PLACE: Bilabial: [p, b, m] both lips Labio-dental: [f, v] lip & teeth Dental: [†, ∂] tongue tip & teeth Alveolar: [t, d, s, z, l, r, n] tongue tip & AR* Palato-alveolar: [ß, Ω, ß, Ω] tongue blade & AR/ hard palate Palatal: [j] tongue (front) & hard palate Velar: [k, g, Ñ] tongue (back) & velum Labio-velar: [w] lips & tongue (back) & velum Glottal: [h, ÷] vocal cords (glottis) * AR = alveolar ridge MANNER: Plosives: [p, b, t, d, k, g, ÷] closure Fricatives: [f, v, †, ∂, s, z, ß, Ω, h] friction Affricates: [ß,Ω] combination Nasals: [m, n, Ñ] nasal cavity Liquid: [l, r] partly blocked Glides: [w, j] vowel-like 1 Manner of articulation is about how the sound is produced. It is divided into two types: obstruents (obstruction the air-stream causing the heightened air- pressure) and sonorants (no increase of the air-pressure). Then, each of them is further divided into as follows: Manners of articulation Obstruents Sonorants Stops Fricatives Affricates Nasals Approximants (closure → release) (friction) (closure → friction) (through nose) (partial block + free air-stream) Liquids Glides Rhotics Laterals (through center (through sides of tongue) of tongue) Figure 1.
