Inputs: Client Messages

Client Messages are JSON-formatted commands that the client sends to the Deepgram server over the WebSocket connection during a voice agent interaction. These messages allow the client to control various aspects of the conversation, configure the agent, and provide necessary information.

• Settings: Initializes the voice agent, sets up audio transmission formats, and optionally provides conversation history context before any voice data is exchanged.
• Update Listen: Updates the Listen configuration on the fly — adjust EOT thresholds, keyterms, and language hints without restarting the session.
• Update Think: Replaces the entire Think provider configuration, including the model, prompt, endpoint, and functions.
• Update Speak: Enables changing the Speak model during the conversation.
• Inject Agent Message: Triggers an immediate statement from the agent.
• Inject User Message: Sends a text-based message to the agent as if the user had spoken it.
• Update Prompt: Updates the system prompt of the agent during the conversation.
• Force End Turn: Ends the current user turn immediately. Requires a Deepgram V2 (Flux) listen provider.
• Function Call Response: Sends the result of a function call back to the server.
• Agent Keep Alive: Maintains the connection to prevent timeouts.

For more detailed information on the format and usage of each message, refer to the individual documentation pages for each message.
