Development of micro-credit public number voice message recognition PHP code _php instance

This example for you to share the PHP micro-letter speech message Recognition code for your reference, the specific contents are as follows

1. Open speech recognition (closed by default)

2. Speech recognition

Note that after the speech recognition is opened, the micro-letter adds a recognition field to the tweets message XML packet when the user sends the voice to the public number (note: Because of the client cache, the developer turns on or off the speech recognition function, it immediately takes effect for new followers, It takes 24 hours to take effect on the user who has been concerned. Developers can focus on this account again for testing). The speech XML packets that turn on speech recognition are as follows:
