Voice Activity Detection (VAD) decides how long to wait in silence before assuming the person has finished talking. Set it too low, and the agent interrupts mid-sentence the moment someone pauses to think.
Most default VAD timeouts are tuned for fast back-and-forth exchanges, not natural speech with pauses — which is why this shows up constantly in early voice-agent builds and reads as a "broken" integration when it's really just one number.
The fix:
most voice platforms expose this as a configurable silence-timeout setting. 700ms is a reasonable starting point for natural conversation — long enough to allow a normal pause, short enough that the agent doesn't feel sluggish to respond.
