About us

  • Digital signal processing (DSP) refers to a broad area of research that concerns all kinds of problems in acquiring, analyzing, interpreting and manipulating digitized signals or data. It is the foundation of telecommunication and Internet, and has enabled innumerable innovations in the areas of multimedia, security, health care, etc. At the DSP & Speech Technology Laboratory (DSP-STL), our current research is focused on: (1) signal processing for communication; (2) speech and audio processing; (3) language and neuroscience.

  • DSP-STL is a venue to nurture young researchers, to foster cutting-edge research, and to transfer knowledge into technological practice. It is an open and lively environment featured by cross-disciplinary study, research exchange opportunities and industrial collaboration. We welcome PhD applicants, undergraduate research interns and visiting researchers
