- 1唇音（雙唇音如 p/b/m；唇齒音如 f/v 有時另稱 labiodental）
A labial is a speech sound you make with one or both lips. Say p, b, or m: both lips close — those are the clear classroom examples, often called . Say f or v: the top teeth touch the bottom lip. Those still use a lip, so many teachers still file them under labial; though actually, careful books give them their own name, labiodental, because the teeth are doing half the work. You will meet labial as a noun (“/p/ is a labial”) and as an adjective (“labial ”). In medical talk it can also mean “of the lips” more generally, but the sense you are learning here is the sound. It is a teacher's and linguist's word, not everyday chat. It has nothing to do with a laboratory, even though the first letters look the same.
組成From Medieval Latin labiālis (“of the lips”), from Latin labium (“a lip”) + -ālis (“-al”). By surface analysis, labi(um) + -al.

entertainmentlifestylemusicAn organ pipe having a lip that influences its sound.
- All organ pipes are divided into two general classes, labial and lingual pipes. The main difference between the two classes is the manner by which the vibrations producing the sound are caused. In labial pipes the column of air entering the pipe under pressure is set in vibration by a fixed obstruction at the mount of the pipe. […] [T]he obstruction at the mouth […] causes the column of air to vibrate. In the lingual or reed pipe, the vibrations are caused by the air passing through a metal reed, which causes the tongue of the reed to vibrate, thereby setting up sympathetic vibrations in the column of air in the pipe.
