Well, well. UNL is (Eastern) Unthinkable Natural Law (TH12.3)
As it is updated to version 1.10 there was still no English patches. But this problem didn't last long. I forgot where I found it. But there is an introduction about it.
http://www.touhouwiki.net/wiki/Touhou_HisoutensokuAfter that, there is a voice patch which can be used on SWR and UNL. But at that time, there were some characters missed, Suika, Suwako, Youmu and Remilia. The first release time was August, three months later, the missed characters' voice has been released as well. Unfortunately, I didn't collect all the characters' voice at the same time, so even now I have all characters' voice, I can't give you a single link which contain all the characters' voice.
However, no matter English patch or voice patch, these patches are not the official ones, the players made it by themselves.
