Introduction Flashcards
Three branches of phonetics
Articulatory
Acoustic
Auditory
Phonetics
Physical and anatomical aspects of speech sounds
Three parts of the vocal tract
Sublaryngeal
Laryngeal
Supralaryngeal
Three functional components of speech
Initiation
Phonation
Articulation
Initiation
Creates an airstream of aerodynamic energy
Phonation
Adds voicing by converting aerodynamic energy into acoustic energy
Articulation
Shapes the acoustic energy to produce speech sounds
Pulmonic airstream
Initiated in lungs
Exhalation normally 60% - up to 86-90% in speech
Either egressive or ingressive
Glottalic airstream
Glottis closed
Movement of larynx altered air pressure
Egressive electives
Ingressive implosives
Velarised airstream
Closure at velum or uvula
Only ingressive
Clicks
Complete closure
Air completely blocked
Plosives and nasals
Momentary or intermittent
Sound created at constriction
Close approximation
Air partially obstructed
Fricatives
Sounds created at constriction
Open approximation
Air modified
Approximants
Changes resonance
Obstruent
Sound made at place of articulation
Survive the airflow through higher vocal tract
Plosives and fricatives
Sonorant
Sounds made by phonation component
Vowels, nasals, approximants
