Izhak Shafran

Izhak Shafran is a speech researcher working on various topics in acoustic modeling and large vocabulary speech recognition.

Before joining Google, he was a faculty member for 8 years in the Center for Spoken Language Understanding (CSLU) at Oregon Health & Science University (OHSU) – part of what used to be the Oregon Graduate Institute (OGI). Before that, he was in the Speech Algorithms Department at AT&T Labs - Research from 2001–2003 and a research faculty at the Center for Language and Speech Processing (CLSP) at the Johns Hopkins University from 2003-2006. He received his Ph.D. in the Department of Electrical Engineering at the University of Washington Seattle in 2001.
