In this exercise, we implement functions to extract basic speech features suitable
for voice activity detection (VAD) and utilize them to train two simple VAD
classifiers. These features include: Zero-crossing rate (ZCR), energy, and one-lag auto-correlation. The features are then computed from a test utterance, and
combined into a matrix that acts as the input data provider for our classifiers.
The addition of delta and delta-delta parameters is also implemented. The code
for the classifier training is provided, but you must experiment with different
features and properties and report your findings.
