I'm a postdoctoral researcher trying to figure out how human voices work.
The big questions I'm interested in are:
My research attempts to address these questions by looking at the acoustics of how people change their voices in different situations, and how this is related to brain activation, as well as more subjective things like feelings of agency and affiliation.
Talking humans in a social world: communicative modulation of fluent and dysfluent speech production.
For most of us, our voices are one of the major ways in which we navigate daily life— it’s how we communicate, and we judge other people based on how they speak to us. For some people, having a chat with the barista is a perk of getting their morning coffee. For others, especially those with speech production difficulties such as stuttering, it might be a source of frustration. Either way, all over the world, speaking to other humans is a core part of human interaction. Yet when scientists try to understand how the brain helps or hinders us from talking, their experiments often involve people talking on their own in a quiet room, devoid of distraction.
I want to understand how the brain produces everyday conversational interactions in neurotypical talkers and people who stutter. I also want to understand why people stutter, and how having a stutter affects everyday interactions and employment outcomes. Work on stuttering is mainly based on data from Western populations so I’ll be expanding that research by working with people who live in Mysore, India, whose native language has a different structure to English. And I will use fNIRS, a technique that can track brain activation in two people at once while they talk to each other, to look at the brain basis of speech in real-world contexts.
I hope this work will help us understand how speech production works in the real world, for people who are fluent and people who aren’t.
