Use OpenAI GPT 4o-mini cluster or Groq llama3.1-8b-instant as the LLM and Azure for the voice. There is a workaround for the azure issue currently and I can guide you through it. By using the API tool in the documentation, you will be able to update your assistant to the azure voice of your choice. What you will need:
- Your VAPI API Key (Bearer token)
- The assistant ID you want to update
Once you gather that information, head to this page and enter those into the fields -->
Use the drop-downs to select Voice > AzureVoice > then select String for voiceId
Below is the string value for Isabella
it-IT-IsabellaNeural
After that, hit send request and the response should show your new assistant config
