Topic-143: Secondary Articulatory Gestures (SAG) While discussing vowels, we need to highlight some of the secondary articulation related to vowels. Remember that secondary articulation is an articulatory gesture with a lesser degree of closure occurring at approximately the same time as another (primary) gesture. It is different than co-articulation which is at the same time and of the same value (taking place as an equal level gesture. Thus it is appropriate to consider four types of secondary articulations in conjunction with vowels because they can usually be described as added vowel-like articulations including palatalization (adding a high front tongue gesture as in sound i, velarization (raising of the back of the tongue, pharyngealization (it is the superimposition of the narrowing of the larynx) and labialization (the addition of lip-rounding).
