Speech segmentation for speaker recognition
I'm going to answer my own question, for those who are looking for the same information as I was. Adaptive Thresholding is the most common way to segment audio, and it gives you the most bang for the buck. While there are more accurate methods out there for segmenting, adaptive thresholding is fast and very accurate, and uses simple features such as zero-crossings, energy, and entropy. I'm going to have to look into this more myself but this should be enough to get started.
