LINB09H3 Chapter Notes - Chapter 11: Dental, Alveolar And Postalveolar Trills, Uvular Trill, Vocal Folds
Document Summary
A primary aspect of manner is the degree of stricture; that is, does the air have a free passage through the mouth or is there obstruction. By varying obstruction, we can make different sounds. Nasality is another way of varying sounds, by allowing air to pass out of the nose or not. As well, some sounds are lateral with the air passing out through the sides of the vocal tract, but not through the middle. Now say [llllllllll]; air still passes through but not as freely. If you try to say [fffff] the closure is even tighter, causing a certain amount of frication or friction-like noise. If you try to [ppppp] your cheeks may puff out a bit; but no air escapes as there is a complete closure. Oral stops, fricatives and affricates together form the class of obstruents. Non-obstruent sound are called sonorants, comprising nasals, approximants and vowels; the sonorants consonants are discusses below.
