我正在从事语音识别工作，需要一些示例程序。

谁能指导我？

让我剪切并粘贴一些内容，向您展示您需要的代码。

编辑:您还可以从 this project 下载方便的抽象类.

您将需要此 Intent (按您认为合适的方式进行参数化):

public Intent getRecognizeIntent(String promptToUse, int maxResultsToReturn)
{
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, maxResultsToReturn);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, promptToUse);
    return intent;
}

然后您需要像这样将您的 Intent 发送到语音识别 Activity ，

public void gatherSpeech(String prompt)
{
    Intent recognizeIntent = getRecognizeIntent(prompt);
    try
    {
        startActivityForResult(recognizeIntent, SpeechGatherer.VOICE_RECOGNITION_REQUEST_CODE);
    }
    catch (ActivityNotFoundException actNotFound)
    {
        Log.w(D_LOG, "did not find the speech activity, not doing it");
    }
}

然后您需要让您的 Activity 处理语音结果:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    Log.d("Speech", "GOT SPEECH RESULT " + resultCode + " req: "
        + requestCode);
    if (requestCode == SpeechGatherer.VOICE_RECOGNITION_REQUEST_CODE)
    {
        if (resultCode == RESULT_OK)
        {
            ArrayList<String> matches = data
                            .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            Log.d(D_LOG, "matches: ");
            for (String match : matches)
            {
                Log.d(D_LOG, match);
            }
        }
    }
}
