Stress marks for Ukrainian and Belarusian text

They are homographs: the same spelling with different stress and meaning, like Ukrainian за́мок (castle) and замо́к (lock), or Belarusian ра́кі (crayfish) and ракі́ (of the river). The tool picks a reading from the words around it — for example, after a preposition that needs the genitive — and otherwise shows the most frequent one. Click the word to see all readings and choose.

Voices that read a plus before the stressed vowel, such as Silero and Yandex SpeechKit, need «+а». Ukrainian StyleTTS2 voices and several stress datasets write the plus after the vowel. If a voice ignores special characters, try the capital-vowel format. For reading and printing, keep the accent over the vowel.

Type the vowel, then 0301, and press Alt+X — Word turns the code into an accent over the vowel. Or copy the mark with the «Mark ◌́» button and paste it right after the vowel. To mark a whole document at once, open the «Document» tab and drop the .docx file there.

On the public UNLP-2025 Ukrainian stress benchmark (1026 sentences) the tool marks about 88% of words with two or more syllables correctly, and about 75% of homographs. Words the dictionary does not know get a guess from the ending, shown with a dashed underline so you know to check them.

Yes. A Word (.docx) or OpenDocument (.odt) file comes back with the stress marks inside the text, keeping fonts, tables and images; the marks go into the very run that holds each vowel. Subtitle files (.srt, .vtt) and plain text open in the editor, and the download keeps their format.

Ukrainian — from Wiktionary word forms (the English and Russian editions, via kaikki.org); Belarusian — from GrammarDB, the grammar database of bnkorpus, current spelling only. Both are published under CC BY-SA 4.0. Frequency lists only decide which reading of a homograph comes first.
