摘要

Audio signals are a different type of data than the more commonly seen types, such as text, numbers and images. Thus, numerical feature extraction for audio data is different and follows processes that try to replicate how human ears perceive sound. Audio and speech processing has a massive amount of research and methods available in MATLAB. Given the popularity of Python in the field of Machine Learning, feature extraction and audio classification model building in Python will be discussed. This talk will cover details about Audio signals, feature types, feature extraction using Python, open-source tools, followed by practical examples of training Machine Learning models using Audio data.
