This is usually a mix of prompt behavior + latency during function calls, not just a single setting. The repetition (“one moment…”) typically comes from the agent trying to fill silence while waiting on a tool response in platforms like Vapi. You’ll want to tighten your prompt so it only says it once and avoids repeating filler phrases. The silence during function calls is a latency issue — either the function response is slow or there’s no interim audio handling. I’ve fixed this by optimizing the function response time and adding a quick placeholder response while the tool runs. If you want, I can review your setup and help you eliminate both the repetition and delay @flowrpot
