Android的讲话 - 你怎么能在Android的阅读的文本？(Android speech -

你怎么能读取数据，也就是将简单的文本字符串中的Android语音（语音）？

是否有一个API，我可以做这样的事情：

TextToVoice speaker = new TextToVoice();
speaker.Speak("Hello World");

Answer 1:

在这里你去。在使用该库的教程最大的缺点是，它需要一个SD卡存储的声音。

Answer 2:

使用TTS比预期稍微有点复杂，但它很容易编写一个包装，让你你想要的API。

有一些你必须克服把它很好地工作的问题。

他们是：

始终将UtteranceId（或者OnUtteranceCompleted不会被调用）
设置OnUtteranceCompleted监听器（仅后的语音系统进行适当的初始化）


public class TextSpeakerDemo implements OnInitListener
 {
    private TextToSpeech tts;
    private Activity activity;

    private static HashMap DUMMY_PARAMS = new HashMap();
    static 
    {
        DUMMY_PARAMS.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "theUtId");
    }
    private ReentrantLock waitForInitLock = new ReentrantLock();

    public TextSpeakerDemo(Activity parentActivity)
    {
        activity = parentActivity;
        tts = new TextToSpeech(activity, this);       
        //don't do speak until initing
        waitForInitLock.lock();
    }

    public void onInit(int version)
    {        //unlock it so that speech will happen
        waitForInitLock.unlock();
    }  

    public void say(WhatToSay say)
    {
        say(say.toString());
    }

    public void say(String say)
    {
        tts.speak(say, TextToSpeech.QUEUE_FLUSH, null);
    }

    public void say(String say, OnUtteranceCompletedListener whenTextDone)
    {
        if (waitForInitLock.isLocked())
        {
            try
            {
                waitForInitLock.tryLock(180, TimeUnit.SECONDS);
            }
            catch (InterruptedException e)
            {
                Log.e("speaker", "interruped");
            }
            //unlock it here so that it is never locked again
            waitForInitLock.unlock();
        }

        int result = tts.setOnUtteranceCompletedListener(whenTextDone);
        if (result == TextToSpeech.ERROR)
        {
            Log.e("speaker", "failed to add utterance listener");
        }
        //note: here pass in the dummy params so onUtteranceCompleted gets called
        tts.speak(say, TextToSpeech.QUEUE_FLUSH, DUMMY_PARAMS);
    }

    /**
     * make sure to call this at the end
     */
    public void done()
    {
        tts.shutdown();
    }
}

Answer 3:

TTS用法的良好的工作的例子可以在“临Android的2书”中找到。看看他们的源代码，第15章。

Answer 4:

有第三方文本到语音引擎。有传言说，甜甜圈包含一个文本到语音转换引擎，暗示这将是Android的未来版本。除此之外，虽然没有什么内置的Android文本到语音转换。

Answer 5:

甜甜圈有这样的：看到android.speech.tts包。
