Question: two manners of articulation that do not occur in english

title: Manner of articulation
text: One use of the word semivowel , sometimes called a glide , is a type of approximant , pronounced like a vowel but with the tongue closer to the roof of the mouth , so that there is slight turbulence . In English , / w / is the semivowel equivalent of the vowel / u / , and / j / ( spelled `` y '' ) is the semivowel equivalent of the vowel / i / in this usage . Other descriptions use semivowel for vowel - like sounds that are not syllabic , but do not have the increased stricture of approximants . These are found as elements in diphthongs . The word may also be used to cover both concepts . The term glide is newer than semivowel , being used to indicate an essential quality of sounds such as / w / and / j / , which is the movement ( or glide ) from their initial position ( / u / and / i / , respectively ) to a following vowel .
