Conversational AI of Tencent RTC provides rich metric callbacks. The metric callbacks are sent through custom messages of Tencent RTC, allowing you to easily monitor conversation performance in the client. Metrics such as LLM and TTS call duration and performance are pushed to terminals in real time via custom messages of Tencent RTC, enabling monitoring of AI conversation duration and quality.
You can use the Receive Custom Messages feature provided by the RTC Engine SDK to listen to callbacks in the client to receive the AI conversation metric data. The cmdID value is fixed at 1.
