Hello Vapi Team, I'm using Deepgram Nova 3 pl/Nova 2 pl for my assistant, and I've noticed that it doesn't collect phone number. I've tried with numerals option on and off, and it still doesn't work. I did this with BYOK and without. When I'm switching to any other stt it works perfectly fine, byt the only issue is with Deepgram. Could you please let me know what is the issue? I really care about using deepgram precisely as it has the lowest latency for polish language.

Thank you for the details. To help diagnose the issue with Deepgram Nova 2 pl / Nova 3 pl not collecting phone numbers, could you please confirm if you have tried adding phone number patterns (e.g., as a

keyterm

for Nova-3 or

keywords

for Nova-2) in your transcriber configuration? This can sometimes improve recognition of specific number formats. If possible, please share a sample of your current transcriber configuration (excluding any sensitive information). Sources: - [Deepgram Transcriber Documentation](https://docs.vapi.ai/providers/transcriber/deepgram) - [Deepgram Custom Keywords & Keyterm Prompting](https://docs.vapi.ai/customization/custom-keywords)

Thanks for the suggestion, but adding specific patterns as keywords/keyterms isn't a viable solution here. I'm building a lead-gen bot where users provide their own unique phone numbers, so I can't hardcode them in the configuration. The issue is that Deepgram (Nova 2/3 PL) fails to transcribe random sequences of digits that form a phone number, while other STT providers handle this natively without any extra prompting.

To improve number transcription with Deepgram in Vapi, ensure you have

smartFormat

enabled in your transcriber configuration. Here’s an example:

json
"transcriber": {
  "provider": "deepgram",
  "model": "nova-3",
  "language": "pl",
  "smartFormat": true
}

If the issue persists with

smartFormat

enabled, please let us know so we can escalate this as a potential integration issue. Source: [Deepgram Transcriber Documentation](https://docs.vapi.ai/providers/transcriber/deepgram)

how can I enable smartformat through dashboard?

To enable

smartFormat

for Deepgram in the Vapi dashboard, look for your assistant's configuration section—typically under "Transcriber" or "Advanced Settings." If available, set the

smartFormat

option to

true

. If you don't see this toggle in the dashboard UI, you may need to switch to the JSON or "Raw Config" editor and add:

json
"smartFormat": true

If the option is not visible, please contact Vapi support for dashboard-specific guidance. Source: [Deepgram Transcriber Documentation](https://docs.vapi.ai/providers/transcriber/deepgram)

It still does not work. Why it happens only on your platform and on every other platform Deepgram Nova 3 works perfectly fine. This is the set up that I have: "transcriber": { "model": "nova-3", "language": "pl", "numerals": true, "provider": "deepgram", "smartFormat": true }, and still it does not catch ANY numbers, as if they have not been spoken. Why is that?
