Method Detail

• visitConversationItemCreate

   abstract T visitConversationItemCreate(ConversationItemCreateEvent conversationItemCreate)

  Add a new Item to the Conversation's context, including messages, function calls, and function call responses. This event can be used both to populate a "history" of the conversation and to add new items mid-stream, but has the current limitation that it cannot populate assistant audio messages.

  If successful, the server will respond with a conversation.item.created event, otherwise an error event will be sent.

• visitConversationItemDelete

   abstract T visitConversationItemDelete(ConversationItemDeleteEvent conversationItemDelete)

  Send this event when you want to remove any item from the conversation history. The server will respond with a conversation.item.deleted event, unless the item does not exist in the conversation history, in which case the server will respond with an error.

• visitConversationItemRetrieve

   abstract T visitConversationItemRetrieve(ConversationItemRetrieveEvent conversationItemRetrieve)

  Send this event when you want to retrieve the server's representation of a specific item in the conversation history. This is useful, for example, to inspect user audio after noise cancellation and VAD. The server will respond with a conversation.item.retrieved event, unless the item does not exist in the conversation history, in which case the server will respond with an error.

• visitConversationItemTruncate

   abstract T visitConversationItemTruncate(ConversationItemTruncateEvent conversationItemTruncate)

  Send this event to truncate a previous assistant message’s audio. The server will produce audio faster than realtime, so this event is useful when the user interrupts to truncate audio that has already been sent to the client but not yet played. This will synchronize the server's understanding of the audio with the client's playback.

  Truncating audio will delete the server-side text transcript to ensure there is not text in the context that hasn't been heard by the user.

  If successful, the server will respond with a conversation.item.truncated event.

• visitInputAudioBufferAppend

   abstract T visitInputAudioBufferAppend(InputAudioBufferAppendEvent inputAudioBufferAppend)

  Send this event to append audio bytes to the input audio buffer. The audio buffer is temporary storage you can write to and later commit. In Server VAD mode, the audio buffer is used to detect speech and the server will decide when to commit. When Server VAD is disabled, you must commit the audio buffer manually.

  The client may choose how much audio to place in each event up to a maximum of 15 MiB, for example streaming smaller chunks from the client may allow the VAD to be more responsive. Unlike made other client events, the server will not send a confirmation response to this event.

• visitInputAudioBufferClear

   abstract T visitInputAudioBufferClear(InputAudioBufferClearEvent inputAudioBufferClear)

  Send this event to clear the audio bytes in the buffer. The server will respond with an input_audio_buffer.cleared event.

• visitOutputAudioBufferClear

   abstract T visitOutputAudioBufferClear(RealtimeClientEvent.OutputAudioBufferClear outputAudioBufferClear)

  WebRTC Only: Emit to cut off the current audio response. This will trigger the server to stop generating audio and emit a output_audio_buffer.cleared event. This event should be preceded by a response.cancel client event to stop the generation of the current response. Learn more.

• visitInputAudioBufferCommit

   abstract T visitInputAudioBufferCommit(InputAudioBufferCommitEvent inputAudioBufferCommit)

  Send this event to commit the user input audio buffer, which will create a new user message item in the conversation. This event will produce an error if the input audio buffer is empty. When in Server VAD mode, the client does not need to send this event, the server will commit the audio buffer automatically.

  Committing the input audio buffer will trigger input audio transcription (if enabled in session configuration), but it will not create a response from the model. The server will respond with an input_audio_buffer.committed event.

• visitResponseCancel

   abstract T visitResponseCancel(ResponseCancelEvent responseCancel)

  Send this event to cancel an in-progress response. The server will respond with a response.done event with a status of response.status=cancelled. If there is no response to cancel, the server will respond with an error.

• visitResponseCreate

   abstract T visitResponseCreate(ResponseCreateEvent responseCreate)

  This event instructs the server to create a Response, which means triggering model inference. When in Server VAD mode, the server will create Responses automatically.

  A Response will include at least one Item, and may have two, in which case the second will be a function call. These Items will be appended to the conversation history.

  The server will respond with a response.created event, events for Items and content created, and finally a response.done event to indicate the Response is complete.

  The response.create event includes inference configuration like instructions, and temperature. These fields will override the Session's configuration for this Response only.

• visitSessionUpdate

   abstract T visitSessionUpdate(SessionUpdateEvent sessionUpdate)

  Send this event to update the session’s default configuration. The client may send this event at any time to update any field, except for voice. However, note that once a session has been initialized with a particular model, it can’t be changed to another model using session.update.

  When the server receives a session.update, it will respond with a session.updated event showing the full, effective configuration. Only the fields that are present are updated. To clear a field like instructions, pass an empty string.

• visitTranscriptionSessionUpdate

   abstract T visitTranscriptionSessionUpdate(TranscriptionSessionUpdate transcriptionSessionUpdate)

  Send this event to update a transcription session.

• unknown

   T unknown(JsonValue json)

  Maps an unknown variant of RealtimeClientEvent to a value of type T.

  An instance of RealtimeClientEvent can contain an unknown variant if it was deserialized from data that doesn't match any known variant. For example, if the SDK is on an older version than the API, then the API may respond with new variants that the SDK is unaware of.
