DISCRETE-TIME SPEECH PROCESSING

Prior exposition to a course on partial differential equations on the top of understanding of signals and systems, digital signal processing, stochastic signal processing, pattern recognition as well as pre-existing computer programming skills facilitate the grasping of concepts by the students as well as their successful enrollment in the course.

Sides and MATLAB demos.

a1) Lecture attendance and active participation in them is compulsory. Absence from 30 the total educational activities is tolerated at most. Failure to comply with this requirement implies failure in the course automatically. a2) Homework is assigned to students, including survey writing and computer-based project implementation. The surveys deal with the various stages of the discrete-time speech processing, speech and speaker recognition, and statistical language engineering. The computer-based projects aim at modeling speech production by humans, speech segmentation, short-time speech processing, linear prediction analysis, homomorphic speech processing, dynamic time warping, and so on. Students are requested to develop demo applications in MATLAB or python. One survey and one related computer-based project is assigned to each student. Homework assignment is posted to the course web page at http://pileas.csd.auth.gr. a3) Hourly mid-term and final progress exams are organized in the course. During these exams, the students are requested to provide short answers in 10-15 questions covering the topics taught in the course. The mid-term exam is scheduled for the 8th week and the final progress exam will take place during the period of exams. The final grade results by 10% from the survey assessment, 50% from the computer-project assessment (including project presentation), and 40% from paper grading in the mid-term and final progress exams. The students pass the course, if their total grade is greater than on equal to five (5). Details on the grading procedure are announced in the course web page, which supersede any prior arrangement.
