Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class StreamingAnalyzeContentRequest.

The top-level message sent by the client to the Participants.StreamingAnalyzeContent method.

Multiple request messages should be sent in order:

1. The first message must contain participant, config and optionally query_params. If you want to receive an audio response, it should also contain reply_audio_config. The message must not contain input.
2. If config in the first message was set to audio_config, all subsequent messages must contain input_audio to continue with Speech recognition. However, note that:
   • Dialogflow will bill you for the audio so far.
   • Dialogflow discards all Speech recognition results in favor of the text input.
   • If StreamingAnalyzeContentRequest.config in the first message was set to StreamingAnalyzeContentRequest.text_config, then the second message must contain only input_text. Moreover, you must not send more than two messages. After you sent all input, you must half-close or abort the request stream.

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ participant	string Required. The name of the participant this text comes from. Format: projects/<Project ID>/locations/<Location ID>/conversations/<Conversation ID>/participants/<Participant ID>.
↳ audio_config	InputAudioConfig Instructs the speech recognizer how to process the speech audio.
↳ text_config	InputTextConfig The natural language text to be processed.
↳ reply_audio_config	OutputAudioConfig Speech synthesis configuration. The speech synthesis settings for a virtual agent that may be configured for the associated conversation profile are not used when calling StreamingAnalyzeContent. If this configuration is not supplied, speech synthesis is disabled.
↳ input_audio	string The input audio content to be recognized. Must be sent if audio_config is set in the first message. The complete audio over all streaming messages must not exceed 1 minute.
↳ input_text	string The UTF-8 encoded natural language text to be processed. Must be sent if text_config is set in the first message. Text length must not exceed 256 bytes for virtual agent interactions. The input_text field can be only sent once, and would cancel the speech recognition if any ongoing.
↳ input_dtmf	TelephonyDtmfEvents The DTMF digits used to invoke intent and fill in parameter value. This input is ignored if the previous response indicated that DTMF input is not accepted.
↳ query_params	QueryParameters Parameters for a Dialogflow virtual-agent query.
↳ assist_query_params	AssistQueryParameters Parameters for a human assist query.
↳ cx_parameters	Google\Protobuf\Struct Additional parameters to be put into Dialogflow CX session parameters. To remove a parameter from the session, clients should explicitly set the parameter value to null. Note: this field should only be used if you are connecting to a Dialogflow CX agent.
↳ enable_extended_streaming	bool Optional. Enable full bidirectional streaming. You can keep streaming the audio until timeout, and there's no need to half close the stream to get the response. Restrictions: - Timeout: 3 mins. - Audio Encoding: only supports AudioEncoding.AUDIO_ENCODING_LINEAR_16 and AudioEncoding.AUDIO_ENCODING_MULAW - Lifecycle: conversation should be in Assist Stage, go to Conversation.CreateConversation for more information. InvalidArgument Error will be returned if the one of restriction checks failed. You can find more details in https://cloud.google.com/agent-assist/docs/extended-streaming
↳ enable_partial_automated_agent_reply	bool Enable partial virtual agent responses. If this flag is not enabled, response stream still contains only one final response even if some Fulfillments in Dialogflow virtual agent have been configured to return partial responses.
↳ enable_debugging_info	bool If true, StreamingAnalyzeContentResponse.debugging_info will get populated.
