I’ve recorded quite a lot of corporate voiceovers for the team at Media-Paten in Germany.
My work has been with their production studio but they also have a recently relaunched data base of voice artists.
It might be a good place to start if you are looking for German voice talent. In fact it might also be a good source of voice artists with Italian, or Norwegian, or Swedish or Russian language skills. They also offer Arabic, Bengali and Turkish. There are many other nationalities represented on their listing too – but rather than take my word for it you can check it out by following the link to the Die Media Paten voiceover website
