Dr. Joseph P. Campbell is currently the Associate Group Leader of the Human Language Technology Group at MIT Lincoln Laboratory, where he directs the group's research in speech, speaker, language, and dialect recognition; word and topic spotting; speech and audio enhancement; speech coding; text processing; natural language processing; machine translation of speech and text; information retrieval; extraction of entities, links and events; multimedia recognition techniques, including both voice and face recognition for biometrics applications; and advanced analytics for analyzing social networks based on speech, text, video, and network communications and activities. Dr. Campbell specializes in research, development, evaluation, and transfer of speaker recognition technologies, evaluation and corpus design, and biometrics for government applications.
Dr. Campbell chairs the IEEE Jack S. Kilby Signal Processing Medal Committee and the International Speech Communication Association's Speaker and Language Characterization Special Interest Group (ISCA SpLC SIG). He is a member of the IEEE Medals Council, the International Speech Communication Association, Sigma Xi, the Boston Audio Society, and the Acoustical Society of America. Dr. Campbell was named a Fellow of the IEEE “for leadership in biometrics, speech systems, and government applications” in 2005.
Before joining Lincoln Laboratory as a Senior Staff member in 2001, Dr. Campbell served 22 years at the National Security Agency (NSA).
From 1991 to 1998, he was a senior scientist in NSA’s Biometric Technology research group and led voice verification research. From 1994 to 1998, Dr. Campbell chaired the Biometric Consortium, the US Government's focal point for research, development, test, evaluation, and application of biometric-based personal identification and verification technology. From 1998 to 2001, he led the Acoustics Section of NSA's Speech Research branch, conducting and coordinating research on and evaluation of speaker recognition, language identification, gender identification, and speech activity detection methods.
From 1979 to 1990, Dr. Campbell was a member of NSA's Narrowband Secure Voice Technology research group. He and his teammates developed the first DSP-chip software modem and 2400 bps LPC-10e, which enhanced the Federal Standard 1015 voice coder and improved US and NATO secure voice systems, including 300,000 Secure Telephone Units - Third Generation (STU-III). He was the Principal Investigator and led the US Government’s speech coding team in developing the 4800 bps CELP voice coder jointly with AT&T Bell Laboratories, which became Federal Standard 1016, provided improved voice quality in later STU-IIIs, and is the foundation of digital cellular and voice over the Internet telephony systems.
Dr. Campbell taught Speech Processing at The Johns Hopkins University (1991-2001) and was an Associate Editor of the IEEE Transactions on Speech and Audio Processing (1991-1999), an IEEE Signal Processing Society Distinguished Lecturer (2001-2002), a member of the IEEE Signal Processing Society’s Board of Governors (2002-2004), a coeditor of Digital Signal Processing journal (1998-2005), a member of the IEEE Information Forensics Security Technical Committee (2005-2009), the Vice President of Technical Activities of the IEEE Biometrics Council (2008-2011), and a member of the National Academy of Sciences' Whither Biometrics? Committee that produced the book Biometric Recognition: Challenges and Opportunities (2004-2010).
Dr. Campbell received the B.S. degree in electrical engineering from Rensselaer Polytechnic Institute in 1979, the M.S. degree in electrical engineering from The Johns Hopkins University in 1986, and the Ph.D. degree in electrical engineering from Oklahoma State University in 1992.
