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 `__ 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 `__. The profanity filter level can be adjusted with ``pfilter``: 0 - No filter, 1 - Only shows the first character and replaces the rest with asterisks. The default is level 0. 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. r0rjrX)rTr>rqoperation_timeoutrUr_) recognizerr3r)r*rrrVrWr(request_builderr=rY output_parserrrrrecognize_legacys  rw) r(rr)rSr*rr+r,r-r')r=r rirOr-r)NrRrFF)r3r r)rSr*rrrr,rVr!rWr!r(r)# __future__rrbtypingrrrr urllib.errorrr urllib.parser urllib.requestr r typing_extensionsr speech_recognition.audior speech_recognition.exceptionsrrrrr#r,rrEENDPOINTr'rTrUrqrwrrrrs<     I V
