接入百度语音SDK的步骤
1.导入依赖库
SystemConfiguration.framework
AudioToolbox.framework
UIkit.framework
AVFoundation.framework
Foundation.framework
libz.tbd
Security.framework
QuartzCore.framework
CoreText.framework
GLKit.framework
OpenGLES.framework
CoreLocation.framework
CFNetwork.framework
CoreGraphics.framework
注意还要导入依赖库：CoreTelephony.framework
2.需要包含的SDK文件有：
从开放平台下载的包里面的
Headers文件夹、Third Part文件夹、还有..resources文件夹(tone和scheme)、还有.a静态库文件
3.将工程的bitcode设置为NO
4.build Setting里面设置other linker flags为-ObjC
示例Demo：
#import "ViewController.h"
#import "BDVoiceRecognitionClient.h"
@interface ViewController ()<MVoiceRecognitionClientDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
//取消监听语音音量
[[BDVoiceRecognitionClient sharedInstance] cancelListenCurrentDBLevelMeter];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)inputBtnClick:(id)sender {
BDVoiceRecognitionClient * client = [BDVoiceRecognitionClient sharedInstance];
[client setApiKey:@"Au2wN2SaDOpYZHgGqrIymMkU" withSecretKey:@"a0212d1fa0f28699aa5d1162a1bcbf1c"];
//设置识别垂类
//[client setPropertyList:@[[NSNumber numberWithInt:EVoiceRecognitionPropertyVideo]]];
//设置识别语言为普通话
[client setLanguage:EVoiceRecognitionPropertyMusic];
//禁用标点符号<默认不禁用>
[client disablePuncs:YES];
//设置是否对语音进行端点检测，即SDK会自动判断说话是否结束<默认开启>
[client setNeedVadFlag:YES];
//设置是否对上传的语音进行压缩<默认压缩>
[client setNeedCompressFlag:YES];
//设置在线识别的响应等待时间,如果超时,触发同步离线识别
[client setOnlineWaitTime:5];
//开启自然语言理解结果
[client setConfig:@"nlu" withFlag:YES];
//开始说话开始提示音
[client setPlayTone:EVoiceRecognitionPlayTonesRecStart isPlay:YES];
//开始说话结束提示音
[client setPlayTone:EVoiceRecognitionPlayTonesRecEnd isPlay:YES];
//打开语音音量功能
[client listenCurrentDBLevelMeter];
//获取当前语音音量级别
[client getCurrentDBLevelMeter];
