Google Speech API example

# recognizer_instance.recognize_google(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.

# NOTE: this example requires PyAudio because it uses the Microphone class

	# for testing purposes, we're just using the default API key
	# to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
	# instead of `r.recognize_google(audio)`
