一、首先到科大讯飞官网注册账号(http://open.voicecloud.cn/),并创建应用获取appid,下载sdk文件
二、代码实现api调用
1.先用xcode(我这里使用的是xcode 5.1)新建好一个项目,然后在项目添加要用的类库。其中有一个是讯飞语音的类库iflyMSC,在下载的sdk文件里有,导入就行了。导入的时候要注意把iflyMSC类库拷贝到你的工程目录里,不然后果很严重!
2.导完类库之后,在建好的工程里添加好要用的头文件。
MainViewController.h

#import <UIKit/UIKit.h>
#import "iflyMSC/IFlySpeechSynthesizerDelegate.h"

MainViewController.m

#import <QuartzCore/QuartzCore.h>
#import <AVFoundation/AVAudioSession.h>
#import <AudioToolbox/AudioSession.h>
#import "iflyMSC/IFlySpeechConstant.h"
#import "iflyMSC/IFlySpeechUtility.h"
#import "iflyMSC/IFlySpeechSynthesizer.h"
|
3.完成这些准备工作之后,接下来就是堆代码的工作了。为了方便,笔者只用了两个控件:一个UITextField、一个UIButton,然后给这两个控件分别做一个Outlet和Action连接。
