Programs for supporting the teaching of digital speech processing

This paper describes a set of about 60 MATLAB^®-based speech processing exercises designed to give students and instructors hands-on experience with digital speech processing algorithms and systems. This result is achieved by providing MATLAB code with a graphical user interface (GUI) for ease of use and understanding of the code. For each MATLAB exercise we provide a description of the code and GUI structure, an explanation of key technical aspects of the solution, a description of the organization of the Lite Graphical User Interface,¹ a scripted run of the software with an extensive set of speech files for processing, one or more results figures generated by the provided code, and a set of technical issues for further experimentation with the code. Our goal with these exercises was to provide a useful and unique set of speech processing tools for the instructor and a set of speech processing exercises (denoted as “Issues for Further Experimentation”) that students can use to develop their understanding of the relevant technical content of each speech processing exercise. This paper describes the resulting set of speech processing exercises and shows how they can be used to enhance the teaching of digital speech processing.
