Ch 4: Vowels Flashcards
The Tongue
The primary articulator in the production of vowels.
Vowel
Phonemes that are produced without any appreciable constriction or blockage of air flow in the vocal tract.
Tongue Height
Refers to how high in the oral cavity the tongue is when producing a particular vowel.
Tongue Advancement
Refers to how far forward (or backward) in the mouth the tongue is when producing a particular vowel.
Vowel Quadrilateral
A two dimensional figure that demonstrates the points of production in the oral cavity of various vowels.
Lip rounding
The lips can be either rounded or unrounded when producing certain vowels.
Tense Vowels
Usually longer in duration and require more muscular effort than lax vowels. Tense vowels are capable of ending stressed open syllables.
Lax Vowels
Require less muscular effort compared to tense vowels. Lax vowels never end an open syllable.
Monophthongs
A vowel that has one primary articulatory position in the vocal tract during production.
Diphthong
A vowel sound that has two distinct articulatory positions in the vocal tract during production.
Onglide
The first element of a diphthong
Offglide
The second element of a diphthong.
Nasalization
When the phonemic environment of a word or sound causes the sound to resonate in the nasal cavity.
Resonance
Deals with the vibratory properties of any vibrating body.
Quality (Timbre)
The perceptual character of a sound based on its acoustic resonance patterns.
