I am a PhD candidate at the Center for Spoken Language Understanding
at Oregon Health & Science University
(OHSU), studying under the direction
of Alexander Kain. I am
currently writting my dissertation and plan finishing mid-2015.
My long-term research goals are to develop novel methods in continuous
speech modeling for English. Specifically my work entails constructing
data-derived coarticulation models of continuous speech to allow
speaker-specific speech synthesis, making conversational speech more
intelligible, characterizing dysarthria, increasing accuracy in
automatic speech recognition, and increasing our understanding of
human speech production. Future work may involve applying this
approach to Japanese.
In addition to speech related research, I also continue with
NLP-related research and development. This work has focused on
language identification, encoding detection, text classification and
other tasks that are usually associated with content-filtering with a
focus on building production-quality systems. In general, AI
(artificial intelligence; now mostly called machine learning) has been
a passion for me since my early teens.
