depressor anguli oris
lifts corner of mouth or compresses lips
levator anguli oris
helps pucker and round lips

how do oro-facial muscles effect speech sounds?
shape of the mouth- closed, opened, rounded lips, spread lips
spread lip sounds [i]
buccanator resoris
rounded lips sounds [u], [w]
obiqularis oris
how do pharyngeal muscles effect speech sounds?
