The AI I created for handling phone calls is having a very serious issue understanding my responses and replying to them. I don't know if it's because my client wants the process in Brazilian Portuguese or if it's something else. When I make a call, it either doesn't respond to what I said, takes too long to reply, or gives me the wrong answer. What should I do?

To address issues with understanding and response in Brazilian Portuguese, make sure your assistant is configured with both a transcriber and a voice that support Brazilian Portuguese. For example, set the voice like this:

json
"voice": {
  "provider": "azure",
  "voiceId": "pt-BR-FranciscaNeural"
}

Also, select a transcriber model that supports Portuguese in your assistant's settings. This ensures accurate speech recognition and natural responses in your target language. Tip: After updating, test the assistant and adjust speech configuration settings if you still experience delays or misinterpretations. [See multilingual setup details](https://docs.vapi.ai/customization/multilingual) Source: - [Multilingual support documentation](https://docs.vapi.ai/customization/multilingual)

Switch to Brazilian Portuguese ASR and TTS models, reduce response latency by adjusting endpointing and audio settings, enable multiple ASR hypotheses for better speech recognition, test with real PT-BR inputs..

I've already made those changes, so I think what's happening must be normal. Now the only problem I don't understand is why the call gets disconnected out of nowhere. I increased the call timeout to the maximum, but it didn't change — it would hang up right after answering

Send your call id

How do I get this ID?

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

The phone number ID is "821d4c2b-9741-4bc3-b64d-16be56ad9dd0"

Sounds, good. Closing the ticket.
