科大讯飞语音识别
先到科大讯飞开放平台注册帐号，建立应用并下载SDK，解压SDK压缩包，将framework拖到工程中，以下图前端
而后还要导入一下类库：具体以下图后端
建立一个工程，咱们分红两部分，第一部分就是在FristViewController中，实现语音识别功能，第二部分就是在SecondViewController中，实现文字转换为语音缓存
首先在AppDelegate.m导入头文件数据结构
1 // 导入头文件 2 #import <iflyMSC/iflyMSC.h>
而后在AppDelegate.m中实现登陆科大讯飞语音平台app
1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 2 // Override point for customization after application launch. 3 4 // 第二步：登陆科大讯飞语音平台 【换成本身的讯飞应用id就好了】 5 NSString *appID = [NSString stringWithFormat:@"appid=%@",@"5750da61"]; 6 [IFlySpeechUtility createUtility:appID]; 7 8 return YES; 9 }
到了第一部分的实现了，直接上代码【FirstViewController.m】框架
1 #import "FirstViewController.h" 2 //第一步：引入库文件 3 //科大讯飞语音识别功能回调方法的接口文件 4 #import <iflyMSC/IFlyRecognizerViewDelegate.h> 5 //科大讯飞语音识别功能的声音识别视图 6 #import <iflyMSC/IFlyRecognizerView.h> 7 //科大讯飞语音识别功能中定义的常量 8 #import <iflyMSC/IFlySpeechConstant.h> 9 10 @interface FirstViewController () <IFlyRecognizerViewDelegate> // 遵循代理 11 12 /** textView */ 13 @property (weak, nonatomic) IBOutlet UITextView *textView; 14 15 /** 语音识别对象 */ 16 @property (nonatomic, strong) IFlyRecognizerView *iflyRecognizerView; 17 18 /** 接收相关结果的字符串 */ 19 @property (nonatomic, strong) NSMutableString *result; 20 21 @end 22 23 @implementation FirstViewController 24 25 - (void)viewDidLoad { 26 [super viewDidLoad]; 27 // Do any additional setup after loading the view. 28 29 30 //建立声音识别视图对象,初始化声音识别控件 31 self.iflyRecognizerView= [[IFlyRecognizerView alloc] initWithCenter:self.view.center]; 32 //delegate须要设置，确保delegate回调能够正常返回 33 self.iflyRecognizerView.delegate = self; 34 } 35 36 37 #pragma mark - 开始识别 38 - (IBAction)beginRecongnise:(id)sender { 39 40 [self startListenning]; 41 } 42 43 44 // 语音识别 45 - (void)startListenning 46 { 47 //设置语音识别结果应用为普通文本领域 48 [self.iflyRecognizerView setParameter: @"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]]; 49 //设置前端点检测时间为6000ms 50 [self.iflyRecognizerView setParameter: @"6000" forKey:[IFlySpeechConstant VAD_BOS]]; 51 //设置后端点检测时间为700ms 52 [self.iflyRecognizerView setParameter: @"700" forKey:[IFlySpeechConstant VAD_EOS]]; 53 //设置采样率为8000 54 [self.iflyRecognizerView setParameter: @"8000" forKey:[IFlySpeechConstant SAMPLE_RATE]]; 55 //设置为返回结果中包含标点符号 56 [self.iflyRecognizerView setParameter: @"1" forKey:[IFlySpeechConstant ASR_PTT]]; 57 //设置语音识别完成后数据的返回数据结构类型xml 58 [self.iflyRecognizerView setParameter: @"plain" forKey:[IFlySpeechConstant RESULT_TYPE]]; 59 //设置在Documents文件夹下缓存的文件名为temp.asr 60 [self.iflyRecognizerView setParameter: @"temp.asr" forKey:[IFlySpeechConstant ASR_AUDIO_PATH]]; 61 //设置自定义的参数 62 [self.iflyRecognizerView setParameter: @"custom" forKey:[IFlySpeechConstant PARAMS]]; 63 64 [self.iflyRecognizerView start]; 65 } 66 67 68 #pragma mark - 代理方法 69 // 成功 70 - (void)onResult:(NSArray *)resultArray isLast:(BOOL)isLast { 71 72 self.result = [[NSMutableString alloc] init]; 73 NSDictionary *dic = [resultArray objectAtIndex:0]; 74 75 for (NSString *key in dic) 76 { 77 [self.result appendFormat:@"%@",key]; 78 } 79 NSLog(@"%@---------",_result); 80 81 // 自定义控件显示内容 82 self.textView.text = [NSString stringWithFormat:@"%@%@",self.textView.text,self.result]; 83 } 84 85 86 // 失败 87 - (void)onError:(IFlySpeechError *)error { 88 89 } 90 91 @end
实现第二部分【SecondViewController.m】ide
1 #import "SecondViewController.h" 2 3 //文字识别的回调方法接口 4 #import <iflyMSC/IFlySpeechSynthesizerDelegate.h> 5 //文字识别对象 6 #import <iflyMSC/IFlySpeechSynthesizer.h> 7 //科大讯飞语音框架定义的常量 8 #import <iflyMSC/IFlySpeechConstant.h> 9 10 @interface SecondViewController () <IFlySpeechSynthesizerDelegate> // 遵循相关代理 11 12 /** textView */ 13 @property (weak, nonatomic) IBOutlet UITextView *textView; 14 15 /** 文字识别对象 */ 16 @property (strong, nonatomic) IFlySpeechSynthesizer *synthesizer; 17 18 @end 19 20 @implementation SecondViewController 21 22 - (void)viewDidLoad { 23 [super viewDidLoad]; 24 25 26 //建立文字识别对象 27 self.synthesizer = [IFlySpeechSynthesizer sharedInstance]; 28 29 //指定文字识别对象的代理对象 30 self.synthesizer.delegate = self; 31 32 //设置文字识别对象的关键属性 33 [self.synthesizer setParameter:@"50" forKey:[IFlySpeechConstant SPEED]]; 34 [self.synthesizer setParameter:@"50" forKey:[IFlySpeechConstant VOLUME]]; 35 [self.synthesizer setParameter:@"XIAOYAN" forKey:[IFlySpeechConstant VOICE_NAME]]; 36 [self.synthesizer setParameter:@"8000" forKey:[IFlySpeechConstant SAMPLE_RATE]]; 37 [self.synthesizer setParameter:@"temp.pcm" forKey:[IFlySpeechConstant TTS_AUDIO_PATH]]; 38 [self.synthesizer setParameter:@"custom" forKey:[IFlySpeechConstant PARAMS]]; 39 } 40 41 42 #pragma mark - 识别相关的内容 43 - (IBAction)beginRecognise:(id)sender { 44 45 [self.synthesizer startSpeaking:_textView.text]; 46 } 47 48 49 #pragma mark - 代理方法 50 - (void)onCompleted:(IFlySpeechError *)error { 51 52 NSLog(@""); 53 } 54 55 @end
