Hi team, this is a continuous issue on a lot of our calls our Assistant has quite a delay in response. This causes interruptions in flow of conversations with customers where customers are getting frustrated. FYI - this is for a live client, hoping for a quick solution. Call ID: 3a8b631e-56ac-478a-b110-5c68abc6e385 Issue Timestamp: 00:20 - Assistant takes 5 seconds to respond What we expect to happen: Assistant to respond within 3 seconds or less In settings we have wait seconds set to 1.3.

Hey Beck, to make your assistant respond on time, set Deepgram’s endpointing value to 300 and startSpeakingPlan waitSeconds to 0.8 after that, and the assistant will respond in the required time, capturing and detecting the end of the user’s speech. Let me know how it goes.

Thanks @Shubham Bajaj will try this!

Hi @shubman, can i please confirm where exactly we can set Deepgram's endpoint value to 300? We couldnt find this in Vapi settings. Thanks!

curl -X PATCH https://api.vapi.ai/assistant/insert-your-assistant-id-here \
     -H "Authorization: Bearer <token>" \
     -H "Content-Type: application/json" \
     -d '{
  "transcriber": {
    "provider": "deepgram",
    "codeSwitchingEnabled": false,
    "model": "",
    "endpointing": 300
  }
}'

@Beck you need to make an API request to update your assistant transcriber config, here you need to replace token with your private key and assistant-id with the actual assistant ID.

@Shubham Bajaj Can i please confirm if we adjust this setting to LESS LATENCY - will this improve response time? Would this impact anything else? https://cdn.discordapp.com/attachments/1344177033625997322/1349238094943223848/Screenshot_2025-03-12_at_11.16.32_am.png?ex=67d25f65&is=67d10de5&hm=badc6be6f8847c0f87b01b3b2cc5e8992b781e246f9ea062bdfa7117807334c7&

Hello Beck, adjusting that setting will improve latency without drastically affecting anything else.
