Some inputs of DiffSinger depend on whether the phones are vowels. However,
G2pDictionary.IsVowel()
returnsfalse
if the phoneme symbol is not found in the dictionary (mostly dsdict.yaml). The rendering continues because the phoneme exists in the phoneme list (mostly phonemes.txt), but produces wrong results because the types of the phonemes are misconfigured. Many people missed some phonemes in their dictionary and had trouble debugging.This PR adds some checks so that all phonemes should be defined in dictionary if the inputs depend on the phoneme types. If not, OpenUTAU shows an explicit error message.
