Android realizes speech recognition code _android

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.
