• Resumen

  • This paper introduces a software developed using MATLAB to help undergraduates gain a deeper understanding of thetheoretical concepts of digital signal processing they learn in the class. The tool, ESO-Lab, demonstrates importanttheoretical concepts, such as filter model, windowing, signal modification, poles and zeros, and post-processing filtering, asthey apply to real cases of pathological speech improvement. The tool was used by the students to conduct severallaboratory exercises. Its impact on students’ satisfaction was assessed through a survey in which 16 students participated.The approach seems to lead to satisfactory results in terms of learning and student motivation.
