This laboratory is used to support undergraduate and graduate courses in Digital Speech Processing (when offered) and for research.

The research work conducted in this laboratory supports a Ph.D. student and consists of investigations related to speech intelligibility, particularly by hearing-impaired listeners. This work can be divided into three distinct areas.


  • ECE 477 - Digital Processing of Speech Signals (when offered)
  • ECE 601 - Master's Graduate Thesis
  • ECE 646 - Digital Speech Processing (when offered)
  • ECE 701 - Doctoral Dissertation Research
