# Unity_XunFeiSDK 使用Unity5.x和AndroidStudio，为安卓添加语音识别。版权声明：本文为孙思谋原创文章，未经允许不得转载如果能找回微博账号，我会把它分享到微博上，再此先做备份。网上大多是unity5.0以下和eclipse的教学。走了不少弯路。现在特地将在AndroidStudio和Unity5.0+环境下讯飞SDK接入的放法分享一下。首先获取讯飞SDK的方法就不再多说了，网上随意搜一下就有很多。获取APPID并且下载完SDK后，我们开始以下步骤： 1、AS新建工程，EmptyActivity，这样省了在AndroidManifest添加权限的步骤，同时可以删除layout文件夹中的布局文件，因为导入到unity中用不到。 2、File-New-New Module，新建AndroidLibrary，命名随意，作者在这里命名为speechrecognizer2,。 3、将SDK文件夹中的MSC.jar考到libs文件夹下。在main文件夹下新建文件夹jinLibs，将SDK中的so文件考进来，如图： Image 4、在Unity安装目录下找到class.jar文件。同样，考到libs文件夹下。路径： \Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes 5、此时需要在工程中关联jar。File-Project Structure。左侧选中步骤二中新建的Library。点击右方加号，选择Files dependency。将步骤3、4中加入的jar包关联到module。如图： Image 6、环境搭建完成，我们可以开心的写代码了。 MainActivity中的代码和网上其他的方法大同小异，直接上源码： package com.ssm.ssm.speechrecognizer; import android.os.Bundle; import android.util.Log; import android.widget.Toast; import com.iflytek.cloud.InitListener; import com.iflytek.cloud.RecognizerListener; import com.iflytek.cloud.RecognizerResult; import com.iflytek.cloud.SpeechConstant; import com.iflytek.cloud.SpeechError; import com.iflytek.cloud.SpeechUtility; import com.iflytek.cloud.SpeechRecognizer; import com.unity3d.player.UnityPlayer; import com.unity3d.player.UnityPlayerActivity; import org.json.JSONArray; import org.json.JSONObject; import org.json.JSONTokener; public class MainActivity extends UnityPlayerActivity { public SpeechRecognizer speechRecognizer; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //注意这里的appid为讯飞官网上注册获得的appid SpeechUtility.createUtility(getApplicationContext(),"appid=XXXXXXXXX"); initRecognizer(); } //初始化 private void initRecognizer(){ speechRecognizer = SpeechRecognizer.createRecognizer(getApplicationContext(),mInitListener); } public InitListener mInitListener = new InitListener() { @Override public void onInit(int i) { UnityPlayer.UnitySendMessage("Manager", "Result", "init success!"); } }; //开始听写 public void startSpeechListener(){ UnityPlayer.UnitySendMessage("Manager", "Result", "startListening"); speechRecognizer.setParameter(SpeechConstant.DOMAIN, "iat"); speechRecognizer.setParameter(SpeechConstant.LANGUAGE, "zh_cn"); speechRecognizer.setParameter(SpeechConstant.ACCENT, "mandarin"); speechRecognizer.startListening(mRecognizerListener); } public RecognizerListener mRecognizerListener = new RecognizerListener(){ @Override public void onBeginOfSpeech() { // TODO Auto-generated method stub //UnityPlayer.UnitySendMessage("Manager", "Result", "onBeginOfSpeech"); } @Override public void onEndOfSpeech() { // TODO Auto-generated method stub //UnityPlayer.UnitySendMessage("Manager", "Result", "onEndOfSpeech"); } @Override public void onError(SpeechError arg0) { // TODO Auto-generated method stub //UnityPlayer.UnitySendMessage("Manager", "Result", "onError"); } @Override public void onEvent(int arg0, int arg1, int arg2, Bundle arg3) { // TODO Auto-generated method stub //UnityPlayer.UnitySendMessage("Manager", "Result", "onEvent"); } @Override public void onResult(RecognizerResult recognizerResult, boolean isLast) { //UnityPlayer.UnitySendMessage("Manager", "Result", "listener"); printResult(recognizerResult); } @Override public void onVolumeChanged(int arg0, byte[] arg1) { //UnityPlayer.UnitySendMessage("Manager", "Result", "onVolumeChanged"); // TODO Auto-generated method stub } }; //解析 private void printResult(RecognizerResult results) { String json = results.getResultString(); StringBuffer ret = new StringBuffer(); try { JSONTokener tokener = new JSONTokener(json); JSONObject joResult = new JSONObject(tokener); JSONArray words = joResult.getJSONArray("ws"); for (int i = 0; i < words.length(); i++) { // 转写结果词，默认使用第一个结果 JSONArray items = words.getJSONObject(i).getJSONArray("cw"); JSONObject obj = items.getJSONObject(0); ret.append(obj.getString("w")); } } catch (Exception e) { e.printStackTrace(); } //将解析结果“"result:" + ret.toString()”发送至“Manager”这个GameObject，中的“Result”函数 UnityPlayer.UnitySendMessage("Manager", "Result", "result:" + ret.toString()); } } AndroidManifest中添加权限，同样，和其他教程大同小异，源码：

此时，作为AS，为了导出jar，需要在build.gradle中添加以下两段代码： task makeJar(type: Copy) { delete 'build/libs/speechrecognizer.jar' from('build/intermediates/bundles/release/') into('build/libs/') include('classes.jar') rename ('classes.jar', 'speechrecognizer.jar') } makeJar.dependsOn(build) // 在终端执行生成JAR包 // gradlew makeJar dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile files('libs/classes.jar') } build.gradle源码为： apply plugin: 'com.android.library' android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { minSdkVersion 15 targetSdkVersion 24 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:24.2.1' testCompile 'junit:junit:4.12' compile files('libs/Msc.jar') compile files('libs/classes.jar') } task makeJar(type: Copy) { delete 'build/libs/speechrecognizer.jar' from('build/intermediates/bundles/release/') into('build/libs/') include('classes.jar') rename ('classes.jar', 'speechrecognizer.jar') } makeJar.dependsOn(build) // 在终端执行生成JAR包 // gradlew makeJar dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile files('libs/classes.jar') } 7、至此，架包已经编写完成。现在导出jar。在Terminal中输入 gradlew makejar。如图： Image 8、等待完成后即可在libs下看到jar文件： Image 8、新建Unity项目，在Asset文件夹下新建如下结构：Image 9、如步骤8，在bin文件夹下拷贝AS导出的jar。libs文件夹下拷贝SDK中的MSC.jar，和os文件，注意，安卓5.0以上系统需要armeabi-v7a，不然会出现21002的错误。最后在Android文件夹下拷贝AndroidManifest文件。 10、至此，已经成功的将讯飞导入至Unity中，在Unity中编写代码调用即可。源码： public class XunFeiTest : MonoBehaviour { private string showResult = ""; void Start () { } void OnGUI () { if (GUILayout.Button ("startRecognizer", GUILayout.Height (100))) { AndroidJavaClass jc = new AndroidJavaClass ("com.unity3d.player.UnityPlayer"); AndroidJavaObject jo = jc.GetStatic ("currentActivity"); jo.Call ("startSpeechListener"); } GUILayout.TextArea (show + showResult, GUILayout.Width (200)); } public void Result (string recognizerResult) { showResult += recognizerResult; } } 11、demo编写完成，导出apk试一下吧！注意尽量使用真机测试。作者在用AS测试讯飞听写功能时就遇到模拟器无法获得权限的坑。
