Course Text

Digital Signal Processing

A Practical Guide for Engineers ande Scientists
Steven W. Smith

Newnes (2003), ISBN 13-978-0-7506-7444-7

Course Description

This class introduces students to the field of Audio Signal Processing. We focus on the area of speech recognition, and the ACORNS language revitalization project in particular. Subject areas include Fourier analysis, digital filters, standard audio formats, compression, and feature extraction. We will discuss the elements needed for the front end to an automatic speech recognition system.

Objectives

Upon completion of this course, students will have a working knowledge of Audio Processing techniques. As part of this course, students will make contributions to the ACORNS project. As a graduate course students will gain experience reading presenting relevant scholarly articles.

5 Complex Numbers

6 Fourier Transform

7 Digital Filters

8 Feature Extraction

9 Midterm Examination

11 Student Project Presentations

Course Grading

There will be three twenty minute student presentations. Each of these presentations will require students to read and present the contents of a published scholarly paper. Grades measure quality of the presentation and understanding of the subject matter. The presentations count for 20 percent of the final grade.

A quarter long project requires students to add to the ACORNS language acquisition software. The project is due during finals week. A final technical paper will describe the project in detail. Students will prepare a technical paper, power point slides, and keep a research journal during the quarter. The project grade bill measure the quality of the design specification, the final technical paper, the research journal, how well the software works, and the presentation. The project counts for 35 percent of the final grade.

Students will take a midterm examination in week nine of the quarter. This examination contributes thirty-five percent towards the final grade. Additional homework assignments and attendance will count for ten percent of the final grade. There will also be opportunities for extra credit.
