Sounds like your turn detection or endpointing is firing too early, or the STT partials are triggering responses before the user is done — that’s usually why you get cut-offs or lag. I’ve tuned VAPI setups to hit sub-2s latency without interrupting speakers by balancing silence thresholds, barge-in, and the right STT/LLM/TTS combo.
Happy to help dial this in properly.
What STT and LLM are you currently using?
