Tencent RTC Conversational AI provides rich metrics callback features. These status callbacks are sent through Tencent RTC's custom messages, allowing easy monitoring of conversation performance on the client side. Metrics such as LLM and TTS call duration and performance data are pushed to the terminal in real-time via Tencent RTC custom messages, enabling monitoring of Conversational AI duration and quality.
Through the Tencent RTC SDK Receive Custom Messages feature, you can listen for callbacks on the client to receive real AI dialogue metrics data. cmdID is fixed at 1.
