Course Description:
A detailed treatment of theory and application of digital
speech processing. The course provides a fundamental knowledge of speech signals
and speech processing techniques. Topics include digital speech coding, speech
synthesis, speech recognition, and speaker verification.
Prerequisites: EE 7372, Digital Signal Processing
Text:
“Discrete-Time Signal Processing”, Thomas Quatieri
Prentice-Hall, 2002 (Required)
“Digital Processing of Speech Signals”, L. Rabiner & R. Schafer
Prentice-Hall, 1978 (Optional)

30% (Sat, May 1, 11:30-14:30)
Homework & Computer Projects:
•The homework will be more of the analytical type.
•Computer projects will require you to process signals and then view and listen to them.
The processing should be done using MATLAB, and the MATLAB files should accompany
the project, to be able to duplicate your results.
•Late homework: Solutions will be given on the lecture period after the homework is
collected. No homework will be accepted after solutions are posted.
•Late projects: The projects’ due date for distance education students will be one lecture
period after the in-class students. The grade will be reduced by 10% for every lecture
period you miss in turning it in. No projects will be accepted after the last day of classes.
Feedback:
After every lecture:
•What stood out as most important in today’s lecture?
•What are you confused about?
•Other comments / complaints / suggestions?
