软件杯语音
一、Android自带的语音播报
1.查看是否支持中文,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.
使用如下:
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 } }
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<String> 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<String> 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 } }
