I am a Ph.D student in Computational Linguistics at Indiana University, researching speaker variability & categorization, as well as syntactic and phonological acquisition & parsing.

Speaker Variability

I am interested in speaker variability as a complete process from the speech signal to the syntactic representation. How are speakers different from each other and at what 'level' do these differences form linguistic groups (accent/dialect)? Can these differences be measured effectively? How can these differences be used for speaker identification, group classification, and improving speech recognition systems?

Linguistic Acquisition

How, with all of these variability, can a child learn a language that is more or less the same as that spoken in their surrounding environment? What can computational models of linguistic acquisition teach us about child language acquisition, and what can naturalistic learning teach us about computational induction and parsing?

Cognitive Architecture

There are no computer systems that can beat the human brain at overall language performance. What can we learn from studies of the mind that could increase computational language performance? What can a computational model prove or disprove about the way the mind works?

I study some Central Asian languages. I posted some flashcards, pronunciation and grammar references for Arabic, Turkmen, and Uzbek.
