To understand speech, we have to figure out how the acoustic signal relates to the speech sounds we know (a task made difficult by the considerable variability in how individuals talk), find the word breaks in the speech stream (which aren’t always easy to identify), and retrieve the correct words from our mental dictionaries (and not, for instance, a similar-sounding one). It should be a daunting task, and yet listeners seem to perform the task optimally.

As a graduate researcher, I am particularly interested in the mental computations that underlie the process of spoken word recognition as well as how these computations are achieved in the brain. How are we able to achieve such good perception, especially given the limited amount of cognitive resources we have at our disposal? How might we rely on other sources of information (sentence context, our knowledge of we are talking to, etc.) to make the word recognition process easier?
