Android TextToSpeech 行为不规则

Question

更新:经过一番挖掘，我设法在 Logcat 中找到了一些信息。见底部。

编辑 2:我现在从头开始创建了一个新 Activity 来减少这个问题。它仍然不能正常工作。这是代码:

public class MainActivity extends AppCompatActivity {
    private TextToSpeech textToSpeech;
    private boolean isInitialized = false;
    private MainActivity mainActivity;
    int ctr = 0;
    private String words[] = {"ord", "kula", "fotboll"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        mainActivity = this;

        textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS){
                    textToSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() {
                        @Override
                        public void onStart(String utteranceId) {
                            System.out.println("---onStart");
                        }

                        @Override
                        public void onDone(String utteranceId) {
                           System.out.println("-----onDone");
                        }

                        @Override
                        public void onError(String utteranceId) {
                            System.out.println("-----onError");
                        }

                        @Override
                        public void onError(String utteranceId, int errorCode){
                            onError(utteranceId);
                            System.out.println("Error with code: " + errorCode);
                        }
                    });
                    isInitialized = true;
                    Locale locale = new Locale("swe");
                    textToSpeech.setLanguage(locale);
                }
            }
        });
        FloatingActionButton fab = findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                if (isInitialized){
                    System.out.println(textToSpeech.getLanguage().getDisplayLanguage());
                    textToSpeech.speak(words[ctr], TextToSpeech.QUEUE_FLUSH, null, "SpeakTest");
                    ctr++;
                    ctr %= words.length;
                } else {
                    Snackbar.make(view, "Speaker not ready", Snackbar.LENGTH_LONG)
                            .setAction("Action", null).show();
                }
            }
        });

    }
}

非常令人惊讶的是，只说了“ord”和“fotboll”，却没有说“kula”。如果我将 words 更改为 {"kula", "kula", "kula"} 并尝试足够长的时间，它就会突然开始工作。据我了解文档应该使用标签 here .我试过 se、swe、sv，结果都一样。此外，命令 System.out.println(textToSpeech.getLanguage().getDisplayLanguage()); 给出正确的 svenska。

如果我更改为 en，它会一直有效。我也得到 System.out.println(textToSpeech.getLanguage().getDisplayLanguage());
= engelska 再次正确。

到底是怎么回事？

编辑:

根据 this，我添加了一个 UtteranceProgressListener , 方法

onError(String id) 已弃用，应替换为 onError(String id, int errorCode)。但是，我用 UtteranceProgressListener 扩展了我的类，它迫使我实现旧的 onError 方法。这总是被调用，所以出了点问题，但我不知道是什么。

这是因为另一个 onError(String id, int code) 从未被调用。

我已经更新了代码。

我有一个函数，它应该在调用该函数时用特定语言说出一个词。

直到几天前它在我的 Sony Compact XZ2 上运行良好，但现在它不正常。有时会说出这个词，有时不会。命令 textToSpeech.getEngines() 返回 com.google.android.tts

例如，对于瑞典语，在 setLanguage 中，我在创建 Locale 对象时尝试了“sv”和“sv-SV”。这没有帮助。

我刚刚注意到，当我多次按下调用 playWord(text) 的按钮时(> 40)，它会起作用，有时它会直接起作用。似乎是一些奇怪的延迟。

函数 speakText 是从我的 Fragment 中的这个函数调用的:

private void playWord(){
    if (text2Speech.isReady()) {
        text2Speech.checkSpeaking();
        text2Speech.setLanguage(getAcronym(mTraining.getCurrentSrc()));
        text2Speech.speakText(front);
    } else {
        Toast.makeText(getContext(),"Speaker not ready yet", Toast.LENGTH_SHORT).show();
    }
}

这是处理说话的类。我没有收到任何错误消息。扬声器工作时似乎是随机的。

public class Text2Speech extends UtteranceProgressListener {
    private Context mContext;
    private TextToSpeech textToSpeech;
    private boolean isReady = false;

        mContext = context;
        System.out.println("text2Speech created");

    }

    public boolean isReady(){

}

@Override
public void onDone(String utteranceId) {
    Log.e("DONE", "done speaking");
}

@Override
public void onError(String utteranceID){
    Log.e("Error", "Not infromative");
}

// This is not called!
@Override
public void onError(String utteranceId, int errorCode) {
    Log.e("Error", "Error speaking");
}
}

这是 Logcat 中的错误消息:

当我打开 WiFi 时，它可以正常工作。

推测:会不会是我没有使用 WiFi 时，语言丢失，没有下载？当我打开 WiFi 时，会下载语言？

对我来说这个错误:clx: RESOURCE_EXHAUSTED: Quota exceeded for quota metric... 看起来总是有网络请求，但在打开 WiFi 后，我可以在飞行模式下使用 TextToSpeach。

另一方面，我在飞行模式下尝试了俄语，但没有用。我在没有 WiFi 的情况下打开互联网，然后就可以了。再次打开 WiFi，然后俄语也能正常工作。至少这表明需要下载一些东西？

我想找出导致问题的原因以及解决方法，因为它是 Google Play 上的应用程序。 (虽然目前我旁边只有 0 个活跃用户...):)。

只是给出一些结论:这是一个 Android Framework Bug，已通过 Android 12 (API 31) 关闭。另请参阅我引用的 Bug Ticket:https://issuetracker.google.com/issues/138321382?pli=1
