  • profile


I am a senior researcher at Idiap Research Institute in Martigny, Switzerland, external teacher at EPFL and also an associate professor at Brno University of Technology (BUT), Faculty of Information Technology (FIT). My research interests include audio and speech processing (especially speech and speaker recognition), and its applications for various tasks (i.e. embedded platforms, robotics, forensic voice comparison).

Part of my scientific work was also done at Oregon Graduate Institute, USA (2000-2001) and at Ecole Superieure d’Ingenieurs en Electrotechnique et Electronique, France (1999).

Dr. Petr Motlicek received the M.Sc. degree in electrical engineering and the Ph.D. degree in computer science from Brno University of Technology (BUT), Czech Republic, in 1999 and 2003, respectively. In 2000, he conducted research on very low bit­-rate speech coding at Ecole Superieure d’Igenieurs en Electrotechnique et Electronique (ESIEE), Paris, France. From 2001 to 2002, he was a research intern at Oregon Graduate Institute (OGI), Portland, U.S., collaborating with Prof. Hermansky in the area of distributed speech recognition. Dr. Motlicek currently holds a position of assistant professor at Faculty of Information Technology, BUT. He is aligned with Department of Computer Graphics and Multimedia led by Prof. Cernocky.

From 2005, Dr. Motlicek has been a Postdoc Researcher at Idiap Research Institute, Martigny, Switzerland, working in the area of low bit-rate speech coding. In 2018, he received a position of senior research scientist at Idiap, focusing especially on R&D activities in the domain of automatic multilingual speech recognition, speaker recognition as well as spoken language understanding. He is currently specialising on security related research (EU FCT R&D), and also in EU research for automation in air-traffic management.

From 2012, Dr. Motlicek is an external lecturer at Ecole Polytechnique Federale, Lausanne, Switzerland, teaching speech processing related courses in Ms.C. and Ph.D. programmes.

In summer 2010, Dr. Motlicek participated in the ASR workshop coordinated by Dr. Daniel Povey resulting in a new speech processing framework called KALDI.

From 2000, Dr. Motlicek has been a member of IEEE (senior member from 2008) and ISCA.

Dr. Motlicek has been the project coordinator of:

  • ROXANNE EC H2020 security project,

  • ATCO2 EC H2020 CleanSky project.

He has been participating as researcher or principal investigator in several other European projects such as TA2 and TA2-EEU, DBOX, DIRAC, AMI and AMIDA, DBOX, SiiP, Malorca, MuMMER, Haawaii, CRiTERIA. Dr. Motlicek participated in recently ended IARPA project called SARAL, funded by the U.S. government.

Dr. Motlicek has collaborated with industries such as Qualcomm and Samsung on patent applications.
