What is Persian or Farsi diacritization?
Persian diacritization—also called vowelization, vocalization, harakat, tashkeel, or e'rab-gozari—adds missing pronunciation marks to Persian script. Persian normally leaves short vowels such as zabar, zir, and pish and many Ezafe connections unwritten. VowelMarks makes those sounds visible so a word you already understand in speech is easier to recognize on the page.
