Perform bi-directional speech recognition.

        This method allows you to receive results while sending audio;
        it is only available via. gRPC (not REST).

        .. warning::

            This method is EXPERIMENTAL. Its interface might change in the
            future.

        Example:
          >>> from google.cloud.speech_v1 import enums
          >>> from google.cloud.speech_v1 import SpeechClient
          >>> from google.cloud.speech_v1 import types

          >>> for element in client.streaming_recognize(config, requests):
          ...     # process element
          ...     pass

        Args:
            config (:class:`~.types.StreamingRecognitionConfig`): The
                configuration to use for the stream.
            requests (Iterable[:class:`~.types.StreamingRecognizeRequest`]):
                The input objects.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.

        Returns:
          Iterable[:class:`~.types.StreamingRecognizeResponse`]

        Raises:
          :exc:`google.gax.errors.GaxError` if the RPC is aborted.
          :exc:`ValueError` if the parameters are invalid.
