Research

Founded The Center for Robust Speech Systems (CRSS) at the Univ. of Texas at Dallas in 2005 which is focoused on interdisciplinary research in speech processing and human computer interaction.Oversees the CRSS - Speech & Speaker Modeling Group. Originally founded the Robust Speech Processing Laboratory in 1988 at Duke University, which became the Robust Speech Processing Group at CSLR in 1999, Univ. of Colorado, now the Center for Robust Speech Systems (CRSS-UTD). Research has focused on interdisciplinary areas in robust speech processing and recognition, digital signal processing, speech and speaker analysis, human-computer interfaces/interaction, speech enhancement and processing in noise, and voice communications. Specific research accomplishments include analysis and modeling of speech for voice and telecommunications applications, robustness issues for speech recognition in adverse conditions, speech enhancement, spoken document retrieval, in-vehicle voice navigation dialog systems, and voice modeling in noise, stress, accent, and Lombard effect. Has also had extensive collaborations on research in telemedicine, resulting in numerous contributions in medical speech processing involving detection and quality assessment of speech under stress and pathology. At Univ. of Colorado, he co-founded the Center for Spoken Language Research, which is now CRSS at UTD and has focused on rich transcription for spoken document retrieval, hands-free robust recognition for in-vehicle voice navigation, advanced human-computer interaction, speaker/speech analysis for stress, accent/dialect analysis and modeling, and Lombard effect. While at Duke University Dept. Electrical Engineering, established collaborative research program with Duke Medical Center (Dept. of Pediatrics, Speech & Language Pathology), Johns Hopkins Medical Center, Scottish Rite Children's Medical Center. At University of Colorado, he has established collaborations with Walter Reed Army Institute of Research, NATO ITO/RSG.10, Nagoya University (Japan), Aalborg University (Denmark), Helsinki Univ. of Technology (Finland), Vincent Voice Library (Michigan State Univ.), Collaborative Digitization Program (Colorado), and Tufts University Digital Library. At University of Texas-Dallas, he established/continued collaborations with Nagoya University (Japan), Koc Univ./Sabanci Univ. (Turkey), Aalborg University (Denmark), Collaborative Digitization Program (Colorado), SRI , IBM TJ Watson Research Center, Texas Instruments, University of Zaragoza (Spain), Universidad Autónoma de Madrid, (Spain).

The majority of research in the field of speech processing for telecommunications focuses on formulating algorithms for ideal laboratory conditions. As many have shown, the resulting algorithms do not perform well in real or actual voice communication environments. The systems we develop focus on addressing issues relating to robustness issues of speech applications in telecommunications. Some of these issues relate to speech produced in noise, high stress, accent, or Lombard effect. The future of Multimedia human/machine interfaces will depend on system approaches which are capable of addressing the wide range of adverse conditions in which speech may be produced for applications in speech recognition, communications, language identification, speaker recognition, and other telecommunication applications.

Formulated the first class of constrained iterative speech enhancement algorithms based on novel properties of speech production and auditory processing. Established the only working framework based on Source Generator Theory for characterizing speech production under stress, resulting in novel stress equalization and noise suppression algorithms for robust speech recognition in noise, stress, and Lombard effect. NSF funded collaborative research program (with Michigan State Univ.: Electrical Engineering [Prof. Deller] and Vincent Voice Library [Prof. Seadle]) resulted in the development of SpeechFind [http://Speechfind.utdallas.edu] --- spoken document retrieval system which spans audio from the past 110 years. Research also in the area of smart vehicle systems for improved human-vehicle interaction. Includes DARPA sponsored CU-Move and NEDO/UTD supported UTDrive [http://www.utd.edu/research/utdrive/Home.htm], and international collaboration with Japan, Turkey, Singapore, Italy.

The Robust Speech Processing Laboratory was established in 1988, and continued on as the Robust Speech Processing Group at CSLR, and now CRSS at UD-Dallas.. Has served as Principal Investigator on more than $12M in external funded research from such sources as NSF, Whitaker Foundation, DoD/DARPA, U.S. Air Force, U.S. Army, U.S. Navy, TSWG, IBM (T.J. Watson Research Center, Voice & Telephony; MWave DSP Development), AT&T Bell Labs (Government Systems, Wireless), Motorola, HRL, SpeechWorks, Visteon/Ford, Voice Signal Technologies, Mishubishi, Toyota CR&D, Working Solutions, Texas Instruments, and others. Author of more than 300 journal and conference papers and 8 textbooks in the area of speech and signal processing, and is coauthor of the textbook Discrete-Time Processing of Speech Signals, IEEE Press, 2000, DSP for In-Vehicle and Mobile Systems, Springer, 2004, and the research monograph Automatic Recognition of Speech in Stressful Environments, published by DoD, 1991, and was lead author of the monograph "The Impact of Speech Under "Stress" on Military Speech Technology," NATO Research and Technology Organization, RTO-TR-10 AC/323(IST)TP/5 (ISBN 92-837-1027-4).

Speech Technology Researcher Recognized by Peers
UT Dallas News Center
Dr. John H.L. Hansen of UT Dallas has been named a fellow of the International Speech Communication Association, which recognized him for “significant contributions to the field of speech communication science and technology.” 
 
It is one of the organization’s highest honors.
 
Hansen’s research interests span the areas of digital speech processing, speaker trait assessment, speech and speaker recognition, and human-computer interaction. But perhaps most important is the very practical twist he’s brought to his work.

Dr. John Hansen Named Head of EE Department At Jonsson School of Engineering & Computer Science
UT Dallas News Center
Dr. John H. L. Hansen, chairman of the Department of Speech, Language and Hearing Sciences at the University of Colorado at Boulder, has been named head of the Electrical Engineering Department in the Erik Jonsson School of Engineering and Computer Science at The University of Texas at Dallas (UTD). He will assume his new responsibilities in the fall semester.
 
In announcing the appointment, Jonsson School Dean Dr. Bob Helms described Hansen as a “world-class scholar, educator, leader and administrator” who would help Jonsson “accelerate its move toward attaining tier one status as one of the top 50 engineering schools in the United States.”
