Google Cloud Dialogflow v2 API - Class StreamingAnalyzeContentRequest (4.19.0) 

public sealed class StreamingAnalyzeContentRequest : IMessage<StreamingAnalyzeContentRequest>, IEquatable<StreamingAnalyzeContentRequest>, IDeepCloneable<StreamingAnalyzeContentRequest>, IBufferMessage, IMessage

Reference documentation and code samples for the Google Cloud Dialogflow v2 API class StreamingAnalyzeContentRequest.

The top-level message sent by the client to the [Participants.StreamingAnalyzeContent][google.cloud.dialogflow.v2.Participants.StreamingAnalyzeContent] method.

Multiple request messages should be sent in order:

  1. The first message must contain [participant][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.participant], [config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.config] and optionally [query_params][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.query_params]. If you want to receive an audio response, it should also contain [reply_audio_config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.reply_audio_config]. The message must not contain [input][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.input].

  2. If [config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.config] in the first message was set to [audio_config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.audio_config], all subsequent messages must contain [input_audio][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.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.
    1. If [StreamingAnalyzeContentRequest.config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.config] in the first message was set to [StreamingAnalyzeContentRequest.text_config][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.text_config], then the second message must contain only [input_text][google.cloud.dialogflow.v2.StreamingAnalyzeContentRequest.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.

  • Audio Encoding: only supports [AudioEncoding.AUDIO_ENCODING_LINEAR_16][google.cloud.dialogflow.v2.AudioEncoding.AUDIO_ENCODING_LINEAR_16] and [AudioEncoding.AUDIO_ENCODING_MULAW][google.cloud.dialogflow.v2.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.
