Voice Features for iOS development

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchOptions {

To create a voice configuration, AppID must be passed in and executed only once to

NSString *initstring = [[NSString alloc] initwithformat:@ "APPID=570F3DB3"];

Before all services are started, you need to ensure that createutility is executed

[Iflyspeechutility createutility:initstring];

return YES;

}

Create audio files using the Apple Native API framework. You need to add a header file to the Avfoundation framework, which will ask you to open this feature the first time the program is enabled. Use the Hkust API to use the online SDK only for free, and call the offline SDK to use only 3 iOS devices for 35 days. Offline purchase price is very expensive.
