Academic research

My my academic research focussed on two general themes:
The first theme concerned speech sound processing and its neural underpinnings. Although we are mostly unaware of this, perceiving speech, is a tremendously complex task, partly because different speakers produce speech sounds in very different ways. One of the questions I have been investigating is how listeners use context and learning to resolve such variability. This applies to a range of speech cues such as the perception of formants, speech sound durations and (lexical-) tone in Cantonese. For this line of research I have relied on methods such as behavioral tasks, ECoG, eye-tracking and EEG.

The normalization of speech cues

The role of learning in interpreting speech cues

The development on a nonnative phonology in school-age children



The second theme focussed on the distribution of load between perception and production in turn-taking. In typical turn-taking situations, listeners and speakers alternate very quickly. In fact, the gaps between the turns are often so short, that participants must, sometimes, be listening and planning their speech at the same time. This raises the question how people manage to these things at once, and whether that affects their speaking and listening quality. For this line of research I have relied on methods such as behavioral tasks, eye-tracking and a newly developed dual-task (based on tapping).
