Yea sure, I had few projects where clients demanded from me that the voice agent speaks only their native language (usually it was either <5m worldwide speakers) and to match their accent. At first I thought it was almost impossible to do such task but soon I realised that is very simple. First of all you should seek and find what language you want your voice agent to speak. After you have that sorted out and have specific language, go onto the either 11labs or Microsoft Azure platofrms and search for the that particular language and find the ideal voice. When you find the perfect voice that you are happy with, head back to the VAPI and change the setting and add API key from the platform your voice is and connect it (If you have trouble with that, please feel free to DM me any time I'll help you). -- NOTE: If you experience any trouble with the accent and the speaking erros you need to either strictly put inside of your system prompt clear instruction about speaking and accent. If you still have the error DM me
