语音识别Android应用程序 [英] Speech Recognition Android App

问题描述

我在做一个应用程序，从用户接受指令，并实时把它写。什么是对我来说，把最好的选择吗？第三方软件，如狮身人面像，或者我应该使用内置的（机器人语音识别）？

I'm making an app that takes commands from User and write it in real time. What would be the Best option for me to take? Third Party software like sphinx or should I use the built in (android speech recognition)?

其次，我希望它在实时写，就像我讲它开始写？

Secondly I want it to write in real time, like when I speak it starts writing?

推荐答案

您应该使用内置的Andr​​oid的语音识别。具体而言，您将需要操作的<一个href="http://developer.android.com/reference/android/speech/SpeechRecognizer.html">SpeechRecognier API，以便不存在弹出对话框。

You should use the built in Android Speech recognition. Specifically, you will need to operate the SpeechRecognier API so that there is no popup dialog box.

另外，不要指望SpeechRecognizer内返回任何<一href="http://developer.android.com/reference/android/speech/RecognitionListener.html#onPartialResults%28android.os.Bundle%29">onPartialResults().它很少做。

Also, do not expect SpeechRecognizer to return anything within onPartialResults(). It rarely does.

您可以尝试使用狮身人面像，但似乎其他开发商难以得到它在Android上运行。如果你希望你的应用程序在没有互联网连接运行说，狮身人面像将是你唯一的选择。

You could try to use Sphinx, but it seems other developers have difficulty getting it to run on Android. That said, sphinx will be your only option if you want your app to run without an internet connection.

下面是剪断$ C $的c您将需要使用SpeechRecognizer：

Here is a snipped of code you will need to use SpeechRecognizer:

 public void recognizeDirectly(Intent recognizerIntent)
    {
        // SpeechRecognizer requires EXTRA_CALLING_PACKAGE, so add if it's not
        // here
        if (!recognizerIntent.hasExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE))
        {
            recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                    "com.dummy");
        }
        SpeechRecognizer recognizer = getSpeechRecognizer();
        recognizer.startListening(recognizerIntent);
    }

    @Override
    public void onResults(Bundle results)
    {
        Log.d(TAG, "full results");
        receiveResults(results);
    }

    @Override
    public void onPartialResults(Bundle partialResults)
    {
        Log.d(TAG, "partial results");
        receiveResults(partialResults);
    }

    /**
     * common method to process any results bundle from {@link SpeechRecognizer}
     */
    private void receiveResults(Bundle results)
    {
        if ((results != null)
                && results.containsKey(SpeechRecognizer.RESULTS_RECOGNITION))
        {
            List<String> heard =
                    results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
            float[] scores =
                    results.getFloatArray(SpeechRecognizer.CONFIDENCE_SCORES);
            receiveWhatWasHeard(heard, scores);
        }
    }

    @Override
    public void onError(int errorCode)
    {
        recognitionFailure(errorCode);
    }

    /**
     * stop the speech recognizer
     */
    @Override
    protected void onPause()
    {
        if (getSpeechRecognizer() != null)
        {
            getSpeechRecognizer().stopListening();
            getSpeechRecognizer().cancel();
            getSpeechRecognizer().destroy();
        }
        super.onPause();
    }

    /**
     * lazy initialize the speech recognizer
     */
    private SpeechRecognizer getSpeechRecognizer()
    {
        if (recognizer == null)
        {
            recognizer = SpeechRecognizer.createSpeechRecognizer(this);
            recognizer.setRecognitionListener(this);
        }
        return recognizer;
    }

    // other unused methods from RecognitionListener...

    @Override
    public void onReadyForSpeech(Bundle params)
    {
        Log.d(TAG, "ready for speech " + params);
    }

    @Override
    public void onEndOfSpeech()
    {
    }
