The accent in Slovak is always on the first syllable.
NOTE: The acute accent (diacritical mark in letters á, é, í, ó, ú, ý, ĺ and ŕ) does not indicate a stressed syllable! The acute accent indicates that the syllable should be pronounced twice as long as a short syllable. Example:
|ja mám||/ja ma:m/|
Stressed syllables are not marked in Slovak words.
