Hello. I am building a bot to answer calls in Great Britain. So, I desperately need it to be done in Realtime API with British English accent. The system instruction “Use only British English accent” doesnt help. So is there any reliable way to do that, or there is no such feature?
Have you tried using the new “Ballad” voice?
