| For the insertion of glottal stops before certain consonants, see Glottalization below. |
| Glottalization ceases or modifies phonation by compressing the vocal folds. |
| In Danish the tones have been replaced by glottalization in instances in which Norwegian and Swedish have the first type. |
| For example, although Omotic languages have glottalization, as do most Afro-Asiatic languages, they do not have the pharyngeal consonants that are common among the other members of that phylum. |
