使用默认 Google 提示对话框发送语音

触发语音到文本翻译

private void startListening() {

     //Intent to listen to user vocal input and return result in same activity
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    
   //Use a language model based on free-form speech recognition.
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());

    //Message to display in dialog box
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
            getString(R.string.speech_to_text_info));
    try {
        startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
    } catch (ActivityNotFoundException a) {
        Toast.makeText(getApplicationContext(),
                getString(R.string.speech_not_supported),
                Toast.LENGTH_SHORT).show();
    }
}

在 onActivityResult 中获得翻译结果

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
    case REQ_CODE_SPEECH_INPUT: {
        if (resultCode == RESULT_OK && null != data) {

            ArrayList<String> result = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            txtSpeechInput.setText(result.get(0));
        }
        break;
    }

    }
}
