### Answer Yes, Vapi supports multilingual capabilities, allowing you to set up an agent that can understand and respond in multiple languages. Multilingual support is primarily facilitated through the transcribers and text-to-speech (TTS) providers used in the voice pipeline. Here's how you can set up multilingual support in your assistant: 1. **Transcriber (Speech-to-Text)**: Vapi supports providers like Deepgram and Talkscriber, which offer models for various languages. You can configure different transcribers for different languages as needed [(1)]() . 2. **Voice (Text-to-Speech)**: For TTS, you can choose from providers like PlayHT, 11labs, Azure, and others that support multiple languages. For example, Azure supports approximately 400 prebuilt voices across 140 languages and variants. Here is an example configuration for an assistant that supports both English and Spanish:

json
{
  "voice": {
    "provider": "azure",
    "voiceId": "en-US-JennyNeural"
  },
  "transcriber": {
    "provider": "deepgram",
    "model": "nova-2",
    "language": "en"
  },
  "model": {
    "provider": "openai",
    "model": "gpt-4"
  }
}

{
  "voice": {
    "provider": "azure",
    "voiceId": "es-ES-ElviraNeural"
  },
  "transcriber": {
    "provider": "deepgram",
    "model": "nova-2",
    "language": "es"
  },
  "model": {
    "provider": "openai",
    "model": "gpt-4"
  }
}

For dynamically switching languages based on user input, ensure your application logic can handle checking for the user's language preference and then selecting the appropriate assistant configuration. If you face issues with transcribers reverting to English after publishing, it might be a known issue that has been addressed. Ensure your settings are saved correctly and try refreshing your setup [(2)]() , [(3)]() .
