    intent.putExtra（RecognizerIntent.EXTRA_LANGUAGE_MODEL，
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM）;
    intent.putExtra（RecognizerIntent.EXTRA_PROMPT，语音识别演示）;
    startActivityForResult（意向，VOICE_RECOGNITION_REQUEST_ code）;
}@覆盖
保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    如果（要求code == VOICE_RECOGNITION_REQUEST_ code和;＆安培;结果code == RESULT_OK）{
        //装满字符串列表视图中的识别器认为它可能已经听说
        ArrayList的＆LT;串GT;比赛= data.getStringArrayListExtra（
                RecognizerIntent.EXTRA_RESULTS）;
        mList.setAdapter（新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_list_item_1，

您无法通过Android的语音识别API将音频文件（如Android版V4.3的）。

The following code can recognise voice using Google voice search when I speak to microphone.

How can I pass an audio file as input instead of microphone to Google search voice?

private void startVoiceRecognitionActivity() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
    startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}



@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
        // Fill the list view with the strings the recognizer thought it could have heard
        ArrayList<String> matches = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);
        mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
                matches));
    }

    super.onActivityResult(requestCode, resultCode, data);
}

解决方案

You cannot pass an audio file through the Android speech recognition API (as of Android v4.3).
