Vowels are speech sounds made without any significant constriction or blockage of air flow in the vocal tract, while consonants are made with a noticeable constriction.
Vowels vs. Consonants

Key Differences

Vowels are characterized by the open configuration of the vocal tract, allowing a smooth flow of air. In contrast, consonants involve a degree of closure or narrowing in the vocal tract, impacting the sound's quality.

Vowels form the nucleus of syllables and are essential for their formation; they can stand alone or with consonants. Consonants, however, typically require vowels to form syllables and are rarely found in isolation.

The way vowels are produced involves the shape and position of the tongue and lips, but without significant airflow restriction. Consonants, on the other hand, are produced by obstructing the vocal tract, either partially or completely.
