Recognizer class basically has instances which are used to recognize speech. Each instance has seven
methods to recognize speech from any audio source using various APIs.
recognize_bing( )
recognize_sphinx( )
recognize_wit( )
recognize_ibm( )
recognize_houndify( )
recognize_google_cloud( )
recognize_google( )

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.

Installing pyaudio works the same way as any other module in python.
$ pip install PyAudio

15. www.edureka.co/python

16. www.edureka.co/python
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
