Mary E. Beckman, Principal Investigator

Mary Beckman's current research focuses on phonological development. This the process by which babies learn to pick out words and other structures in the speech addressed to them and to match these up to the sounds patterns they themselves produce, and then gradually grow a vocabulary and a "grammar" for combining sounds and words into completely novel utterances. It also involves learning to listen like a native speaker as well as learning to sound like someone who belongs in the ambient speech community.

Eric Fosler-Lussier, Co-Principal Investigator

Eric Fosler-Lussier is the director of the Speech and Language Technologies Laboratory in the OSU Department of Computer Science and Engineering. The overall goal of the lab's research is to find meaningful ways to integrate acoustic, phonetic, lexical, and other linguistic insights into the speech recognition process through a combination of statistical modeling and data/error analysis. He was a co-PI on the NSF grant that funded the Math-to-Mouth project from 2008-2011 and he remains involved with OSU learningtotalk.org personnel.

Andrew Plummer, Post-Doctoral Researcher

Andrew Plummer's research focuses on the conceptual foundations and computational modeling of the earliest stages of phonological acquistion during infancy. He is currently a postdoctoral researcher in Eric Fosler-Lussier lab at OSU, working on the speechkitchen project.

Bridget Smith, Post-Doctoral Researcher

Bridget Smith is currently extending her dissertation research, which examined changes in production and perception of consonant clusters wrought in laboratory sound change experiments, to focus on the intersection of phonological acquisition and literacy, especially changes in phonological organization that may occur as a result of learning to read, and the role of this phonological restructuring on production, and its impact on sound changes occurring in the speech community.

Jennifer Zhang, Graduate Student

Jennifer Zhang earned an undergraduate degree in Lingusitics at the Ohio State University, where she participated in research on fricative acquisition with Ya-ting Shih and Jeff Kallay, before teaching for a year in Chile and Nicaragua.  She is interested in phonetics and language acquisition. She would like to do more research to improve acoustic measures of fricative acquisition and also to investigate how 3rd language acquisition affects 2nd language acquisition and how these effects can be measured acoustically.
