"startSpeakingPlan": { "waitSeconds": 0, "transcriptionEndpointingPlan": { "onNoPunctuationSeconds": 0.2 }, I would like to change the 0.2 value but can't seem to find it in the UI config. Is there a way to change this?

To change the

onNoPunctuationSeconds

value in Vapi, update your configuration (either via API or code) as shown below:

json
"startSpeakingPlan": {
  "waitSeconds": 0.4,
  "transcriptionEndpointingPlan": {
    "onPunctuationSeconds": 0.1,
    "onNoPunctuationSeconds": 1.5, // Change this value as needed
    "onNumberSeconds": 0.5
  }
}

You may need to update this in your assistant or call config JSON and redeploy or save the changes. If the UI does not expose this field, use the API or code config as shown above. See the [Vapi API documentation](https://docs.vapi.ai/api-reference/calls/create-phone-call) for more details.

Hi andre_serra, If you have questions about integrating a custom transcription service with Vapi, you might find our [Custom Transcriber guide](https://docs.vapi.ai/customization/custom-transcriber) helpful. It provides detailed steps on setting up and implementing a custom transcriber using services like Deepgram, including handling audio streaming and returning transcripts to Vapi. If you need more customization around speech processing or transcription, the recent enhancements with Deepgram and Gladia offer advanced control settings, such as end-of-turn detection thresholds and multi-region support for compliance, as detailed in our [latest changelog](https://docs.vapi.ai/changelog/2025/9/8). Feel free to let me know if you have specific needs or further questions.

I built a direct API endpoint for this to bypass the logic app layer. It handles the signature handshake in real-time so you don't have to poll for status.
