iOS_科大讯飞快速实现语音搜索功能Demo

配置工程看开发文档就行了,本Demo就是创建一个按钮和显示语音搜索结果的文本框:直接上代码:

#import "ViewController.h"
#import <iflyMSC/iflyMSC.h>

@interface ViewController ()<IFlyRecognizerViewDelegate>

@property (nonatomic, strong) IFlyRecognizerView *iFlyRecognizerView;
@property (nonatomic, strong) NSString *result;/**< 显示结果的字符串 */
@property (nonatomic, strong) UIButton *button;/**< 点击开始的录音按钮 */
@property (nonatomic, assign) BOOL isStart; /**< 是否录音的状态 */
@property (nonatomic, strong) UILabel *titleLabel; /**< 显示语音结果的lable */



@end

@implementation ViewController

    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.isStart = NO;

    //1.创建语音听写对象
    self.iFlyRecognizerView = [[IFlyRecognizerView alloc] initWithCenter:self.view.center];
    
    
    
    //2.设置听写参数
    [_iFlyRecognizerView setParameter:@"iat" forKey:[IFlySpeechConstant IFLY_DOMAIN]];
    
    //asr_audio_path是录音文件名,设置value为nil或者为空取消保存,默认保存目录在 Library/cache下。
