The answer is unfortunately no. A project always has to have a language selected. Normally you won’t work with the same talent for several languages but even if you are about to work with a multi-lingual talent you will have to create one project per language. Of course, you will be able to record shorter phrases in more than one language in the same project if the main script is in the selected language and the voice talent can do it.
