1.在线语音合成

 2.添加权限

G:\AndroidStudioProjects\AiVoikeApp\app\src\main\AndroidManifest.xml

    <uses-permission android:name="android.permission.INTERNET" />
    <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.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

支持level 28以上编译

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

3.导包

这个文件添加到

名字太长我改了名字

添加依赖库

对外所有用api

把这个文件夹也放进去

D:\Downloads\sdk_tts_baidu_speech_Baidu_TTS_Android_2.6.2.2.20200629_44818d4_online_1.1.4\app\src\main

4.初始化

G:\AndroidStudioProjects\AiVoikeApp\lib_voice\src\main\java\com\example\lib_voice\TTs\VoiceTTs.kt

package com.example.lib_voice.TTs

import android.content.Context
import android.util.Log
import com.baidu.tts.client.SpeechError
import com.baidu.tts.client.SpeechSynthesizer
import com.baidu.tts.client.SpeechSynthesizerListener
import com.baidu.tts.client.TtsMode
