Android Studio百度离线语音合成集成
-
首先注册百度开发者平台,创建应用
-
点击下一步,选择语音合成
-
点击下一步,选择下载语音合成SDK

-
下载完成之后输入包名,包名必须和程序的包名一致,包名可在清单文件中查看
-
到此创建应用完成,下面向项目中导入资源
1,打开下载的文件,将libs目录下的.jar文件拷贝到项目中的libs目录,然后添加库依赖(必须,必须,必须)
2,在src/main下创建jniLibs目录(L是大写),将下载文件中libs目录下的.so文件拷贝在jniLIbs目录下
3,在src/main下创建assets目录,将下载文件中的data目录下的文件拷贝到assets中,同步一下工程,完成之后目录如下图
12.png下面开始写代码
1,首先添加权限
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />```
#####2,初始化tts,将自己注册百度的key替换到MainActivity中声明的变量,key如下图,后面我贴上我的代码,大家参考
