美语听力与发音技巧 第20期（清浊辅音的区别）
Welcome to Daily Tips on Learning English. Today’s tip is on the difference between voiced and voiced pairs of consonants 1.
This difference is important, as it is the basis for learning other aspects of spoken English. First, let’s explain this difference. Let’s compare some consonants, for example, t, d, p, b, k, g, s, z. These sounds differ only in that the first is voiceless and the second is voiced. Put your hand in front of your mouth and say” “t”, then say “d”. Try it again with “s”, “z”. Did you notice that “t”, “s” have more breath or air coming out of your mouth than “d”, “z”. Now put your hand around the front of your throat. Try it again. Say “t”, “d”, “s”, “z”. Did you notice that “t”, “s” have no vibration 2, whereas “d”, “z”, there’s a vibration?
The sounds with a lot of breath but no vibration are called voiceless, because the vocal 3 cords are not vibrating. The sounds with little breath but a lot of vibration are called voiced, because the vocal cords are vibrating. Tomorrow we will discuss how vowels 5 followed by voiceless consonants are shorter than vowels followed by voiced consonants.
Let’s just look at one example today. “bet”, “bed”. Did you notice how the vowel 4 sound “e” is shorter before “t” and longer before “d”? Tune 6 in tomorrow for more examples of this feature of English. That has been today’s tip on learning English.
- Consonants are frequently assimilated to neighboring consonants. 辅音往往被其邻近的辅音同化。 来自《简明英汉词典》
- Vowels possess greater sonority than consonants. 元音比辅音响亮。 来自《现代英汉综合大词典》
- There is so much vibration on a ship that one cannot write.船上的震动大得使人无法书写。
- The vibration of the window woke me up.窗子的震动把我惊醒了。
- The tongue is a vocal organ.舌头是一个发音器官。
- Public opinion at last became vocal.终于舆论哗然。
- A long vowel is a long sound as in the word"shoe ".长元音即如“shoe” 一词中的长音。
- The vowel in words like 'my' and 'thigh' is not very difficult.单词my和thigh中的元音并不难发。
