So, I'm using Ruko's male whisper vcv voicebank and the program doesn't seem to be able to read all the syllables properly. For example, when I try to play -owo or -ino syllables, no sound comes out. This seems to affect only syllables constructed around the kana from the o collumn (e.g wo, no, to) so I thought there might be something wrong with the voicebank or how the original zip file was extracted. I heard that when voicebanks with zip format are extracted, they often have some complications. Is this one of those complications? And even if it isn't, what should I do to fix the voicebank?
