Abstract

In this challenge, students will design and construct a system that will identify who is speaking. For this purpose students will use a free machine learning application. They will understand the concepts of building a model with samples, training it and testing results. Students will also learn the basics of the mathematics concerning sound.

This activity should be developed in groups of 3 learners. Teachers should help maintain the motivation of the learners particularly when they are struggling with the machine learning concepts and the use of the software application.
