BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)
版权声明:本文为HaiyuKing原创文章,转载请注明出处!
前言
上一篇集成的是V3.0.7.3版本的SDK《BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.7.3)》,这次发现官网的SDK进行了升级,感觉有必要进行重新集成。
1、修复了APP同时集成多个SDK,不能同时使用的问题;——所以需要使用新sdk的jar文件;
2、既然官网也使用了module方式;——那么就不需要自己创建module了,直接在官网的core这个module中优化;
3、修复长语音无结束回调;——增加长语音结束回调的监听;
本Demo中使用的appkey已失效,请自行创建应用,使用新的appkey。
效果图
和《BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.7.3)》类似,这里就不单独截图了。
代码分析
普通话 search搜索模型:参考SpeechBottomSheetDialog.java类
普通话 input输入法模型,适用于长句及长语音,有逗号分割,无语义:参考SpeechLongBottomSheetDialog.java类
注意:关于语音识别状态维护,API调用的代码,是自己根据官网demo的理解进行整理的,可能有所偏颇,仅供参考。【希望官网demo可以添加百度APP的语音对话框效果就好了】
使用步骤
一、项目组织结构图
注意事项:
1、 导入类文件后需要change包名以及重新import R文件路径
2、 Values目录下的文件(strings.xml、dimens.xml、colors.xml等),如果项目中存在,则复制里面的内容,不要整个覆盖
二、导入步骤
(1)在项目中导入官网demo中的core这个module,同时修改名称,修改为baiduspeech
(2)修改baiduspeech的AndroidManifest.xml(修改官网申请的应用信息)
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="test2.baidu.com.baseasr"> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <application> <meta-data android:name="com.baidu.speech.APP_ID" android:value="11588936"/> <meta-data android:name="com.baidu.speech.API_KEY" android:value="XRF3IOf2tNGePzlv47cBnvF3"/> <meta-data android:name="com.baidu.speech.SECRET_KEY" android:value="diC8lQ7XDcGBKQ6FzCpvnan54F5CnMZI"/> </application> </manifest>
(3)修改MessageStatusRecogListener.java文件【根据实际情况进行修改】
package com.baidu.aip.asrwakeup3.core.recog.listener; import android.os.Handler; import android.os.Message; import android.util.Log; import com.baidu.aip.asrwakeup3.core.recog.RecogResult; import com.baidu.speech.asr.SpeechConstant; /** * Created by fujiayi on 2017/6/16. */ public class MessageStatusRecogListener extends StatusRecogListener { private Handler handler; private long speechEndTime = 0; private boolean needTime = true; private static final String TAG = "MesStatusRecogListener"; public MessageStatusRecogListener(Handler handler) { this.handler = handler; } @Override public void onAsrReady() { super.onAsrReady(); speechEndTime = 0; sendStatusMessage(SpeechConstant.CALLBACK_EVENT_WAKEUP_READY, "引擎就绪,可以开始说话。"); } @Override public void onAsrBegin() { super.onAsrBegin(); sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_BEGIN, "检测到用户说话"); } @Override public void onAsrEnd() { super.onAsrEnd(); speechEndTime = System.currentTimeMillis(); sendMessage("【asr.end事件】检测到用户说话结束"); } @Override public void onAsrPartialResult(String[] results, RecogResult recogResult) { sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL, "临时识别结果,结果是“" + results[0] + "”;原始json:" + recogResult.getOrigalJson()); super.onAsrPartialResult(results, recogResult); } @Override public void onAsrFinalResult(String[] results, RecogResult recogResult) { super.onAsrFinalResult(results, recogResult); //String message = "识别结束,结果是”" + results[0] + "”";//why 实际中可以去掉,不需要 String message = recogResult.getOrigalJson();//{"results_recognition":["什么什么"],"origin_result":{"corpus_no":6522034498058113957,"err_no":0,"result":{"word":["什么什么"]},"sn":"bfa8b286-ab0e-4f86-9209-1d36d38b1224","voice_energy":16191.7705078125},"error":0,"best_result":"什么什么","result_type":"final_result"} sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL, message + ";原始json:" + recogResult.getOrigalJson()); if (speechEndTime > 0) { long currentTime = System.currentTimeMillis(); long diffTime = currentTime - speechEndTime; //message += ";说话结束到识别结束耗时【" + diffTime + "ms】";// why 实际中可以去掉,不需要 } speechEndTime = 0; sendMessage(message, status, true); } @Override public void onAsrFinishError(int errorCode, int subErrorCode, String descMessage, RecogResult recogResult) { super.onAsrFinishError(errorCode, subErrorCode, descMessage, recogResult); //String message = "识别错误, 错误码:" + errorCode + " ," + subErrorCode + " ; " + descMessage;// why 实际中可以去掉,不需要 String message = recogResult.getOrigalJson();//{"origin_result":{"sn":"","error":7,"desc":"No recognition result match","sub_error":7001},"error":7,"desc":"No recognition result match","sub_error":7001} sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL, message); if (speechEndTime > 0) { long diffTime = System.currentTimeMillis() - speechEndTime; //message += "。说话结束到识别结束耗时【" + diffTime + "ms】";// why实际中可以去掉,不需要 } speechEndTime = 0; sendMessage(message, status, true); speechEndTime = 0; } @Override public void onAsrOnlineNluResult(String nluResult) { super.onAsrOnlineNluResult(nluResult); if (!nluResult.isEmpty()) { sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL, "原始语义识别结果json:" + nluResult); } } @Override public void onAsrFinish(RecogResult recogResult) { super.onAsrFinish(recogResult); sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_FINISH, "识别一段话结束。如果是长语音的情况会继续识别下段话。"); } /** * 长语音识别结束 */ @Override public void onAsrLongFinish() { super.onAsrLongFinish(); sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_LONG_SPEECH, "长语音识别结束。"); } /** * 使用离线命令词时,有该回调说明离线语法资源加载成功 */ @Override public void onOfflineLoaded() { sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_LOADED, "离线资源加载成功。没有此回调可能离线语法功能不能使用。"); } /** * 使用离线命令词时,有该回调说明离线语法资源加载成功 */ @Override public void onOfflineUnLoaded() { sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_UNLOADED, "离线资源卸载成功。"); } @Override public void onAsrExit() { super.onAsrExit(); sendStatusMessage(SpeechConstant.CALLBACK_EVENT_ASR_EXIT, "识别引擎结束并空闲中"); } private void sendStatusMessage(String eventName, String message) { message = "[" + eventName + "]" + message; sendMessage(message, status); } private void sendMessage(String message) { sendMessage(message, WHAT_MESSAGE_STATUS); } private void sendMessage(String message, int what) { sendMessage(message, what, false); } private void sendMessage(String message, int what, boolean highlight) { if (needTime && what != STATUS_FINISHED) { message += " ;time=" + System.currentTimeMillis(); } if (handler == null) { Log.i(TAG, message); return; } Message msg = Message.obtain(); msg.what = what; msg.arg1 = status; if (highlight) { msg.arg2 = 1; } msg.obj = message + "\n"; handler.sendMessage(msg); } }
至此,百度语音SDK集成到baiduspeech中了,下一步就是创建UI对话框(建议再单独创建一个新的module)。
(4)新建baiduspeechdialog这个module
1、在baiduspeechdialog的build.gradle中引用recyclerview【版本号和项目的appcompat保持一致】【因为demo中用到了】【注意:还需要导入baiduspeech这个module】
apply plugin: 'com.android.library'
android {
compileSdkVersion 27
defaultConfig {
minSdkVersion 16
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
//RecyclerView
compile 'com.android.support:recyclerview-v7:27.1.1'
//baiduspeech
implementation project(':baiduspeech')
}
2、对话框类、列表适配器类、布局文件xml文件、图片资源、动画style样式等复制到baiduspeechdialog中【参考《BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.7.3)》】
3、SpeechBottomSheetDialog.java和SpeechLongBottomSheetDialog.java在V3.0.7.3版本和V3.0.8.1版本的区别
3.1、需要将Logger修改为MyLogger
修改为:
三、使用方法
(1)因为需要使用到运行时权限,所以参考《Android6.0运行时权限(基于RxPermission开源库)》在APP的build.gradle中引入第三方库
(2)在APP的build.gradle中引入baiduspeechdialog
(3)在Activity中调用
