I have an English knowledge base in Trieve which I connected it to Vapi knowledge base. Now I want if user select Spanish, the Vapi gives answers in Spanish. Is there any solution?

Set the assistant’s voice and transcriber to Spanish, then either translate responses on the fly using a service like Azure Translator

@Behzad You should be fine feeding english results to a model expecting to recieve and speak spanish - not need to translate the information for the model to interpret
