文本到语音转换工作不正常 [英] Text to Speech not working as expected

问题描述

我跟几个教程，但我遇到了同样的问题。首先，这里是我的简单的code：

I have followed several tutorials, but I am experiencing the same problem. First, here is my simple code:

import java.util.Locale;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;

public class AchievementsActivity extends Activity implements OnInitListener {

    TextToSpeech reader;
    Locale canada;
    boolean readerInit = false;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);


        canada = Locale.ENGLISH;
        reader = new TextToSpeech(this, this);

        //speak();

        //      while (reader.isSpeaking()) {} //waiting for reader to finish speaking

    }

    @Override
    public void onStart()   {
        super.onStart();
        //speak();

    }

    @Override
    public void onInit(int status) {

        if (status == TextToSpeech.SUCCESS) {
            reader.setLanguage(canada);
            reader.setPitch(0.9f);
            Log.e("Init", "Success");
            readerInit = true;
            speak();
        }

        else
            System.out.println("Something went wrong.");
    }

    public void speak() {
        reader.speak("You currently have no achievements.", TextToSpeech.QUEUE_FLUSH, null);
    }
}

现在，请注意的onCreate第一讲（）这是我注释掉，而第二次在 ONSTART（）我也注释掉。根据我收到的LogCat中这样做的原因是显而易见的。出于某种原因，他们的阅读器的初始化之前被称为已完成。所以我这个工作的权利的唯一途径是通过将说话（）初始化后立即功能是一定要完成自己的方法中。

Now, notice the first speak in onCreate() which I have commented out, and the second in onStart() which I have also commented out. The reason for this is obvious based on what I receive in LogCat. For some reason, they are called before the initialization of the reader is complete. So the only way I have this working right is by placing the speak() function immediately after the initialization is sure to complete inside its own method.

所以我在想，如果有任何的方式来等待初始化完成，然后运行说话（）在的onCreate 或 ONSTART（）。

So I was wondering if there is any way to wait for the initialization to complete, and then run speak() in onCreate or onStart().

推荐答案

请看一看，以<一href="http://www.jameselsey.co.uk/blogs/techblog/android-a-really-easy-tutorial-on-how-to-use-text-to-speech-tts-and-how-you-can-enter-text-and-have-it-spoken/"相对=nofollow>本教程。
基本上，它迫使的onCreate（）方法，在初始。

please take a look to this tutorial.
Basically, it forces the init during the onCreate() method.

// Fire off an intent to check if a TTS engine is installed
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);

然后，您就可以在演讲一开始你想要的任何文本（与从用户的任何交互）。当然，说话会工作。

Then, you will be able to speech any text you want at the start (with out any interaction from the user). And of course, speak will work.

HTH!
