Along with my co-authors, Kevin Lilley, Ellen Dossey, Cynthia Clopper, Laura Wagner and Georgia Zellou, we’re thrilled our paper has been accepted and is now in-press.

I’m pleased to serve as a panelist for the UC Davis Fellowship Career Panel for current Leaders for the Future and Business Development Fellows at UC Davis. I was previously a Leaders for the Future fellow, a joint program through GradStudies and the Mike and Renée Child Institute for Innovation and Entrepreneurship.

I had a great time at my guest lecture for UCLA linguistic anthropology graduate students, talking about how to launch research collaborations between academia and industry.

Talking to voice assistants: Cross-disciplinary and industry collaborations
Michelle Cohn & Georgia Zellou

Millions of people now talk to voice assistants (e.g., Siri, Alexa, Google Assistant) to complete daily tasks. These incidental interactions raise novel questions for our understanding of human communication and cognition. Do people differentiate how they talk to a human and device? Do people learn linguistic patterns from devices? Will talking to technology shape our language in the long term? In this talk, we present several of our cross-disciplinary and industry collaborations exploring speech interactions with voice technology (e.g., robots, socialbots, voice assistants).

Equitable automatic speech recognition (ASR): Collaboration with Google Research
Michelle Cohn, Zion Mengesha, Michal Lahav, Courtney Heldreth

While interactions with language technology can be helpful for a range of use cases (e.g., setting timers, reading labels aloud), work in responsible AI has shown that it does not work equally well for all individuals. In particular, speakers of underrepresented language varieties can face additional barriers. In this academic-industry collaboration, we investigate disparities in who language technology understands and make advancements for equitable automatic speech recognition (ASR).

I’ll be presenting at the UC Davis Cluster on Language Research on 11/6 from 1-2pm: “Investigating speech ‘biomarkers’ of cognitive impairment in technology-directed tasks”.

Zion Mengesha & I had a great time with our interview with Kat Setzer about our recent JASA-EL paper!

Across Acoustics: Why don’t speech recognition systems understand African American English?

African American English speakers’ pitch variation and rate adjustments for imagined technological and human addressees

I’m thrilled that along with my co-authors, Santiago Barreda, Katie Graf Estes, Zhou Yu, & Georgia Zellou, that our paper, “Children and adults produce distinct technology- and human-directed speech” has been accepted to Scientific Reports.

I’m thrilled to be one of two postdocs selected for the UC Davis Alzheimer’s Disease Research Center (ADRC) REC Scholar Program. I’ll be working with neuropsychologist, Dr. Alyssa Weakley, on acoustic analyses of speech by older adults with cognitive decline in her iCare system. Specifically, we will examine speech directed in Apple Watch commands, extending my work in technology-directed speech adaptations to a clinical context.
