About Me

I was born in Most, Czech Republic and received the M.S. degree in electrical engineering and Ph.D. degree in electrical engineering and information technology from the Department of Electrical Engineering, Czech Technical University in Prague, in 2003 and 2008, respectively. In August 2007, I joined the Center for Robust Speech Systems (CRSS), Eric Jonsson School of Engineering and Computer Science, University of Texas at Dallas, as a Research Associate and in 2012 as an Assistant Research Professor. Since August 2015, I have been an Assistant Professor in the Electrical Engineering Department at the University of Wisconsin-Platteville and an Adjunct Research Scientist at CRSS, UT-Dallas. At UW-Platteville, I established the Pioneer Speech Signal Processing Laboratory (PSSPL) whose mission is to engage undergraduate students in research on speech technologies and connect them with graduate institutions and industry. I have authored/co-authored over 60 journal and conference papers and am currently co-writing a book, under contract, on speech variability induced by stress, emotions, and Lombard effect, and their impact on speech engines. My research interests span the areas of digital signal processing, acoustic signal modeling, and machine learning, with the focus on automatic speech and speaker recognition, language and dialect identification, stress, emotion and cognitive load classification, automatic assessment of physiological traits from speech signals, robustness to environmental and speaker-induced variability, and language acquisition in infants. I served on the Technical Committee of the Listening Talker (LISTA) Workshop on Natural and Synthetic Modification of Speech in Response to Listening Conditions (Edinburgh, UK, 2012) and on the Editorial Advisory Board of the book 'Technologies for Inclusive Education: Beyond Traditional Integration Approaches' (Eds. D. Griol, Z. Callejas, R. L. Cozar) IGI Global, 2012. I served as an external reviewer for the Ministry of Business, Innovation, and Employment of New Zealand (MBIE) and as an independent expert in two patent infringement cases in the field of automatic speech and speaker recognition, two patent validity reexamination cases in the field of automatic speech recognition, and a voice forensics case.

Research Interests

  • Acoustic modeling for varying environments
  • Limited resource tasks

Speech Analysis/Modeling/Assessment

  • Stress, cognitive load and emotions in human-human and human-machine interactions
  • Phonotactic modeling for language and dialect identification
  • Language acquisition in infants
  • Physiological traits in speech signals

Music Signal Processing

  • High-precision pitch tracking for real-time acoustic signal transcription and audio-to-MIDI conversion
