I want the default language to be english but if needed to switch to french and Spanish

Set the default language to English with a multilingual transcriber (

language: "multi"

), and dynamically switch the TTS voice to French or Spanish based on detected language, using either multilingual voices or manual switching in your code.. [https://docs.vapi.ai/customization/multilingual](https://docs.vapi.ai/customization/multilingual?utm_source=chatgpt.com)
