``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).

is "true", then the ``client_cert_source`` property can be used

not provided, the default SSL client certificate will be used if
present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not

The request object iterator. The top-level message sent by the client to the
[Sessions.StreamingDetectIntent][google.cloud.dialogflow.cx.v3.Sessions.StreamingDetectIntent]
method.
Multiple request messages should be sent in order:
1. The first message must contain
[session][google.cloud.dialogflow.cx.v3.StreamingDetectIntentRequest.session],
[query_input][google.cloud.dialogflow.cx.v3.StreamingDetectIntentRequest.query_input]
plus optionally
[query_params][google.cloud.dialogflow.cx.v3.StreamingDetectIntentRequest.query_params].
If the client wants to receive an audio response, it
should also contain
[output_audio_config][google.cloud.dialogflow.cx.v3.StreamingDetectIntentRequest.output_audio_config].
2. If
[query_input][google.cloud.dialogflow.cx.v3.StreamingDetectIntentRequest.query_input]
was set to
[query_input.audio.config][google.cloud.dialogflow.cx.v3.AudioInput.config],
all subsequent messages must contain
[query_input.audio.audio][google.cloud.dialogflow.cx.v3.AudioInput.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.cx.v3.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

Returns:
Iterable[google.cloud.dialogflowcx_v3.types.StreamingDetectIntentResponse]:
The top-level message returned from the
[StreamingDetectIntent][google.cloud.dialogflow.cx.v3.Sessions.StreamingDetectIntent]
method.
Multiple response messages (N) can be returned in
order.
The first (N-1) responses set either the
recognition_result or detect_intent_response field,
depending on the request:
- If the
StreamingDetectIntentRequest.query_input.audio
field was set, and the
StreamingDetectIntentRequest.enable_partial_response
field was false, the recognition_result field is
populated for each of the (N-1) responses. See the
[StreamingRecognitionResult][google.cloud.dialogflow.cx.v3.StreamingRecognitionResult]
message for details about the result message
sequence.
- If the
StreamingDetectIntentRequest.enable_partial_response
field was true, the detect_intent_response field
is populated for each of the (N-1) responses,
where 1 <= N <= 4. These responses set the
[DetectIntentResponse.response_type][google.cloud.dialogflow.cx.v3.DetectIntentResponse.response_type]
field to PARTIAL.
For the final Nth response message, the
detect_intent_response is fully populated, and
[DetectIntentResponse.response_type][google.cloud.dialogflow.cx.v3.DetectIntentResponse.response_type]
is set to FINAL.
