科大訊飛語音識別

先到科大訊飛開放平臺註冊帳號，建立應用並下載SDK，解壓SDK壓縮包，將framework拖到工程中，以下圖

而後還要導入一下類庫：具體以下圖

建立一個工程，咱們分紅兩部分，第一部分就是在FristViewController中，實現語音識別功能，第二部分就是在SecondViewController中，實現文字轉換爲語音

首先在AppDelegate.m導入頭文件

1 // 導入頭文件
2 #import <iflyMSC/iflyMSC.h>

而後在AppDelegate.m中實現登陸科大訊飛語音平臺

1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
2     // Override point for customization after application launch.
3     
4     // 第二步：登陸科大訊飛語音平臺 【換成本身的訊飛應用id就好了】
5     NSString *appID = [NSString stringWithFormat:@"appid=%@",@"5750da61"];
6     [IFlySpeechUtility createUtility:appID];
7     
8     return YES;
9 }

到了第一部分的實現了，直接上代碼【FirstViewController.m】

 1 #import "FirstViewController.h"
 2 //第一步：引入庫文件
 3 //科大訊飛語音識別功能回調方法的接口文件
 4 #import <iflyMSC/IFlyRecognizerViewDelegate.h>
 5 //科大訊飛語音識別功能的聲音識別視圖
 6 #import <iflyMSC/IFlyRecognizerView.h>
 7 //科大訊飛語音識別功能中定義的常量
 8 #import <iflyMSC/IFlySpeechConstant.h>

10 @interface FirstViewController () <IFlyRecognizerViewDelegate>  // 遵循代理
11 
12 /**  textView  */
13 @property (weak, nonatomic) IBOutlet UITextView *textView;
14 
15 /**  語音識別對象  */

26     [super viewDidLoad];
27     // Do any additional setup after loading the view.
28     
29     
30     //建立聲音識別視圖對象,初始化聲音識別控件
31     self.iflyRecognizerView= [[IFlyRecognizerView alloc] initWithCenter:self.view.center];
32     //delegate須要設置，確保delegate回調能夠正常返回
33     self.iflyRecognizerView.delegate = self;
34 }

46 {

48     [self.iflyRecognizerView setParameter: @"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]];

50     [self.iflyRecognizerView setParameter: @"6000" forKey:[IFlySpeechConstant VAD_BOS]];

60     [self.iflyRecognizerView setParameter: @"temp.asr" forKey:[IFlySpeechConstant ASR_AUDIO_PATH]];

62     [self.iflyRecognizerView setParameter: @"custom" forKey:[IFlySpeechConstant PARAMS]];
63     
64     [self.iflyRecognizerView start];
65 }
