Voice ID URL not working

I am trying to create a live avatar using full mode, but when I try to enter the link for the voices and the voice_id, it says that the link is broken. Without adding the correct ID, the application I am developing does not work. Where can I find the voice IDs for avatars that have already been published, such as Santa Claus?
