Software/program for audio analysis

I am doing my final year research on developing an automated scoring system of presentation skills. I want the system to be able to determine whether the presentation is good based on the pitch, speaking rate of the presentation. I have thought of Praat(audio analysis software), but I don’t know how can I link it to my code. Also, I have tried to use Python library for audio analysis but I couldn’t find a suitable one.What should I do?
