Asynchronous Recognition
------------------------

The :meth:`~google.cloud.speech.Client.async_recognize` sends audio data to the
Speech API and initiates a Long Running Operation. Using this operation, you
can periodically poll for recognition results. Use asynchronous requests for
audio data of any duration up to 80 minutes.
