The problem has never been lack of desire to improve 0 A.D. unit voices, the topic has been raised many times :-) The problem is finding someone to take charge of that project, and with regards to making the recordings, most people don't have experience or access to quality equipment for that. There may be ancient Greek scholars, native Greeks, and voice actors perusing this forum, but I don't know if anyone meets all 3 roles, maybe that is why there's no progress made. Obviously, if the phrases are wrong, we should fix those before even thinking about how they sound, much less recording them.
