iOS 使用科大讯飞技术实现语音转文字(语音听写)

本文主要介绍的是利用科大讯飞技术实现语音转文字的功能(语音听写).

首先,注册讯飞账号，申请APPID
然后,下载科大讯飞SDK将开发工具包中lib目录下的iflyMSC.framework添加到新建工程中.

按下图添加SDK所需要的iOS库。(除iflyMSC.framework,iflyMSC.framework是拖进去的)

接着,在appDelegate中引入头文件

#import “iflyMSC/IFlyRecognizerViewDelegate.h”  

#import “iflyMSC/IFlyRecognizerView.h”  

写上代码

  NSString *appid =
@"********";//自己申请的appId

  NSString *initString = [NSString
stringWithFormat:@"appid=%@",appid];

  [IFlySpeechUtility
createUtility:initString];

在相应的viewController里:

遵守协议<IFlyRecognizerViewDelegate>

@property (nonatomic,strong)IFlyRecognizerView *iflyRecognizerView;

- (void)viewDidLoad {

    [super
viewDidLoad];

    

    self.iflyRecognizerView = [[IFlyRecognizerView
alloc]initWithCenter:self.view.center];

    self.iflyRecognizerView.delegate =
self;

    [self.view
addSubview:self.iflyRecognizerView];

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

    //asr_audio_path保存录音文件名,默认目录是documents

    [self.iflyRecognizerView
setParameter: @"asrview.pcm"
forKey:[IFlySpeechConstant
ASR_AUDIO_PATH]];

   
//设置返回的数据格式为默认plain

    [self.iflyRecognizerView
setParameter:@"plain"
forKey:[IFlySpeechConstant
RESULT_TYPE]];

    [self startListenning:self.iflyRecognizerView];//可以建一个按钮,点击按钮调用此方法

}

- (void)startListenning:(id)sender{

    [self.iflyRecognizerView
start];

    NSLog(@"开始识别");

}

//返回数据处理

- (void)onResult:(NSArray *)resultArray isLast:(BOOL)isLast

{

    NSMutableString *result = [NSMutableString
new];

    NSDictionary *dic = [resultArray
objectAtIndex:0];

    NSLog(@"DIC:%@",dic);

    for (NSString *key
in dic) {

        [result appendFormat:@"%@",key];

    }

//把相应的控件赋值为result.例如:label.text = result;

}

- (void)onError:(IFlySpeechError *)error

{

    

}

这样就实现了利用科大讯飞语音转文字的功能.
