    Exercise 3: Voice Activity Detection Tehtävä

    In this exercise, you will be implementing functions to extract simple speech features which are suitable for voice activity detection (VAD) and utilize them to train two simple VAD classifiers. The computed features are combined into a matrix that acts as the input data provider for our classifiers. The code for the classifier training and some features are already provided in the notebook, but you must experiment with different features and properties, and report your findings.
