 """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: 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. """
