UI Advanced Iflytek (1) Voice dictation (voice translated into text)

First, the Hkust flying open platform:

http://www.xfyun.cn/

Register, log in and create a new app.

Because this project only implements voice dictation, check the Voice Dictation single SDK in the SDK Download Center.

Development platform Select iOS, app Select the app you want to implement voice dictation, then click the "Download SDK" button

The program will use AppID, the Program Import SDK must be associated with the application of the SDK, downloaded the SDK compression package is named after the AppID end.

Second, the project configuration

Official Document: Http://www.xfyun.cn/doccenter/iOS

1. Add a static library

Follow the iOS libraries you need to add the SDK, and be aware that libz.dylib,coretelephoney.framework is not missing.

Note: If you are using offline identification, you also need to add libc++.dylib.

2. Initialization

The speech service must be initialized before it can be used, and initialization is an asynchronous process, which is recommended at the entrance of the program.

AppID is the identity information of the app and is unique, and must be passed in to AppID when initialized. You can view this information from the demo's Definition.h Appid_value. Demo and SDK application address: http://xfyun.cn

Initialize in APPDELEGATE.M's didfinishlaunchingwithoptions: Method

First import the header file:

#import "Iflymsc/iflyspeechutility.h"

1-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions {2     //Override point for customization after application launch.3     //sign in to the Iflytek voice platform4NSString *initstring = [[NSString alloc] Initwithformat:@"appid=%@",@"5750da0e"];5 [iflyspeechutility createutility:initstring];6     returnYES;7}
