Question

我正在尝试创建一个使用Speech来发送文本和Text to speech的应用程序所以这个程序的算法是：
1 - 当用户运行该程序时，它将调用语音识别 2 - 在收到用户的输入后，程序将重复用户所说的相同单词。

这是我的代码：

 public class MainActivity extends Activity implements TextToSpeech.OnInitListener, OnClickListener {

protected static final int REQUEST_OK = 1234;
String userSay;
TextView text1;
private TextToSpeech tts;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

    findViewById(R.id.button1).setOnClickListener(this);
    text1 = (TextView) findViewById(R.id.text1);
    tts=new TextToSpeech(this, this);
}

@Override
public void onDestroy() {
    // Don't forget to shutdown tts!
    if (tts != null) {
        tts.stop();
        tts.shutdown();
    }
    super.onDestroy();
}

@Override
   public void onPause(){
      if(tts !=null){
         tts.stop();
         tts.shutdown();
      }
      super.onPause();
   }

@Override
public void onInit(int status) {

    if (status == TextToSpeech.SUCCESS) {
        Log.e("TTS", "Initilization Success!");        
        int result = tts.setLanguage(Locale.US);

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "This Language is not supported");
        } else {
            String anyThing = " ";
            speakIt(anyThing);
        }
        return;
    } else {
        Log.e("TTS", "Initilization Failed!");
    }

}

private void speakIt(String someThing) {
    Log.e("something: ", someThing);
        tts.speak(someThing, TextToSpeech.QUEUE_ADD, null);
        Log.e("TTS", "called");
}

@Override
public void onClick(View v) {
    //Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
     //i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
    text1.setText(" ");
    Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    i.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, this.getPackageName());
    i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
    i.putExtra(RecognizerIntent.EXTRA_PROMPT, "I'm listen to you...");
     try {
         startActivityForResult(i, REQUEST_OK);
     } catch (Exception e) {
         Toast.makeText(this, "Error initializing speech to text engine.", Toast.LENGTH_LONG).show();
     }

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode==REQUEST_OK  && resultCode==-1) {
        ArrayList<String> thingsYouSaid = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

        userSay = thingsYouSaid.get(0);

    }
    try {
        String FinalValue = getDataMethod(hasil);
        text1.setText(FinalValue);
        Log.v("Status OK: ", FinalValue);
        speakIt(FinalValue);
        Log.v("speakIt: ", "called");
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    super.onActivityResult(requestCode, resultCode, data);
}

private String getDataMethod(String num) throws IllegalStateException, IOException {
    num = "You say, " + num;
    return num;
}


   }

但应用程序不会说什么。在logcat中我得到一个错误，上面写着：
TextToSpeech（10335）：说话失败：未绑定到TTS

在我提出这个申请之前，我是在不同的部分制作的：文本到语音，语音到文本这两个应用程序都正常运行我不知道为什么会出现这种错误任何人都可以帮助我吗？

Answer 1

一个问题是你在打电话：

speakIt(FinalValue);

内

onActivityResult(

在onPause中，执行：

if(tts !=null){
    tts.stop();
    tts.shutdown();
}

所以，一旦你打开你的子活动，onPause被调用并且tts被关闭，返回你使用这样的被破坏的tts这是错误的并且可能导致这样的行为。

您可以将代码从onPause移动到onStop，将初始代码移动到onStart。在onActivityResult中设置一些类实例变量，其数据在onInit内部说话。

说话失败：没有绑定到TTS引擎
