Hi, I see you also reposted to here, High latency (5-8 seconds) with Google Gemini Realtime plugin over SIP - #2 by LiveKit-Community. Whilst that ticket is tagged for self-hosting LiveKit (and I see you are using LiveKit cloud), the advice there (to compare your performance with an alternative realtime model) still holds. At the very least, it would help you isolate the root cause of the latency.
Interested in others’ thoughts - there are folks in this community with a lot more experience with Gemini Realtime than me!
