Iflytek speech recognition

Register your account with the Iflytek open platform, create an app and download the SDK, unzip the SDK package, and drag the framework into the project, such as

Then you'll import the class library: specifically,

Create a project, we are divided into two parts, the first part is in the Fristviewcontroller, the realization of speech recognition function, the second part is in the Secondviewcontroller, the realization of text conversion to speech

First Import the header file in APPDELEGATE.M

1 // Import Header File 2 #import <iflyMSC/iflyMSC.h>

Then sign in to the APPDELEGATE.M. Iflytek Voice Platform
