To work with microphones we will have to install PyAudio package in python.
Microphone class
To record audio using the microphone
we will have a microphone class.

We will make a program using the speech recognition python to execute the
following:
* Converting speech to text using speech recognition
* Using the text to open a URL using web browser
* Searching a query using speech inside the URL
