百度语音识别

一、接入指南

先引入编译需要的Framework：

AudioToolbox.framework

AVFoundation.framework

SystemConfiguration.framework

CoreTelephony.framework

Security.framework

libz.1.tbd

CFNetwork.framework

CoreLocation.framework

OpenGLES.framework

QuartzCore.framework

GLKit.framework

CoreGraphics.framework

CoreText.framework

---

二、导入Baidu-Voice-SDK-iOS-1

1.其中BDVoiceRecognitionClientResources为蓝色

2.导入JSONKit.h和JSONKit.m文件

3.Build Phases中JSONKit.m添加-fno-objc-arc

三、在ViewController中

---

1、导入头文件

#import "BDRecognizerViewController.h"

#import "BDRecognizerViewDelegate.h"

#import "BDVoiceRecognitionClient.h"

#import "BDVRRawDataRecognizer.h"

#import "BDVRFileRecognizer.h"

---

2、添加协议BDRecognizerViewDelegate

@interface ViewController (){

BDRecognizerViewController *bdv;

//参数设置 key 秘钥

BDRecognizerViewParamsObject *bdf;

NSMutableData *allData;

}

---

3、在- (void)viewDidLoad显示

//设置主题样式

BDTheme *theme = [BDTheme lightOrangeTheme];

// 创建识别控件

bdv = [[BDRecognizerViewController alloc] initWithOrigin:CGPointMake(9, 128) withTheme:theme];

// 全屏UI

bdv.enableFullScreenMode = YES;

// 设置委托

bdv.delegate = self;

bdf = [[BDRecognizerViewParamsObject alloc]init];

//bdf.productID 不用设置

bdf.apiKey = @"ANQLQINhgf2TL0gVP5xhNCxm";

bdf.secretKey = @"c3d5f5f8ac5478e87802431389b2cba7";

---

3、按钮

- (IBAction)BByy:(id)sender {

allData = [[NSMutableData alloc]init];

[bdv startWithParams:bdf];

}

---

4、协议中的方法

/**

* @brief 语音识别结果返回，搜索和输入模式结果返回的结构不相同

*

* @param aBDRecognizerView 弹窗UI

* @param aResults 返回结果，搜索结果为数组，输入结果也为数组，但元素为字典

*/

- (void)onEndWithViews:(BDRecognizerViewController *)aBDRecognizerViewController withResults:(NSArray *)aResults{

NSLog(@"==2======%@",[[[[aResults lastObject]lastObject] allKeys] lastObject] );

self.textIF.text =[[[[aResults lastObject]lastObject] allKeys] lastObject];

}

/**

* @brief 录音数据返回

*

* @param recordData 录音数据

* @param sampleRate 采样率

*/

- (void)onRecordDataArrived:(NSData *)recordData sampleRate:(int)sampleRate{

[allData appendData:recordData];

}
