Im wondering if any of you guys worked on a "multilingual" agent, basically if the customer speaks in english, it answers in english if the customer speaks in german, it answers in german any way of doing this ?

Yes, you can build a multilingual agent in Vapi! Set your assistant's transcriber to a provider like Google or Deepgram that supports multilingual transcription. Vapi will detect the spoken language and, if you use the

contents

property for messages, will automatically translate responses to match the user's language. Example configuration for a multilingual transcriber:

json
"transcriber": {
  "provider": "google",
  "model": "default",
  "language": "multilingual"
}

See the [multilingual support docs](https://docs.vapi.ai/customization/multilingual) for more details.

By detecting the user’s language, dynamically adjusting prompts, and using multilingual transcription and voice synthesis services, you can build a Vapi assistant that responds in the user’s language.

Absolutely, you can build a multilingual agent in Vapi! By configuring your assistant to use a transcriber provider like Google or Deepgram that supports multilingual transcription, Vapi can detect the language your customer is speaking. If you use the

property for messages, the assistant will automatically translate its responses to match the user's language. This means your agent can seamlessly switch between languages like English and German during a conversation, responding in whichever language the customer uses.

@Kings_big💫 uhm can you elaborate please?

I meant you can make a multilingual Vapi assistant by enabling auto language detection in the transcriber, dynamically adjusting prompts based on the detected language, and selecting matching voice synthesis for natural responses. https://docs.vapi.ai/customization/multilingual

i see that link updates stuff before startging the call { "voice": { "provider": "azure", "voiceId": "es-ES-ElviraNeural" } } my idea is to switch the language once the call has already started, sorry for the insitence but i do not yet understand how to do so ! thank you so much for your time and help

Use these settings for multilingual assistant:

Model: Any
Transcriber: Deepgram - Multi
Voice: 11labs - eleven_turbo_v2_5

thank. you kyle !

yes only the workflow use of google is not posible because it is done for the last 6 days...
