■Supported Environments
OS: Windows 11 (it may also work on earlier versions of the OS)
UTAU: Version 0.4 and later (It is unclear whether it is compatible with OpenUTAU)
*Requires .NET 8 Desktop Runtime

​

■Overview
Converts ust according to the conversion rules listed in the dictionary file (txt file).
It ignores anything not listed in the conversion rules. It’s basically brute force. Power!!!

​

■Installation
Please place the entire folder inside the “plugins” folder in your UTAU installation directory.
If there are any nested folders, the plugin will likely not load.

​

■Uninstallation
Please delete the entire folder.

​

■How to Use
① Prepare a .ust file containing a single sound.(You need to remove the suffix.)
② Select the section you want to convert, launch this plugin, and press the “ぱわー” button.
  At this point, you can also select the consonant length. (The default is set to the recommended value of 60.)
③ The conversion will be applied.
　*If a consonant is listed multiple times in the dictionary, the output will be split according to the selected length.
　　For example, when converting 「むぁ=m,u,a」 with a consonant length of 60, the length of “m” will be 30 and the length of “u” will be 30.
　　If you are only performing the conversion without splitting the consonants and vowels, the consonant length will be ignored.
*Since you cannot undo this, we recommend copying the UST file before performing the conversion.
Also, since you cannot use pitch when splitting by consonants and vowels, it's a good idea to remove the pitch beforehand.

■About Dictionary Files
If the conversion target is comma-separated, the plugin will split it into that many phonemes. Even if there are multiple commas,

it will split accordingly.
If the conversion target consists of only one phoneme, it will be converted as-is without being split.
　Example) 「あ=a」 is converted to 「a」
　　　　　 「た=t.a」 is converted to 「t」 and 「a」
　　　　　 「むぁ=m,u,a」 is converted to 「m」「u」 and 「a」
　　　　　 「あ= か」 is converted to 「か」
In other words, this supports not only the separation of consonants and vowels but also constructed languages.
Duplicate entries will be converted or split based on the one listed last.
It works even if there are blank lines in the dictionary file.
It works with both SJIS and UTF-8, but SJIS is recommended.

template.txt is set not to be loaded, so please copy it and customize it as you like.
All entries listed in the OREMO monophonic list are included here.
