Vowel sounds are made with an open mouth and are characterized by their length, the position of the open mouth from beginning to end and whether airflow is also occurring through the nose during pronunciation.

In human languages, vowels typically occur in the middle of syllables, with a consonant before or after. Consonants occur on the margins of syllables, often indicating breaks from one syllable to the next. Some English words consist of a single syllable made up of a vowel that is not followed by a consonant, such as "a" or "I," but this is rare.
