# 2.2.5 f/v
与 k/g 不一样，f/v 的发声重点是可以看到的：下嘴唇略微收回，上牙贴在下嘴唇上，而后开始发音。
Unlike k/g, the articulation of f/v is actually visible: the *lower lip* retracts slightly, and the *upper teeth* rest on the lower lip before beginning to sound.
韩语中没有这两个音，所以，他们会不由自主地用 p 替代 f，用 b 替代 v；所以，我们经常会听到韩国人把 *photo* 说成 ˈpoʊˌtoʊ，把 *video* 说成 ˈbɪdioʊ……
The Korean language lacks these two sounds, so Koreans will instinctively replace f with p and v with b. As a result, you often hear Koreans pronouncing *video* as ˈpoʊˌtoʊ and *video* as ˈbɪdioʊ...
中国南方有些方言里也没有 f，所以，他们可能会用 hw 替代 f，比如，把 *fight* 读成 hwaɪt；中文的普通话里没有 v，所以，中国人经常把用 w 替换 v，比如，把 *very* 读成 ˈwɛri……
Some dialects in southern China also lack the f sound, so speakers might substitute f with hw. For instance, they might pronounce fight as hwaɪt. Mandarin Chinese doesn't have a v sound, so Chinese speakers often replace v with w, like pronouncing very as ˈwɛri...
另外需要注意的是，与 p/b、t/d、k/g 不一样，f/v 在发声的时候**不带**任何轻微的元音音色。
Another thing to note is that, unlike p/b, t/d, and k/g, f/v are pronounced *without* any slight vowel qualities.
