Abstract: An attractive Android-based mobile educational platform for teaching speech signal processing is presented in this paper.The proposed platform has the advantages of high portability,strong affordability,adequate interactivity,and easy adoptability with high-hierarchy graphic user interface and extensive hands-on experiences.The experimental results show that this platform can significantly cultivate students’ learning interest,improve their practical ability,and consolidate theoretical concepts.The platform is also appropriate for the signal-processing related courses,which can provide new ideas and means for the construction of modern teaching reform.
