09/10/2025, 4:55 PMCould you please share a bit more about the usage metrics for your call? For instance, the duration of the call, how many participants were involved, and the specific usage of STT (speech-to-text), LLM (language model), and TTS (text-to-speech) during the session. This information will really help us make sure we calculate the cost accurately for you.

09/10/2025, 4:58 PMAre you currently using any specific LiveKit APIs or metrics to keep track of the usage for STT, LLM, and TTS? Also, do you happen to have the pricing details for these services on hand? Having this information will really help me guide you through the exact code changes you might need.
