[SOLVED] How to continuously to do speech recognition while outputting the recognized word as soon as possible

I am working on a project that involves speech recognition using the SpeechRecognition module. One thing I want to do to improve my speech recognition is to be able to output the words that have been recognized as soon as possible. I want it to be similar to whenever you speak into Google Translate, as soon as you say a word it outputs it on the screen to let you know that you have said it.

Some of the things I have tried are to have an array that stores separate audio recordings and have speech recognition iterate through the array recognizing each audio recording and then outputting that. This did not work because different words take different times to say.

I looked further into the Google API for speech recognition given to me by the SpeechRecognition module and wanted to see how I could adjust the actual library by adding print statements in some places to achieve the goal. I did not know where to put, as I am a beginner in speech recognition and that I do not know much about the Google Speech Recognition API.

Here is the google api code, it accesses the cloud to do sr.

def recognize_google(self, audio_data, key=None, language="en-US", show_all=False):
        """
        Performs speech recognition on ``audio_data`` (an ``AudioData`` instance), using the Google Speech Recognition API.

        The Google Speech Recognition API key is specified by ``key``. If not specified, it uses a generic key that works out of the box. This should generally be used for personal or testing purposes only, as it **may be revoked by Google at any time**.

        To obtain your own API key, simply following the steps on the `API Keys <http://www.chromium.org/developers/how-tos/api-keys>`__ page at the Chromium Developers site. In the Google Developers Console, Google Speech Recognition is listed as "Speech API".

        The recognition language is determined by ``language``, an RFC5646 language tag like ``"en-US"`` (US English) or ``"fr-FR"`` (International French), defaulting to US English. A list of supported language tags can be found in this `StackOverflow answer <http://stackoverflow.com/a/14302134>`__.

        Returns the most likely transcription if ``show_all`` is false (the default). Otherwise, returns the raw API response as a JSON dictionary.

        Raises a ``speech_recognition.UnknownValueError`` exception if the speech is unintelligible. Raises a ``speech_recognition.RequestError`` exception if the speech recognition operation failed, if the key isn't valid, or if there is no internet connection.

Here is my base code (the things I previously tried are not shown here): It is able to successfully do speech recognition.

r = sr.Recognizer()
m = sr.Microphone(); 

r = sr.Recognizer()
on = True 
while on :
    with sr.Microphone() as source:
        audio = r.listen(source)

        try:
            text = r.recognize_google(audio)
            print("You said: {}".format(text))
        except:
            print("Sorry, we did not recognize your voice")

The final method you should know is the recording function to make audio files or objects:

def listen(self, source, timeout=None, phrase_time_limit=None, snowboy_configuration=None):
        """
        Records a single phrase from ``source`` (an ``AudioSource`` instance) into an ``AudioData`` instance, which it returns.

        This is done by waiting until the audio has an energy above ``recognizer_instance.energy_threshold`` (the user has started speaking), and then recording until it encounters ``recognizer_instance.pause_threshold`` seconds of non-speaking or there is no more audio input. The ending silence is not included.

        The ``timeout`` parameter is the maximum number of seconds that this will wait for a phrase to start before giving up and throwing an ``speech_recognition.WaitTimeoutError`` exception. If ``timeout`` is ``None``, there will be no wait timeout.

        The ``phrase_time_limit`` parameter is the maximum number of seconds that this will allow a phrase to continue before stopping and returning the part of the phrase processed before the time limit was reached. The resulting audio will be the phrase cut off at the time limit. If ``phrase_timeout`` is ``None``, there will be no phrase time limit.

        The ``snowboy_configuration`` parameter allows integration with `Snowboy <https://snowboy.kitt.ai/>`__, an offline, high-accuracy, power-efficient hotword recognition engine. When used, this function will pause until Snowboy detects a hotword, after which it will unpause. This parameter should either be ``None`` to turn off Snowboy support, or a tuple of the form ``(SNOWBOY_LOCATION, LIST_OF_HOT_WORD_FILES)``, where ``SNOWBOY_LOCATION`` is the path to the Snowboy root directory, and ``LIST_OF_HOT_WORD_FILES`` is a list of paths to Snowboy hotword configuration files (`*.pmdl` or `*.umdl` format).

        This operation will always complete within ``timeout + phrase_timeout`` seconds if both are numbers, either by returning the audio data, or by raising a ``speech_recognition.WaitTimeoutError`` exception.

I would like to achieve software that is able to take the current code and implement in such a way it outputs the recognized word as soon as possible. It would be similar to when you speak in Google Translate.
