This question evaluates understanding of audio data preprocessing and end-to-end model training, assessing competencies in feature representation choices, normalization, segmentation, augmentation, and pipeline orchestration within machine learning for audio.

Suppose you are building an audio model for a voice assistant. Compare common audio data preprocessing approaches and explain their trade-offs. For example, discuss choices such as raw waveform input versus engineered features, normalization, segmentation, and data augmentation. Then describe the concrete end-to-end steps you would follow to train the model, from data preparation through evaluation.
