Labialized sounds involve the lips while the remainder of the [[mouth\|oral cavity]] produces another sound. The term is normally used to refer to [[consonant]]s. When vowels involve the lips, they are usually called [[rounded vowel\|rounded]]. : Peurront: /w, ɹ/ ~~Labialisation may also refer to a type of [[Assimilation (linguistics)\|assimilation]] process.~~ : Damront (pe digor-ont): /ʃ, ʒ, ʧ, ʤ/ : Nann-ront (pe "plaen") ==~~Where~~Doareoù ~~found~~gweuzadur== Labialisation is the most widespread secondary articulation in the world's languages. It is phonemically contrastive in the [[Northwest Caucasian languages\|Northwest Caucasian]], [[Athabaskan languages\|Athabaskan]], [[Salishan languages\|Salishan]], and [[Indo-European languages\|Indo-European]] [[language family\|language families]], among others. [[American English]] has three degrees of (phonetic) labialization: Fully rounded {{IPA\|/w/}} and initial {{IPA\|/ɹ/}}, open-rounded {{IPA\|/ʃ/, /ʒ/, /ʧ/, /ʤ/}}, and unrounded, which in vowels is sometimes called spread. These secondary articulations are not universal. For example, while French shares the English open-rounding of {{IPA\|/ʃ/, /ʒ/}}, Russian does not. Such distinctions are helpful for non-native English speakers whose native languages use different articulations for sounds such as "r" and "l". ~~==Types of labialisation==~~ The most common form of labialisation is rounding of [[dorsal consonant]]s such as k, g, and q. With non-dorsal consonants, labialisation prototypically involves [[velarization]] as well, so it might more accurately be called ''labiovelarisation.'' However, this is not always the case, and labialisation is not restricted to lip-rounding. The following articulations have either been described as labialisation, or been found as [[allophone\|allophonic]] realisations of prototypical labialisation: Linenn 35 ⟶ 31: For simple labialization, Ladefoged and Maddieson resurrected an old IPA symbol, {{IPA\|[ ̫]}}. In Shona, {{IPA\|/s̫/}} and {{IPA\|/z̫/}} contrast with {{IPA\|/s/}} and {{IPA\|/z/}}, and in some dialects with {{IPA\|/sw/, /zw/, /s̫w/, /z̫w/]}} as well. The open rounding of English {{IPA\|/ʒ<sup>œ</sup>/}} is also simple (unvelarized). ==Heñveladur== ~~==Labial assimilation==~~ Alies e vez produet evel disoc'h an [[Heñveladur (yezhoniezh)\|heñveladur]], da lâret eo e vez gweuzet ur gensonenn dindan levezon sonennoù gweuz tro-dro pe tost outi, da skouer: Labialisation also refers to a specific type of assimilatory process where a given sound become labialised due to the influence of neighboring labial sounds. For example, {{IPA\|/k/}} may become {{IPA\|/kʷ/}} in the environment of {{IPA\|/o/}}, or {{IPA\|/a/}} may become {{IPA\|/o/}} in the environment of {{IPA\|/p/}} or {{IPA\|/kʷ/}}. ▼ ▲~~Labialisation also refers to a specific type of assimilatory process where a given sound become labialised due to the influence of neighboring labial sounds.

In the [[Northwest Caucasian languages]] as well as some [[Australian languages]] rounding has shifted from the vowels to the consonants, producing a wide range of labialized consonants and leaving in some cases only two phonemic vowels. This appears to have been the case in Ubykh and [[Eastern Arrernte]], for example. The labial vowel sounds usually still remain, but only as allophones next to the now-labial consonant sounds. ==Gwelit ivez:== * [[Rontder (yezhoniezh)\|Rontder]]▼ * [[Vogalenn]] * [[Kensonenn]] * [[Doare distagañ]] ▲* [[Rontder (yezhoniezh)\|Rontder]] [[Rummad:Fonetik ha fonologiezh]]
