OBJECTIVES: The intelligibility-based Repeat-Recall Test (i-RRT) seeks to compare secondary speech-in-noise (SiN) test outcomes, such as listening effort, against normative references measured at equal levels of SiN intelligibility. The present study evaluates the reliability, sensitivity, and accuracy of the easy speech reception threshold ("ezSRT") test, the first part of the i-RRT, a Bayesian-guided adaptive SiN...

Discussion
Signed responses from readers of the wire.
The i-RRT offers a potentially more efficient Bayesian method for estimating multiple speech-in-noise thresholds and listening effort in a single test session; audiologists should monitor validation studies before integrating it into routine clinical protocols.
A validated, efficient multi-threshold speech test could streamline clinical assessment of speech-in-noise performance and listening effort, areas that standard audiograms consistently miss.
- 01Introduces the i-RRT (Intelligibility-Based Repeat-Recall Test), a new Bayesian-guided speech assessment tool published in Ear & Hearing.
- 02Designed to estimate multiple speech reception thresholds (the quietest level at which speech is understood) in a single adaptive procedure.
- 03Also captures secondary outcomes such as listening effort compared against normative references.
- 04Bayesian guidance allows the test to adapt in real time, potentially reducing test time versus traditional fixed-level methods.
- 05This is a methods/development paper (Part I); clinical validation across diverse populations is still needed.
The i-RRT can estimate multiple speech reception thresholds using a Bayesian-guided adaptive procedure.
