I'm having quite a few difficulties with the Brazilian Portuguese STT provider. Do you recommend any?

Recommendation: For Brazilian Portuguese, try using Deepgram with the

Nova 2

or

Nova 3

model and the

Multi

language setting, as it is recommended for speed and multilingual accuracy. Here’s a sample configuration:

json
{
  "transcriber": {
    "provider": "deepgram",
    "model": "nova-2",
    "language": "multi"
  }
}

Test with native speakers to validate accuracy and adjust as needed. (According to the documentation I have found, Deepgram is generally recommended for speed and multilingual support.) Sources: - [Multilingual support documentation](https://docs.vapi.ai/customization/multilingual) - [Multilingual agent example](https://docs.vapi.ai/assistants/examples/multilingual-agent)

When using Deepgram Nova 2 Multilanguage, the transcription has been getting confused with Spanish and French, causing the agent's language to switch. Do you recommend any alternatives?

Hey, I’ve seen this issue happen with Deepgram multilingual models when they mix up nearby languages. You can try OpenAI Whisper, Speechmatics, or AssemblyAI , all perform better for Brazilian Portuguese. I can help you test and fine-tune whichever you choose for more consistent results. Do you notice the mix-ups happening more in noisy or quiet environments? @luiz.coelho.sunhub

Hi Luiz Coelho, Here are the recommended providers for multilingual support including Portuguese[1](https://docs.vapi.ai/customization/multilingual): 1. Deepgram (Recommended): - Use Nova 2 or Nova 3 with "Multi" language setting - Supports 100+ languages including Brazilian Portuguese - Offers best balance of speed and accuracy - Full auto-detection capabilities 2. Google STT (Alternative): - Use Latest model with "Multilingual" language setting - Supports 125+ languages including Brazilian Portuguese - May be slower but offers broad language support Configuration example for Deepgram:

{  "transcriber": {    "provider": "deepgram",    "model": "nova-2",  // or "nova-3"    "language": "multi"  }}

Other providers like Assembly AI, Azure STT, Whisper, etc. support Portuguese but don't offer automatic language detection, which may be important for Brazilian Portuguese recognition.
