Hello,
Currently, Retell AI’s core infrastructure is US-based, and we do not have dedicated servers in Europe at this time.
That said, you can go to your agent and at the top left, you can see a breakdown of the latency (by hovering over the pie chart icon).
Here are some settings you can modify on your agent:
-
LLM model: eg. switch to GPT 4.1 mini.
-
Denoising: use lighter denoising.
-
Response Eagerness: increase for more responsiveness.
-
Transcription Settings: Refer to the documentation.
Regards,
Retell Support Team
