To add a dictionary for your language, you need to create a translation file. For example, UI_EN.

You need these fields:

UI_DrunkSpeech_Dictionary_Filter
UI_DrunkSpeech_Dictionary_Case_Filter

UI_DrunkSpeech_Dictionary_Filter

Example: src/iDrunk/Contents/mods/iDrunk/media/lua/shared/Translate/EN/UI_EN.txt

[
  {
    "needle": [],
    "add": {
      "before": []
    }
  },
  {
    "needle": [],
    "replace": {
      "full": []
    }
  },
  {
    "needle": [],
    "add": {
      "after": []
    }
  }
]

UI_DrunkSpeech_Dictionary_Case_Filter

Here you just need to specify the chars case. You can specify an empty json if you use hieroglyphs, etc.
