1.導入依賴庫
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
注意還要導入依賴庫：CoreTelephony.framework
2.需要包含的SDK文件有：
從開放平台下載的包里面的
Headers文件夾、Third Part文件夾、還有..resources文件夾(tone和scheme)、還有.a靜態庫文件
3.將工程的bitcode設置為NO
4.build Setting里面設置other linker flags為-ObjC
示例Demo：
#import "ViewController.h"
#import "BDVoiceRecognitionClient.h"
@interface ViewController ()<MVoiceRecognitionClientDelegate>
@end
@implementation ViewController

[super viewDidLoad];

[[BDVoiceRecognitionClient sharedInstance] cancelListenCurrentDBLevelMeter];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

//設置識別垂類

//設置識別語言為普通話
[client setLanguage:EVoiceRecognitionPropertyMusic];
//禁用標點符號<默認不禁用>
[client disablePuncs:YES];
//設置是否對語音進行端點檢測，即SDK會自動判斷說話是否結束<默認開啟>
[client setNeedVadFlag:YES];
//設置是否對上傳的語音進行壓縮<默認壓縮>

//設置在線識別的響應等待時間,如果超時,觸發同步離線識別

//開始說話開始提示音
