Python calls Baidu Voice (speech recognition-bucket landlord voice card)

I. Overview

This article briefly introduces the basic use of the voice recognition of Baidu (in fact, when the landlord wants to get a card player and no money, grab a bag of what is not, had to make speech recognition)

Second, create the application
