Android implements speech recognition code

Apple's iphone has Google's technology for voice recognition, and Android, Google's push, will naturally implant its core technology into Android and build it up with Google's cloud technology. So Google Voice recognition's implementation on Android became extremely easy.

Speech recognition, with the help of cloud technology to identify the user's voice input, including voice control technology, the following we will use the API provided by Google to achieve this function. The function point is: To recognize the user input speech through the user voice and print it on the list. The functional interface is as follows:

The user clicks the Speak button to display the interface:

After the user has finished speaking, will submit to the cloud search:

After the cloud search is complete, return the printed data:
