Function

It is movable, consisting of muscle fibers sheathed in mucous membrane, and is responsible for closing off the nasal passages during the act of swallowing.

The soft palate's motion during breathing is responsible for the sound of snoring. Touching the soft palate evokes a strong gag reflex in most people.

The soft palate should have holes forming that function during speech to separate the oral cavity (mouth) from the nose, in order to produce the oral speech sounds. If this separation is incomplete, air escapes through the nose during speech and the speech is perceived as hypernasal.
