一、下载讯飞的SDK

二、集成流程

第一步：获取appid（进入控制台查看）

第二步：工程配置

1、将模板项目的lib文件拉入项目，并加入依赖库

注意： 添加iflyMSC.framework时，请检查工程BuildSetting中的framwork path的设置，如果出现找不到framework的情况，可以将path清空，在Xcode中删除framework，然后重新添加。 如果使用了离线识别，还需要增加libc++.tbd。 如果使用aiui，需要添加libc++.tbd，libicucord.tbd。

2、设置Bitcode

在Xcode 7,8默认开启了Bitcode，而Bitcode 需要工程依赖的所有类库同时支持。MSC SDK暂时还不支持Bitcode，可以先临时关闭。后续MSC SDK支持Bitcode 时，会在讯飞开放平台上进行SDK版本更新，QQ支持群中同时会有相关提醒，请关注。关闭此设置，只需在Targets - Build Settings 中搜索Bitcode 即可，找到相应选项，设置为NO。

3、用户隐私权限配置

iOS 10发布以来，苹果为了用户信息安全，加入隐私权限设置机制，让用户来选择是否允许。 隐私权限配置可在info.plist 新增相关privacy字段，MSC SDK中需要用到的权限主要包括麦克风权限、联系人权限和地理位置权限：

NSMicrophoneUsageDescription

NSLocationUsageDescription

NSLocationAlwaysUsageDescription

NSContactsUsageDescription

即在Info.plist 中增加下图设置：

第1种设置方法：

第2种设置方法：

第三步：初始化

初始化示例：

//可在启动时添加，Appid是应用的身份信息，具有唯一性，初始化时必须要传入Appid。

NSString *initString = [[NSString alloc] initWithFormat:@"appid=%@", @"YourAppid"];

[IFlySpeechUtility createUtility:initString];

注意： 初始化是一个异步过程，可放在App启动时执行初始化，具体代码可以参照Demo的MSCAppDelegate.m。

还需要在工程中添加结果解析文件，否则编译会报错。

文件在Demo中的位置：MSCDemo -> tools -> jsoncpp

还需要从模板项目中拖拽IATConfig类和ISRDataHelper类到自己的项目中

三、下面就是具体代码操作

1、语音在线合成

本示例对应Demo的TTSUIController文件，为在线合成的代码示例。

//包含头文件
#import "iflyMSC/IFlyMSC.h"
//需要实现IFlySpeechSynthesizerDelegate合成会话的服务代理
@interface TTSUIController : UIViewController<IFlySpeechSynthesizerDelegate>
@property (nonatomic, strong) IFlySpeechSynthesizer *iFlySpeechSynthesizer;
@end//获取语音合成单例
_iFlySpeechSynthesizer = [IFlySpeechSynthesizer sharedInstance];
//设置协议委托对象
_iFlySpeechSynthesizer.delegate = self;
//设置合成参数
//设置在线工作方式
[_iFlySpeechSynthesizer setParameter:[IFlySpeechConstant TYPE_CLOUD]  forKey:[IFlySpeechConstant ENGINE_TYPE]];
//设置音量，取值范围 0~100
[_iFlySpeechSynthesizer setParameter:@"50" forKey: [IFlySpeechConstant VOLUME]];
//发音人，默认为”xiaoyan”，可以设置的参数列表可参考“合成发音人列表”
[_iFlySpeechSynthesizer setParameter:@" xiaoyan "forKey: [IFlySpeechConstant VOICE_NAME]];
//保存合成文件名，如不再需要，设置为nil或者为空表示取消，默认目录位于library/cache下
[_iFlySpeechSynthesizer setParameter:@" tts.pcm" forKey: [IFlySpeechConstant TTS_AUDIO_PATH]];
//启动合成会话
[_iFlySpeechSynthesizer startSpeaking: @"你好，我是科大讯飞的小燕"];//IFlySpeechSynthesizerDelegate协议实现
//合成结束
- (void) onCompleted:(IFlySpeechError *) error {}
//合成开始
- (void) onSpeakBegin {}
//合成缓冲进度
- (void) onBufferProgress:(int) progress message:(NSString *)msg {}
//合成播放进度
- (void) onSpeakProgress:(int) progress beginPos:(int)beginPos endPos:(int)endPos {}

2、语音听写（带界面的例子） IFlySpeechRecognizer是不带界面的语音听写控件，IFlyRecognizerView是带界面的控件，此处仅介绍不带界面的语音听写控件。在ViewController.m中写的，可以直接测试

使用示例如下所示：

//
//  ViewController.m
//  文字语音读写

{if ([IATConfig sharedInstance].haveView == NO) {[_iFlySpeechRecognizer setParameter:@"1" forKey:[IFlySpeechConstant ASR_SCH]];if(langIsZh){[_iFlySpeechRecognizer setParameter:@"cn" forKey:@"orilang"];[_iFlySpeechRecognizer setParameter:@"en" forKey:@"translang"];}else{[_iFlySpeechRecognizer setParameter:@"en" forKey:@"orilang"];[_iFlySpeechRecognizer setParameter:@"cn" forKey:@"translang"];}[_iFlySpeechRecognizer setParameter:@"translate" forKey:@"addcap"];[_iFlySpeechRecognizer setParameter:@"its" forKey:@"trssrc"];}else{[_iflyRecognizerView setParameter:@"1" forKey:[IFlySpeechConstant ASR_SCH]];if(langIsZh){[_iflyRecognizerView setParameter:@"cn" forKey:@"orilang"];[_iflyRecognizerView setParameter:@"en" forKey:@"translang"];}else{[_iflyRecognizerView setParameter:@"en" forKey:@"orilang"];[_iflyRecognizerView setParameter:@"cn" forKey:@"translang"];}[_iflyRecognizerView setParameter:@"translate" forKey:@"addcap"];[_iflyRecognizerView setParameter:@"its" forKey:@"trssrc"];}}- (void)viewDidLoad {[super viewDidLoad];_resultARR = [[NSMutableArray alloc]init];if(_iflyRecognizerView == nil){[self initRecognizer ];}//Set microphone as audio source[_iflyRecognizerView setParameter:IFLY_AUDIO_SOURCE_MIC forKey:@"audio_source"];//Set result type[_iflyRecognizerView setParameter:@"plain" forKey:[IFlySpeechConstant RESULT_TYPE]];//Set the audio name of saved recording file while is generated in the local storage path of SDK,by default in library/cache.[_iflyRecognizerView setParameter:@"asr.pcm" forKey:[IFlySpeechConstant ASR_AUDIO_PATH]];UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];btn.backgroundColor = [UIColor redColor];btn.frame = CGRectMake(200, 300, 100, 60);[btn addTarget:self action:@selector(btnClick1:) forControlEvents:UIControlEventTouchUpInside];btn.selected = NO;[self.view addSubview:btn];[self setExclusiveTouchForButtons:self.view];}-(void)setExclusiveTouchForButtons:(UIView *)myView
{for (UIView * button in [myView subviews]) {if([button isKindOfClass:[UIButton class]]){[((UIButton *)button) setExclusiveTouch:YES];}else if ([button isKindOfClass:[UIView class]]){[self setExclusiveTouchForButtons:button];}}
}- (void)btnClick1:(UIButton *)btn{[_resultARR removeAllObjects];//启动识别服务[_iflyRecognizerView start];}/*!*  回调返回识别结果**  @param resultArray 识别结果，NSArray的第一个元素为NSDictionary，NSDictionary的key为识别结果，sc为识别结果的置信度*  @param isLast      -[out] 是否最后一个结果*/
- (void)onResult:(NSArray *)resultArray isLast:(BOOL) isLast{NSMutableString *resultString = [[NSMutableString alloc] init];NSDictionary *dic = [resultArray objectAtIndex:0];NSLog(@"%@",dic);for (NSString *key in dic) {[resultString appendFormat:@"%@",key];}NSString * resultFromJson =  nil;if([IATConfig sharedInstance].isTranslate){NSDictionary *resultDic  = [NSJSONSerialization JSONObjectWithData:    //The result type must be utf8, otherwise an unknown error will happen.[resultString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:nil];if(resultDic != nil){NSDictionary *trans_result = [resultDic objectForKey:@"trans_result"];NSString *src = [trans_result objectForKey:@"src"];NSLog(@"src=%@",src);resultFromJson = [NSString stringWithFormat:@"%@\nsrc:%@",resultString,src];}}else{resultFromJson = [NSString stringWithFormat:@"%@",resultString];//;[ISRDataHelper stringFromJson:resultString];}[_resultARR addObject:resultFromJson];}/*!*  识别结束回调**  @param error 识别结束错误码*/
- (void)onError: (IFlySpeechError *) error{NSLog(@"errorCode:%d",[error errorCode]);NSString *resultStr = [_resultARR componentsJoinedByString:@" "];UIAlertView *alertV = [[UIAlertView alloc]initWithTitle:@"" message:resultStr delegate:self cancelButtonTitle:@"cancle" otherButtonTitles:nil];[alertV show];}- (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];// Dispose of any resources that can be recreated.
}@end

效果图：

最后，为了提高语音识别精确读，在程序启动时加入以下代码

#pragma mark----------语音转文字时需要精确辨别的词----------
- (void)setWordsIUsed{//用户词表
#define USERWORDS   @"{\"userword\":[{\"name\":\"iflytek\",\"words\":[\"指动生活\",\"指动\",\"生活\",\"温馨提示\",\"温馨\",\"提示\",\"家园活动\",\"家园\",\"活动\",\"智能门禁\",\"智能\",\"门禁\",\"投诉报修\",\"投诉\",\"报修\",\"物业缴费\",\"交费\",\"缴费\"]}]}"//创建上传对象_uploader = [[IFlyDataUploader alloc] init];IFlyUserWords *iFlyUserWords = [[IFlyUserWords alloc] initWithJson:USERWORDS ];//设置上传参数[_uploader setParameter:@"uup" forKey:@"sub"];[_uploader setParameter:@"userword" forKey:@"dtt"];//启动上传（请注意name参数的不同）[_uploader uploadDataWithCompletionHandler:^(NSString * grammerID, IFlySpeechError *error){//}name: @"userwords" data:[iFlyUserWords toString]];}
