Matlab exercises in support of teaching digital speech processing

This paper describes a set of 58 Matlab^®-based speech processing exercises designed to give students and instructors hands-on experience with digital speech processing basics, fundamentals, representations, algorithms and applications. This result is achieved by providing working Matlab code using a LITE graphical user interface (GUI) for ease of use and understanding of the code. For each Matlab exercise we provide a brief 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, a scripted run of the software with an extensive set of speech files for processing, some results figures generated by the provided code, and a set of technical issues for further experimentation with the code. Our goal with these exercises is to provide a set of speech processing tools for the instructor and an extended set of speech processing exercises (denoted as “Issues for Further Experimentation”) that students can use to develop their understanding of the technical content of each speech processing exercise. This paper describes the resulting set of exercises and shows how they can be used to enhance the teaching and learning of digital speech processing.
