Capstone project on speech morphing: A highlight to undergraduate education on signal processing

Signal processing is a core discipline in electrical and computer engineering (ECE). The mathematical language adopted in the classroom and the laboratory support, usually limited to verification, pose the risk of hiding the enormous practical connotations of the discipline. This paper suggests to strengthen the bridge between theory and practice by means of selected capstone projects, designed according to constructivist principles. The project detailed in this paper tackles a large number of fundamental aspects of the discipline through a storyline that captivates the student during its execution.
