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

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

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

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

(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

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

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

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

修改为:

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

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

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

(2)在APP的build.gradle中引入baiduspeechdialog

BaiduSpeechDemo【百度语音SDK集成】(基于v3.0.8.1)

(3)在Activity中调用
