Hello, world. I'm a Computer Science Ph.D. candidate in ICSI's Speech Group. My research is in automatic speech recognition. I had a startup, Modista.com, providing visual search technology. That experience started well, but then ended with an ugly mess. Moving on...

Current projects

• Multilingual keyword spotting for the IARPA Babel program.

Past projects

• Speech recognition applications for the Parallel Computing Laboratory.
• Mandarin and Arabic ASR for the DARPA GALE program.
• VTLN for the English version of the SmartWeb recognizer.
• Searching broadcast news video for the TREC Video Retrieval Evaluation.
• Aligning video to imperfect transcripts of the Scottish Parliament (while at CSTR).
• Speech recognition of non-native speakers. (won an award)
• Graduate Student Instructor for CS188: Artificial Intelligence
