先到百度语音官网上查看集成指南
然后再去下载语音识别-离在线融合SDK(bd_speech_sdk_asr_v3.0.3.20170801_60da871.zip)
直接参考SDK中的ActivityMiniRecog类
这里,我就直接上代码了,我是在Android Studio 2.3.3 平台上编译的
1、app\build.gradle
apply plugin: 'com.android.application'android {compileSdkVersion 25buildToolsVersion "26.0.1"defaultConfig {applicationId "com.sky.baiduspeechdemo"minSdkVersion 15targetSdkVersion 25versionCode 1versionName "1.0"}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'}}
}dependencies {//compile fileTree(dir: 'libs', include: ['*.jar'])compile fileTree(exclude: '*.bak', dir: 'libs')compile 'com.android.support:appcompat-v7:25.3.1'compile 'com.google.code.gson:gson:2.8.2'
}
2、AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.sky.baiduspeechdemo"><!-- begin: baidu speech sdk 权限 --><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" /><!-- end: baidu speech sdk 权限 --><application
android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme"><!-- APP_ID API_KEY SECRET_KEY--><meta-data
android:name="com.baidu.speech.APP_ID"android:value="替换成你申请的AppID"/><meta-data
android:name="com.baidu.speech.API_KEY"android:value="替换成你申请的API Key" /><meta-data
android:name="com.baidu.speech.SECRET_KEY"android:value="替换成你申请的Secret Key" /><service
android:name="com.baidu.speech.VoiceRecognitionService"android:exported="false" /><activity android:name=".MainActivity"android:configChanges="orientation|keyboardHidden|screenLayout"android:screenOrientation="portrait"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application></manifest>
3、将SDK中的app/libs/bdasr_V3_20170801_60da871.jar 复制到您的项目的同名目录中。
4、将SDK中的app/src/main/jniLibs 下armeabi等5个目录,复制到您的项目的同名目录中。
5、activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/activity_main"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context="com.sky.baiduspeechdemo.MainActivity"><Button

</LinearLayout>
