What is a key characteristic of consonants in speech?

A key characteristic of consonants in speech is that they can only be spoken in staccato bursts. This means that consonant sounds are often produced in a more abrupt and constricted manner compared to vowel sounds, which are typically more open and sustained. Consonants require closure or constriction in the vocal tract, which leads to a shorter duration of sound, making them sound as if they are articulated in bursts.

In contrast, vowels are usually longer-lasting and can be held out more easily. The nature of consonants leads to a distinct rhythm in speech, where they appear as shorter segments compared to the more fluid and elongated qualities of vowel sounds. This staccato characteristic contributes significantly to the clarity and structure of spoken language.
