Abstract [en]

Rudner et al (2008) showed that when compression release settings are manipulated in the hearing instruments of Swedish habitual users, the resulting mismatch between the phonological form of the input speech signal and representations stored in long-term memory leads to greater engagement of explicit cognitive processing under taxing listening conditions. The mismatch effect is manifest in significant correlations between performance on cognitive tests and aided-speech-recognition performance in modulated noise and/or with fast compression release settings. This effect is predicted by the ELU model (Ronnberg et al, 2008). In order to test whether the mismatch effect can be generalized across languages, we examined two sets of aided speech recognition data collected from a Danish population where two cognitive tests, reading span and letter monitoring, had been administered. A reanalysis of all three datasets, including 102 participants, demonstrated the mismatch effect. These findings suggest that the effect of phonological mismatch, as predicted by the ELU model (Ronnberg et al, this issue) and tapped by the reading span test, is a stable phenomenon across these two Scandinavian languages.
