My co-authors, Kris Predeck, Melina Sarian, & Georgia Zellou, and I are thrilled our paper ”Prosodic alignment toward emotionally expressive speech: Comparing human and Alexa model talkers” is now in press in Speech Communication. https://doi.org/10.1016/j.specom.2021.10.003

I’m thrilled that my paper with Georgia Zellou and Bruno Ferenc Segedin has been accepted to the Journal of Phonetics!

The paper examines acoustic-phonetic adjustments when people talk to a Siri vs. a naturally recorded human voice. We find prosodic differences (e.g., increased intensity, smaller f0 range in Siri-DS) as well as some targeted adjustments (vowel hyperarticulation in response to an error made by Siri). Across two experiments varying in error rate, we see differences in the way these register adaptions emerge.

Come learn about an interdisciplinary research project exploring how adults and kids talk to Amazon’s Alexa, compared to how they talk to a human. You’ll see an example of the experiment, meet the team, and get a behind-the-scenes look at the research process!
