experience in ‘real world’ situations. The dialectical differences of New Zealand English necessitated the creation of the University of Canterbury Auditory-Visual Matrix Sentence Test (UCAMST; O’Beirne, Trouson, McClelland, Jamaluddin, & Maclagan, 2015; Trounson, 2012), which was adapted from the British English MST to accommodate the unique phonology of New Zealand English and ensure the validity of the measure. As part of a series of studies aimed at progressing the UCAMST towards clinical use, this project sought to continue the process of examining the equivalency across the lists and conditions available for use each of the presentation modes included in the UCAMST. Evaluation with 61 normal hearing participants revealed the sentence lists designed for use in the babble noise condition to be equivalent, however sentences designed for presentation in quiet were significantly different. An additional assessment of 20 normal hearing participants found comparability between numerous condition pairs in terms of the accuracy by which a listener’s speech reception threshold is estimated. The data from these participants was also used to cross-validate the UCAMST with two speech audiometry tests routinely carried out in NZ, demonstrating a significant relationship between the speech recognition thresholds of the UCAMST and the meaningful CVC (revised AB) word recognition test. The findings of this study provide evidence for the interchangeable use of sentence lists and conditions in the UCAMST and the potential capacity of the UCAMST to replace the meaningful CVC (revised AB) word recognition test in clinical practice. | en |
