一.集成
-
首先到 http://www.xfyun.cn 注册并登陆下
1 创建新应用(获得后续的appid以及开通服务)

2 得到appid,点击开通服务选择->语音听写,自动跳转下载sdk界面

新建工程开始集成
1.添加系统库<libz.tbd,AVFoundation.framework,SystemConfiguration.framework,Foundation.framework,CoreTelephoney.framework,AudioToolbox.framework,UIKit.framework,CoreLocation.framework,AddressBook.framework,AddressBook.framework,AddressBook.framework>

2.添加iflyMSC.framework(在下载的ZIP->lib 目录下)

二.初始化
1.AppDelegate添加如下代码
//设置sdk的log等级，log保存在下面设置的工作路径中
[IFlySetting setLogFile:LVL_ALL];
// 打开输出在console的log开关
[IFlySetting showLogcat:YES];
//设置sdk的工作路径
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachePath = [paths objectAtIndex:0];
[IFlySetting setLogFilePath:cachePath];
NSString *initString = [[NSString alloc] initWithFormat:@"appid=%@",@"573b1d27"];
[IFlySpeechUtility createUtility:initString];
2.讯飞的语音识别主要有2个类 **IFlySpeechRecognizer(不带界面)** 和 **IFlyRecognizerView(界面)**,用法差不多,主要介绍带界面的用法.
- (IFlyRecognizerView *)iflyRecognizerView{
if (!_iflyRecognizerView) {
IFlyRecognizerView *iflyRecognizerView = [[IFlyRecognizerView alloc] initWithCenter:self.view.center];
iflyRecognizerView.delegate = self;
[iflyRecognizerView setParameter:@"" forKey:[IFlySpeechConstant PARAMS]];
//设置听写模式
[iflyRecognizerView setParameter:@"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]];
IATConfig *instance = [IATConfig sharedInstance];
//设置最长录音时间
[iflyRecognizerView setParameter:instance.speechTimeout forKey:[IFlySpeechConstant SPEECH_TIMEOUT]];
//设置后端点
[iflyRecognizerView setParameter:instance.vadEos forKey:[IFlySpeechConstant VAD_EOS]];
//设置前端点
[iflyRecognizerView setParameter:instance.vadBos forKey:[IFlySpeechConstant VAD_BOS]];
//网络等待时间
[iflyRecognizerView setParameter:@"20000" forKey:[IFlySpeechConstant NET_TIMEOUT]];
//设置采样率，推荐使用16K
[iflyRecognizerView setParameter:instance.sampleRate forKey:[IFlySpeechConstant SAMPLE_RATE]];
if ([instance.language isEqualToString:[IATConfig chinese]]) {
//设置语言
[iflyRecognizerView setParameter:instance.language forKey:[IFlySpeechConstant LANGUAGE]];
//设置方言
[iflyRecognizerView setParameter:instance.accent forKey:[IFlySpeechConstant ACCENT]];
}else if ([instance.language isEqualToString:[IATConfig english]]) {
//设置语言
[iflyRecognizerView setParameter:instance.language forKey:[IFlySpeechConstant LANGUAGE]];
}
//设置是否返回标点符号
[iflyRecognizerView setParameter:instance.dot forKey:[IFlySpeechConstant ASR_PTT]];
self.iflyRecognizerView = iflyRecognizerView;
}
return _iflyRecognizerView;
}
````
然后启动服务 [self.iflyRecognizerView start];
3 然后通过代理 IFlyRecognizerViewDelegate 该代理就2个方法如下
/*!
* 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;
/*!
* 识别结束回调
*
* @param error 识别结束错误码
*/
- (void)onError: (IFlySpeechError *) error;
三.代理模式到Block的转换(简单封装)
1.抽取一个工具类,通过block传递结果
/**
* 回调
*/
typedef void (^RecognizerBlock)(IFlySpeechError *error,NSString *result);
@interface ZZiflyTool : NSObject
+ (instancetype)shareTool;
- (void)startRecognizer:(RecognizerBlock)block;
@end
外界只需要一句话就可以调用了
[[ZZiflyTool shareTool] startRecognizer:^(IFlySpeechError *error, NSString *result) {
if (error) {
[self showMes:error.errorDesc];
return;
}
NSString *str = result.length ? result:@"没听到你说啥";
[self showMes:str];
}];
