so i downloaded teto's english CVVC voicebank, and ive had this issue for a while, in which some sounds work fine, but others seem to be missing. ive tested this while making my own USTs, and on a UST of a cover of ECHO by ashita-tsukiloid on soundcloud. for example, the [@t] sound which would be used for the word "what" is gone, but the [-w@] sound for the same word plays normally. ive looked into the folder of this english voicebank and some files really do seem to be missing, like the aforementioned [@t]. ive tried reinstalling the voicebank from kasaneteto.jp/en-voicebank.html but that didnt seem to help. does anyone have any idea what the problem might be and how to fix it? specifically, has anyone downloaded teto's english voicebank recently and can say whether they're experiencing the same thing? any help is appreciated, thank you for listening.
here is the beginning of my voicebank's files folder, if anyone wants to take a look:
