Using the SpeechRecognition library

To save typing speech_recognition every time, we'll import it as sr.

We'll also setup an instance of the Recognizer class to use later.

The energy_threshold is a number between 0 and 4000 for how much the Recognizer class should listen to an audio file.

energy_threshold will dynamically adjust whilst the recognizer class listens to audio.
