Speech is extremely variable along many different dimensions. One source of variability listeners often encounter is accented speech, in which phonological units can systematically differ from the listener's native categories. This dissertation presents five experiments testing how listeners adapt to accent-based phonological variability,…

Purpose: Speech recognition percent correct scores fail to capture the effort of mentally repairing the perception of speech that was initially misheard. This study measured the effort of listening to stimuli specifically designed to elicit mental repair in adults who use cochlear implants (CIs). Method: CI listeners heard and repeated sentences…

The aims of this particular study are twofold: (1) to analyze and classify the errors made by Swedish pupils in an oral English test in an effort to establish error patterns; and (2) to describe how the twelve most frequent errors in…

Fifteen Chileans were asked to tell stories in English, and several panels of native…
