Ejective consonants are all obstruents.
Voiced ejectives are thought by many writers to be impossible. Ejectives are symbolised by placing an apostrophe after the symbol for a voiceless consonant symbol. Ejectives are found in contrast to pulmonic egressive sounds in languages of North and Central America, many languages in Africa and in Caucasian languages. Other languages often use ejectives as positional or stylistic variants of pulmonic egressive sounds. In American writings the term ejective is often replaced by the term glottalised.
