Pulmonic consonant

Pulmonic consonants are sounds produced with air from the lungs. They are the most common type of consonant in languages. Other kinds use different air pressures, such as ejectives, implosives, and clicks. Ian Maddieson studied 566 languages and found that 152 have one or more non-pulmonic types. That means about 73% of languages have only pulmonic consonants. For more on the non-pulmonic types, see glottalic consonants and click consonants.
