android 语音自动播报,Android语音播报的两种简单实现
a、两种方案
1、Android自带的语音播报(老版本手机Android6.0以下，不支持中文)
2、讯飞语音播报封装(直接用)
b、具体实现
一、Android自带的语音播报
查看手机是否支持中文语音播报，在测试的设备中打开‘设置’ -->找到 '语言和输入法'-->查看语音选项，是否支持中文，默认仅支持英文。
public class AndroidTTSActivity extends AppCompatActivity implements View.OnClickListener {
private TextToSpeech textToSpeech = null;//创建自带语音对象
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.android_tts_layout);
findViewById(R.id.btn0).setOnClickListener(this);
initTTS();
}
private void initTTS() {
//实例化自带语音对象
textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == textToSpeech.SUCCESS) {
// Toast.makeText(MainActivity.this,"成功输出语音",
// Toast.LENGTH_SHORT).show();
// Locale loc1=new Locale("us");
// Locale loc2=new Locale("china");
textToSpeech.setPitch(1.0f);//方法用来控制音调
textToSpeech.setSpeechRate(1.0f);//用来控制语速
//判断是否支持下面两种语言
int result1 = textToSpeech.setLanguage(Locale.US);
int result2 = textToSpeech.setLanguage(Locale.
SIMPLIFIED_CHINESE);
boolean a = (result1 == TextToSpeech.LANG_MISSING_DATA || result1 == TextToSpeech.LANG_NOT_SUPPORTED);
boolean b = (result2 == TextToSpeech.LANG_MISSING_DATA || result2 == TextToSpeech.LANG_NOT_SUPPORTED);
Log.i("zhh_tts", "US支持否？--》" + a +
"\nzh-CN支持否》--》" + b);
} else {
Toast.makeText(AndroidTTSActivity.this, "数据丢失或不支持", Toast.LENGTH_SHORT).show();
}
}
});
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btn0) {
startAuto("big sea");
}
}
private void startAuto(String data) {
// 设置音调，值越大声音越尖(女生)，值越小则变成男声,1.0是常规
textToSpeech.setPitch(1.0f);
// 设置语速
textToSpeech.setSpeechRate(0.3f);
textToSpeech.speak(data,//输入中文，若不支持的设备则不会读出来
TextToSpeech.QUEUE_FLUSH, null);
}
@Override
protected void onStop() {
super.onStop();
textToSpeech.stop(); // 不管是否正在朗读TTS都被打断
textToSpeech.shutdown(); // 关闭，释放资源
}
}
补充工具类
/**
* Created by RongGuang on 2014-11-21.
* 中文朗读
*/
public class ChineseToSpeech {
private TextToSpeech textToSpeech;
public ChineseToSpeech() {
this.textToSpeech = new TextToSpeech(Application.getContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = textToSpeech.setLanguage(Locale.CHINA);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
new CoolToast(Application.getContext()).show("不支持朗读功能");
}
}
}
});
}
public void speech(String text) {
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
public void destroy() {
if (textToSpeech != null) {
textToSpeech.stop();
textToSpeech.shutdown();
}
}
}
二、讯飞语音播报封装(直接用)
1.接入项目前准备：
1.申请APPID(步骤):
I.登录讯飞官网-->创建应用-->创建完成在''我的应用"中即可看见自己新建的项目&APPID-->
II.添加需要开通的服务：这里选择在线语音合成+sdk下载(so+jar文件),注意：so文件必须用你对应的项目的，用别人so文件，会导致与你的APPID不匹配,
2.使用说明+接入高频易发问题：
语音次数是有限制的，提高次数需要实名认证+上传项目引入的so文件必须是你项目所对应的不可多次初始化合成对象
3.接入项目(AndroidStudio):
I.相关sdk文件引入，如图(再次说明：so文件用的是你新建项目的so文件，不要用他人so)：
II.初始化语音播报(API>=23需要授权，所以先授权，再初始化，如下：)
public class StartActivity extends AppCompatActivity {
private List permissionList = null;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SystemClock.sleep(1000);//延时加载
requestPermissions();
}
private void openActivity(Class extends AppCompatActivity> clazz) {
initTTS();
startActivity(new Intent(this, clazz));
finish();
}
//权限申请
private void requestPermissions() {
// 版本判断。当手机系统大于 23 时，才有必要去判断权限是否获取
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
addListPermission();
boolean isGranted = false;//是否全部授权
// 权限是否已经 授权 GRANTED---授权 DINIED---拒绝
Iterator iterator = permissionList.iterator();
while (iterator.hasNext()) {
// 检查该权限是否已经获取
int granted = ContextCompat.checkSelfPermission(this, iterator.next());
if (granted == PackageManager.PERMISSION_GRANTED) {
iterator.remove();//已授权则remove
}
}
if (permissionList.size() > 0) {
// 如果没有授予该权限，就去提示用户请求
//将List转为数组
String[] permissions = permissionList.toArray(new String[permissionList.size()]);
// 开始提交请求权限
ActivityCompat.requestPermissions(this, permissions, 0x10);
} else {
Log.i("zhh", "权限已申请");
openActivity(MainActivity.class);
}
} else {
openActivity(MainActivity.class);
}
}
//初始化语音合成
private void initTTS() {
//讯飞语音播报平台
SpeechUtility.createUtility(this, "appid=");//=号后面写自己应用的APPID
Setting.setShowLog(true); //设置日志开关(默认为true)，设置成false时关闭语音云SDK日志打印
TTSUtils.getInstance().init(); //初始化工具类
}
/**
* 权限申请返回结果
*
* @param requestCode 请求码
* @param permissions 权限数组
* @param grantResults 申请结果数组，里面都是int类型的数
*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case 0x10:
if(grantResults.length>0&&ifGrantResult(grantResults)){
Toast.makeText(this, "同意权限申请", Toast.LENGTH_SHORT).show();
openActivity(MainActivity.class);
}else{
Toast.makeText(this, "权限被拒绝了", Toast.LENGTH_SHORT).show();
finish();
}
break;
default:
break;
}
}
private boolean ifGrantResult(int[] grants) {
boolean isGrant = true;
for (int grant : grants) {
if (grant == PackageManager.PERMISSION_DENIED) {
isGrant = false;
break;
}
}
return isGrant;
}
//敏感权限添加
private void addListPermission() {
if (null == permissionList) {
permissionList = new ArrayList<>();
permissionList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
permissionList.add(Manifest.permission.READ_PHONE_STATE);
permissionList.add(Manifest.permission.RECORD_AUDIO);
}
}
}
III.语音播报封装(部分代码)
public class TTSUtils implements InitListener, SynthesizerListener {
private static volatile TTSUtils instance = null;
private boolean isInitSuccess = false;
private SpeechSynthesizer mTts;
//单例模式
public static TTSUtils getInstance() {
if (instance == null) {
synchronized (TTSUtils.class) {
if (instance == null) {
instance = new TTSUtils();
}
}
}
return instance;
}
public TTSUtils() {
}
// 初始化合成对象
public void init() {
//判断进程是否已启动，初始化多次会报错
//个人遇到问题：极光推送引入后，不加该条件回报错
if (CourseUtils.resultProcess("com.zhanghai.ttsapp")) {
mTts = SpeechSynthesizer.createSynthesizer(App.getContext(), this);
// 清空参数
mTts.setParameter(SpeechConstant.PARAMS, null);
// 设置在线云端
mTts.setParameter(SpeechConstant.ENGINE_TYPE,
SpeechConstant.TYPE_CLOUD);
// 设置发音人--发音人选择--具体见values-string
mTts.setParameter(SpeechConstant.VOICE_NAME, "xiaoqi");
// 设置发音语速
mTts.setParameter(SpeechConstant.SPEED, "50");
// 设置音调
mTts.setParameter(SpeechConstant.PITCH, "50");
// 设置合成音量
mTts.setParameter(SpeechConstant.VOLUME, "100");
// 设置播放器音频流类型
mTts.setParameter(SpeechConstant.STREAM_TYPE, "3");
// 设置播放合成音频打断音乐播放，默认为true
mTts.setParameter(SpeechConstant.KEY_REQUEST_FOCUS, "true");
// 设置音频保存路径，需要申请WRITE_EXTERNAL_STORAGE权限，如不需保存注释该行代码
// mTts.setParameter(SpeechConstant.TTS_AUDIO_PATH,"./sdcard/iflytek.pcm");
Log.i("zhh", "--初始化成完成-");
}
}
//开始合成
public void speak(String msg) {
if (isInitSuccess) {
if (mTts.isSpeaking()) {
stop();
}
mTts.startSpeaking(msg, this);
} else {
init();
}
}
}
IV：调用实例
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private static final String TAG = MainActivity.class.getSimpleName();
private EditText et = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et = findViewById(R.id.et);
findViewById(R.id.btn0).setOnClickListener(this);
findViewById(R.id.btn1).setOnClickListener(this);
findViewById(R.id.btn2).setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn0:
TTSUtils.getInstance().speak("bigsea是大海");
break;
case R.id.btn1:
String msg = et.getText().toString();
TTSUtils.getInstance().speak(TextUtils.isEmpty(msg) ? "输入信息为空" : msg);
break;
case R.id.btn2:
startActivity(new Intent(this, AndroidTTSActivity.class));
break;
default:
break;
}
}
@Override
protected void onResume() {
//移动数据统计分析--不用可不用加入
FlowerCollector.onResume(MainActivity.this);
FlowerCollector.onPageStart(TAG);
super.onResume();
}
@Override
protected void onPause() {
//移动数据统计分析
FlowerCollector.onPageEnd(TAG);
FlowerCollector.onPause(MainActivity.this);
super.onPause();
}
@Override
protected void onDestroy() {
super.onDestroy();
TTSUtils.getInstance().release();//释放资源
}
}
完！！！
