目前开放的服务：
准备工作
需要到讯飞官网注册一个开发账号，注册后登录并创建一个新的应用，添加需要的服务(语音听写、语音合成等等)，应用创建后可以得到一个Appid，这个要在开发中初始化讯飞语音应用中用到。
工程中找到Targets->Build Phases->Link Binary With Libraries，添加下面的库，注意iflyMSC.framework下载后一定要保证导入到工程目录下，而不能只是个路径引用否则会报错。另外需要在Build Settings的Build Options中关闭BitCode。
在需要的地方引入讯飞语音库头文件，当然可以根据需要只引入某种服务的头文件
#import <iflyMSC/iflyMSC.h> // 引入讯飞语音库
#ifndef MSC_IFlyMSC_h#define MSC_IFlyMSC_h#import "IFlyAudioSession.h"#import "IFlyContact.h"#import "IFlyDataUploader.h"#import "IFlyDebugLog.h"#import "IFlyISVDelegate.h"#import "IFlyISVRecognizer.h"#import "IFlyRecognizerView.h"#import "IFlyRecognizerViewDelegate.h"#import "IFlyResourceUtil.h"#import "IFlySetting.h"#import "IFlySpeechConstant.h"#import "IFlySpeechError.h"#import "IFlySpeechEvaluator.h"#import "IFlySpeechEvaluatorDelegate.h"#import "IFlySpeechEvent.h"#import "IFlySpeechRecognizer.h"#import "IFlySpeechRecognizerDelegate.h"#import "IFlySpeechSynthesizer.h"#import "IFlySpeechSynthesizerDelegate.h"#import "IFlySpeechUnderstander.h"#import "IFlySpeechUtility.h"#import "IFlyTextUnderstander.h"#import "IFlyUserWords.h"#import "IFlyPcmRecorder.h"#import "IFlyVoiceWakeuper.h"#import "IFlyVoiceWakeuperDelegate.h"#endif
使用Appid初始化讯飞应用，在应用启动的地方使用Appid初始化语音应用，这里放在了AppDelegate应用代理文件下：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {// Override point for customization after application launch.NSString *initString = [[NSString alloc] initWithFormat:@"appid=%@",@"587f6174"];[IFlySpeechUtility createUtility:initString];return YES;}
语音合成和语音测评示例
这里因为要使用语音合成和测评功能所以先测试了这两个，其他的类似，可参考官方文档：
应用启动后会有‘小燕’的声音读出：”Hello, this is xiaoyan!”应用启动后测评”Today is a sunny day!”的发音
先要使用Appid初始化:
