前言：此博客内容有，集成讯飞语音sdk，实现了语音唤醒，在线语音识别，离线语音识别，更新本地离线语音词典
集成讯飞语音SDK
注册账号下载SDK
百度搜索科大讯飞，打开网站，没有账号的根据操作步骤注册账号，注册完成之后，根据个人需求下载sdk，因为咱们要实现的内容有离线语音识别，语音唤醒，以及更新本地离线语音字典，所以在下载SDK之前需要添加唤醒词，添加完之后再去下载SDK
导入demo
导入demo，有可能会报错，怕大家不知道怎么解决，这里我就给大家详细介绍一下，会遇到的一些问题都是怎么解决的；
先导入demo
导入demo后我的会报着个错误
ERROR: Plugin with id 'com.android.application' not found.
Open File
我们仔细观察会发现此项目结构中只有 Project 的build.grade 文件，没有Module 的 build.grade，所以我们在 Project 的build.gradle中添加如下代码，然后try again
buildscript {repositories {google()jcenter()}dependencies {//版本号请根据自己的gradle插件版本号自行更改classpath 'com.android.tools.build:gradle:3.2.0'}
}
在这里需要注意一下，buildscript 、 android 和 dependencies 他们三个是同级的关系，如下图
同步完之后我的又报如下错误
ERROR: The minSdk version should not be declared in the android manifest file. You can move the version from the manifest to the defaultConfig in the build.gradle file.
Remove minSdkVersion and sync project
Affected Modules: mscV5PlusDemoWARNING: The specified Android SDK Build Tools version (26.0.2) is ignored, as it is below the minimum supported version (28.0.2) for Android Gradle Plugin 3.2.0.
Android SDK Build Tools 28.0.2 will be used.
To suppress this warning, remove "buildToolsVersion '26.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Remove Build Tools version and sync project
Affected Modules: mscV5PlusDemoWARNING: Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html
Affected Modules: mscV5PlusDemo第一个错误的意思是：minSdk版本不应该在android manifest文件中声明。您可以将版本从清单移动到构建中的defaultConfig。gradle文件。
那么我们就打开android manifest，找到minSdk，把他删除
第二个错误的意思是从构建版本中删除"buildToolsVersion ‘26.0.2’"，那么就删除他
第三个错误的意思是配置’compile’已过时，已被’implementation’和’api’取代。
然后同步一下，运行程序，发现不能跑起来，在build下回找到，如下图一段代码，
在build.gradle里面添加google(),如下图
同步一下，在运行，就可以装到手机上了，但是这里还有一点需要修改，就是把demo里面的APPID替换成自己注册的APPID，别忘了替换呀！！！
配置项目
讲demo中libs拷贝到自己的lib里
然后再将assets里面的文件全部导入到项目中
在线语音识别
首先添加权限
<!-- 连接网络权限，用于执行云端语音能力 --><uses-permission android:name="android.permission.INTERNET" /> <!-- 获取手机录音机使用权限，听写、识别、语义理解需要用到此权限 --><uses-permission android:name="android.permission.RECORD_AUDIO" /> <!-- 读取网络信息状态 --><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- 获取当前wifi状态 --><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_SETTINGS" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_CONTACTS" />
然后创建一个application，代码如下
public class SpeechApplication extends Application {@Overridepublic void onCreate() {// 5ef048e1 为在开放平台注册的APPID 注意没有空格，直接替换即可SpeechUtility.createUtility(SpeechApplication.this, "appid=5ef048e1");super.onCreate();}
}
下面是MainActivity里面的代码
public class MainActivity extends AppCompatActivity implements View.OnClickListener {private static final String TAG = "yaya";private SpeechRecognizer mIat;// 语音听写对象private RecognizerDialog mIatDialog;// 语音听写UI// 用HashMap存储听写结果private HashMap<String, String> mIatResults = new LinkedHashMap<String, String>();private SharedPreferences mSharedPreferences;//缓存private String mEngineType = SpeechConstant.TYPE_CLOUD;// 引擎类型private String language = "zh_cn";//识别语言private TextView tvResult;//识别结果private Button btnStart;//开始识别private String resultType = "json";//结果内容数据格式@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);tvResult = findViewById(R.id.tv_result);btnStart = findViewById(R.id.btn_start);btnStart.setOnClickListener(this);//实现点击监听initPermission();// 使用SpeechRecognizer对象，可根据回调消息自定义界面；mIat = SpeechRecognizer.createRecognizer(MainActivity.this, mInitListener);// 使用UI听写功能，请根据sdk文件目录下的notice.txt,放置布局文件和图片资源mIatDialog = new RecognizerDialog(MainActivity.this, mInitListener);mSharedPreferences = getSharedPreferences("ASR",Activity.MODE_PRIVATE);}@Overridepublic void onClick(View v) {if (null == mIat) {// 创建单例失败，与 21001 错误为同样原因，参考 http://bbs.xfyun.cn/forum.php?mod=viewthread&tid=9688showMsg("创建对象失败，请确认 libmsc.so 放置正确，且有调用 createUtility 进行初始化");return;}mIatResults.clear();//清除数据setParam();

语音唤醒

离线语音识别并更新本地词典命令词
在这里需要注意一下啊，命令词的更新词典是更新的槽，主要是为了方便想通讯录的录入，不支持大批量更新词典的，建议在设置命令词的时候就包含完整命令词即可。
代码如下
public class OfflineActivity extends AppCompatActivity {private final static String TAG = "yaya";private Toast mToast;// 语音识别对象private SpeechRecognizer mAsr;// 缓存
