Use this endpoint to broadcast a custom message using the TTS module.

During a conversation with a Conversational AI agent, call this endpoint to immediately broadcast a custom message using the TTS module. Upon receiving the request, Conversational AI interrupts the agent’s speech and thought process to deliver the message. This broadcast can be interrupted by human voice.

Note

The speak API is not supported when using mllm configuration.
