Initiation: Settingair in motion through the vocal tract
Phonation: The modification of airflow as it passes through the larynx (related to voicing)
Articulation: The shaping of airflow to generate particular sound types (related to manner)
Articulatory phonetics refers to the aspects of phonetics which looks at how the sounds of speech are made with the organs of the vocal tract (Ogden, 2009:173)
Articulatoryphonetics is divided into three areas to describe consonants: voice, place, and manner
Voice, place, and manner combine together in the production of speech
Voiced sounds involve vocal fold vibrations when produced
Examples of voiced sounds in English are /b,d,v,m/
Voiceless sounds are produced with no vocal fold vibration
Examples of voiceless sounds in English are /s,t,p,f/
Active articulator moves towardsanother articulator in the production of a speech sound
Active articulator forms a closure of some type in the vocal tract
Passive articulator remains stationary in the production of a speech sound
Often, the passive articulator is the destination that the active articulator moves towards
Bilabial sounds involve upper and lower lips coming into contact
In English, /p,b,m/ are bilabial sounds
Labiodental sounds involve lower lip and upper teeth coming into contact
Labiodental sounds can be endolabial or exolabial
Examples of labiodental sounds in English are /f,v/
Dental sounds involve the tongue tip making contact with the upper teeth
Examples of Dental sounds in English are / θ, ð/
Alveolar sounds involve the frontportion of the tongue making contact with the alveolar ridge
Examples of alveolarsounds in English are /t,d,n,l,s/
Postalveolar sounds are made a littlefurtherback from the alveolar ridge
Postalveolar sounds are produced when the bladeof the tongue comes into contact with the post-alveolar region of the mouth
Examples of post-alveolar sounds in English are / ʃ, ʒ /
Palatal sounds are made with the tonguebody raising towards the hard-palate
An example of a palatal sound in English is /j/
Velar sounds are made when the backofthetongue raises towards the soft palate
Examples of velar sounds in English are /k,g ŋ /
Stoparticulations involve a complete closure in the vocal tract
Stop articulations can be oral (plosives) or nasal (nasals)
Plosives are sounds made with a complete closure in the oral tract
Velum is raised during a plosive sound to preventair from escaping via the nasal cavity
English plosives are /p,b,t,d,k,g/
Nasals are sounds made with a complete closure in the oral tract
Velum is lowered during nasal sounds to allowairflow to escape through the nasal cavity
Nasal sounds in English are /m,n, ŋ/
Fricative sounds are produced by narrowing the distance between the active and passive articulators
This causes turbulent airflow when passing between the two articulators
English fricatives include sounds like / f,v, θ,ð, s,z, ʃ,ʒ /
Approximant sounds are created by narrowingthedistance between the two articulators
