Hello i'm trying to manage the server message ''language-change-detected" but is not possible to set it in the dashboard, also, if i trying use a transational agent, i add this server message in the configuration serverMessages: [ "end-of-call-report", "status-update", "hang", "function-call", "phone-call-control", "language-change-detected" ], but i don't get the "language-change-detected" message (yes i get the others)

According to the information I found, there is no

language-change-detected

event triggered in Vapi, which explains why you're not receiving this message even when configured. For language detection, Vapi uses automated language recognition instead. If you need to handle language changes, consider using the

codeSwitchingEnabled

parameter with your transcriber, which allows recognition of language switches within utterances:

json
{
  "transcriber": {
    "provider": "deepgram",
    "codeSwitchingEnabled": true
  }
}

Note that the transcriber model must support code-switching and the specific languages being used.

Hey! To help track down this issue, could you share: - The call ID This would really help us figure out what went wrong!

Hello! The call ID is : 40370a1f-f4f8-4ff6-b79f-43a11c5dc70c All de conversations with the number from +34911 67 77 69 to + 34 711 717 713 have the same trouble. Thanks

"transcriber": {
      "model": "nova-3",
      "language": "multi",
      "provider": "deepgram",
      "codeSwitchingEnabled": true
    }

Apologies for the delayed response, You have to set codeSwitchingEnabled to true, after that you will get this event.

Hi Shubham, Thanks for the help. According to Deepgram’s official docs,

codeSwitchingEnabled

is supported on both

nova-2

and

nova-3

models. However, when I set

codeSwitchingEnabled: true

with

nova-3

, I get this error from Vapi: >

assistant.transcriber.codeSwitchingEnabled must be false. 'codeSwitchingEnabled' requires the model to be one of: nova-2, nova-2-general.

It seems there's a mismatch between Deepgram's capabilities and what Vapi currently allows. Can you confirm if support for

codeSwitchingEnabled

with

nova-3

will be added soon? Thanks!

Hey, let me check with the team on this why code switching enabled is not supported for the Nova 3 yet.

Thanks Shubham, This feature is important for our company.

You can raise an feature request for it over here: https://roadmap.vapi.ai

How long until this feature is supported in Vapi? Thanks
