 | | The release of the more forward closure produces what in many cases are the loudest consonants in the language, although in some languages such as Hadza, clicks are more subtle and may even be mistaken for ejective stops. |
 | | Clicks occur in all the Khoisan languages of southern Africa and in several neighbouring Bantu languages, such as Nguni (Zulu, Xhosa, Swazi, Phuthi and Ndebele), Sesotho, Yeyi of Botswana, and the Mbukushu, Kwangali, and Gciriku languages of the Caprivi Strip, which borrowed them from Khoisan languages. |
 | | Some Khoisan languages are typologically unusual in allowing mixed voicing in non-click consonant clusters, such as dt͡s’k͡x’, so it's not unexpected that they would allow mixed voicing in clicks as well, and this can be taken as evidence that these clicks are also clusters. |
