As part of ETL or just basic understanding about the how the speech data is handled try this tool : https://github.com/wiseman/py-webrtcvad

It is a python wrapper for a library for voice activity detection. It acts as a starting point while working on speech recognition problems. Helped me understand and discover a lot of concepts related to audio signal and data when I was in your shoes.
