Dr. Joseph P. Campbell is the leader of MIT Lincoln Laboratory's Human Language Technology (HLT) Group. The group is engaged in a wide range of efforts focusing on speech, text, image, multimedia, and language processing. The group’s speech and language processing research and development (R&D) efforts include automatic speech recognition, speaker recognition, language and dialect identification, keyword search, topic analysis, speech and audio signal enhancement, and machine translation. The HLT Group's newest R&D efforts include domain adaptation for HLTs; cross-language information retrieval systems; cyber and transaction analysis; entity and relationship extraction; cross-media recognition; recommender systems; language-learning technologies; and analysis of social networks based on information content extraction from speech, text, and video combined with network communications and activities. In each of the group's R&D areas, emphasis is placed on realistic data and experimental evaluation of techniques. On a global scale, the HLT Group leads research in several speech, text, and multimedia analytics domains, with a long-standing and extensive publication record and history of international honors for staff.

Dr. Campbell is a leader in the aforementioned areas, and he specializes in transferring these technologies for government applications and their evaluation. He has authored or coauthored more than 100 refereed publications that have been referenced by more than 5,000 citations; his invited tutorial on speaker recognition, published in the Proceedings of the IEEE, has received more than 1,750 citations. In addition, he holds one U.S. patent and led two U.S. Federal Standards, one Federal Information Processing Standard, and one NATO Standardization Agreement.

Dr. Campbell is chair of the Speaker Recognition Subcommittee of the NIST Organization of Scientific Area Committees, co-chair of the Speaker and Language Characterization Special Interest Group of the International Speech Communication Association, co-chair of the MIT Lincoln Laboratory Professional Societies Committee, vice chair of the IEEE Awards Board's Awards Planning and Policy Committee, and a member of the Advisory Board for the Human Language Technology Center of Excellence at Johns Hopkins University. He is a member of the IEEE Signal Processing and Communications Societies, 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.

He joined Lincoln Laboratory in 2001 as a senior staff member after serving 22 years at the National Security Agency (NSA).

From 1991 to 1998, Dr. Campbell was a senior scientist in the National Security Agency (NSA) Biometric Technology Research Group and led voice verification research. From 1994 to 1998, he chaired the Biometric Consortium, the U.S. 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 1991 to 2001, Dr. Campbell taught speech processing at Johns Hopkins University.

From 1979 to 1990, Dr. Campbell was a member of the 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 U.S. and NATO secure voice systems, including 300,000 Secure Telephone Units–Third Generation (STU-III). He was the principal investigator and led the U.S. 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 was a member of the IEEE Speech Technical Committee (1989–1992), 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 co-editor of Digital Signal Processing journal (1998–2005), a member of the IEEE Information Forensics Security Technical Committee (2005–2009), a member of the IEEE Signal Processing Society's Fellow Reference Committee (2007–2010), the vice president for technical activities of the IEEE Biometrics Council (2008–2011), vice chair of the Acoustical Society of America's Forensic Acoustics Subcommittee (2011–2013), chair of the IEEE Biometrics Council's Technical Committee (2011–2013), chair of the IEEE Jack S. Kilby Signal Processing Medal Committee (2012–2013), member of the IEEE Medals Council (2012–2013), and a member of the National Research Council's National Academy of Sciences' Whither Biometrics? Committee that produced the book Biometric Recognition: Challenges and Opportunities (2004–2010).

Dr. Campbell earned bachelor's, master's, and doctoral degrees in electrical engineering from Rensselaer Polytechnic Institute, Johns Hopkins University, and Oklahoma State University, respectively. He received Oklahoma State University's Graduate Research Award for best dissertation across all the colleges, "Features and Measures for Speaker Recognition."
