``transport`` was not explicitly provided, the endpoint is

use the default regular endpoint) and "auto" (auto-switch to the
default mTLS endpoint if client certificate is present; this is
the default value).
2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable
is "true", then the ``client_cert_source`` property can be used
to provide a client certificate for mTLS transport. If
not provided, the default SSL client certificate will be used if
present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not
set, no client certificate will be used.

Args:
requests (Iterator[google.cloud.dialogflow_v2.types.StreamingDetectIntentRequest]):
The request object iterator. The top-level message sent by the client to the
[Sessions.StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]
method.
Multiple request messages should be sent in order:
1. The first message must contain
[session][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.session],
[query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input]
plus optionally
[query_params][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_params].
If the client wants to receive an audio response, it
should also contain
[output_audio_config][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.output_audio_config].
The message must not contain
[input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_audio].
2. If
[query_input][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.query_input]
was set to
[query_input.audio_config][google.cloud.dialogflow.v2.InputAudioConfig],
all subsequent messages must contain
[input_audio][google.cloud.dialogflow.v2.StreamingDetectIntentRequest.input_audio]
to continue with Speech recognition. If you decide to
rather detect an intent from text input after you
already started Speech recognition, please send a
message with
[query_input.text][google.cloud.dialogflow.v2.QueryInput.text].
However, note that:
- Dialogflow will bill you for the audio duration so
far.
- Dialogflow discards all Speech recognition results
in favor of the input text.
- Dialogflow will use the language code from the
first message.
After you sent all input, you must half-close or abort
the request stream.
retry (google.api_core.retry.Retry): Designation of what errors, if any,
should be retried.
timeout (float): The timeout for this request.
metadata (Sequence[Tuple[str, str]]): Strings which should be
sent along with the request as metadata.
Returns:
Iterable[google.cloud.dialogflow_v2.types.StreamingDetectIntentResponse]:
The top-level message returned from the
StreamingDetectIntent method.
Multiple response messages can be returned in order:
1. If the StreamingDetectIntentRequest.input_audio
field was set, the recognition_result field is
populated for one or more messages. See the
[StreamingRecognitionResult][google.cloud.dialogflow.v2.StreamingRecognitionResult]
message for details about the result message
sequence.
2. The next message contains response_id,
query_result and optionally webhook_status if a
WebHook was called.
