10/25/2025, 5:29 PMnumWords parameter in your stopSpeakingPlan so the agent waits for the caller to say 2-3 words before stopping. This helps avoid interruptions after brief acknowledgments. Here’s an example configuration:
json
"stopSpeakingPlan": {
"numWords": 3,
"voiceSeconds": 0.2,
"backoffSeconds": 1
}
Set this via the API, and adjust numWords as needed to best fit your conversation flow.
For more details, see the [Vapi speech configuration documentation](https://docs.vapi.ai/customization/speech-configuration).
