Development of an Australian behavioural method for assessing listening task difficulty at high speech intelligibility levels.

Objective: To develop and validate an Australian version of a behavioural test for assessing listening task difficulty at high speech intelligibility levels.

Design: In the SWIR-Aus test, listeners perform two tasks: identify the last word of each of seven sentences in a list and recall the identified words after each list. First, the test material was developed by creating seven-sentence lists with similar final-word features.
