Explanation:

An accented syllable is an emphasized syllable, characterized by increased loudness and vowel length, full articulation of the vowel, and changes in pitch. The meaning of words often depends on the accent, as some words can be spelled the same way but mean different things. The accent can express this difference.

There are many kinds of accents. For example, in some languages, accented syllables are stressed, while in other languages a change in pitch may also occur. These languages are called pitch-accent languages. Serbian, Croatian, Turkish, Japanese, Norwegian, and Swedish are just some examples of this type of language.
