Classification of English phonemesvowels and consonantsThe distinction between vowels and consonants lies in the

2、obstruction of airstream.In the pronunciation of a vowel, the air stream from the lungs meets no obstruction of any kind in the throat, the nose, or the mouth, while in the pronunciation of a consonant, the air stream from the lungs is obstructed in one way or another. Vowels: more sonorantConsonant

3、s: less sonorantVowels: can stand alone; be a word by themselvesConsonants: must combine with vowels to form wordsVowels: can be sungConsonants: cannot be sungVowels: voiced soundConsonants: noisy soundDescription of vowelsThis is a projection of the vowel space in the vocal tract between the hard p

6、art):Lip posture (IPA) The lips can be spread as for i, rounded as for u, or neutral as for .Rounded vowels are produced with the corner of the lips brought forward, while unrounded vowels are produced with the corners pulled back. In English, all the front vowels and the central vowels are unrounde

10、ophthongs vowels with a stable tongue position and vowel quality over timeDiphthongs vowels produced with the tongue moving from one part of the vowel space to another during which the quality changes. The diphthongs in English include /e/ /a/ / /a/ / / /e/ /. 3.1 Classification of diphthongs Closin

11、g diphthongsClassification of diphthongs Centering diphthongsEnglish Consonants1. Classification of English consonantsThere are 24 consonants in English. These consonants may be classified according to the following: 1) place of articulation, 2) manner of articulation, and 3) voicing, i.e. voiced or

12、 voiceless. Manner of articulation means how obstruction is created (发音时气流受阻的方式)For example:According to the manner of articulation we can distinguish: 1) stops (or plosives 爆破音、塞音) 2) fricatives 擦音 3) affricates 塞擦音 4) nasals鼻音 5) lateral(s)流音 6) semi-vowels 半元音Place of articulation refers to the p

13、lace where obstruction is created (气流在何部位受阻)bilabial (双唇音) labiodental (唇齿音) dental (齿间音) alveolar (齿龈音) postalveolar (后齿龈音) retroflex (卷舌音) palatal (腭音) velar (软腭音) uvular (小舌音) pharyngeal (喉壁音) glottal (声门音)According to the place of articulation we may distinguish the following types of consonants

14、: 1) bilabial (two lips 双唇音) 2) labio-dental (top teeth/bottom lip 唇齿音) 3) dental (tongue tip/top teeth 齿音) 4) alveolar (tongue tip/tooth ridge齿龈音) 5) post-alveolar (tongue tip/hard palate 后齿龈音) 6) palate-alveolar (tongue mid/hard palate腭龈音) 7) palatal (tongue mid/hard palate 腭音) 8) velar (tongue ba

If two phonemes ca

17、n occur in the same environment and distinguish meaning, they are in phonemic contrast. EX./p/ and /b/ pin and bin (in initial position)rope and robe (in final position)On the other hand，t and th never contrast each other. They are two allophones of the same phoneme /p/. (它们是同一音位 /t/ 的音位变体) They occ

18、ur in different environments (只出现在不同的语音环境中): EX. t in stop and th in top l in leaf and in feelTwo allophones of the same phoneme are said to be in complementary distribution. (同一个音位的两个音位变体之间的关系是互补分布。)When two different forms are identical in every way except for one sound segment which occurs in the

19、 same place in the strings, the two words are said to form a minimal pair(在两个单词中，同一位置的一个语音，切分成分不同外，其余的都相同，这两个单词就形成了一个最小对立对。) EX. pill bill pill tilltill killkill dilldill gillAccordingly, we can conclude that /p/ /b/ /t/ /d/ /k/ /g/ are phonemes in English. Then all these sound combinations together

20、 constitute a minimal set; they are identical in form except for the initial consonant.Also, beat, bit，bat，boot，but，bait，bite，boat are a minimal set; they are identical in form except for the vowel /i:/ /i/ /e/ / /u:/ / /ei/ /ai/ / /.Some of the minimal pairs for English phonemes: vowels/i:/ / beat

Function words, such as articles, pronouns, conjunctions, prepositions, auxiliaries, possessives and so on. Therefore, these words have both s

44、trong forms and weak forms.The importance of learning unstressed forms Most native speakers of English find an “all-strong form” pronunciation very unpleasant. Learners who are not familiar with the use of weak forms are likely to have difficulty understanding native speakers of English.A weak form

45、of a word differs from a strong one in the following points: 1. By shortening the length of a vowel, e.g. the /i:/ becomes /i/ in be, been, she, me, and the /u:/ becomes /u/ in to, who, you, etc. 2. By reducing some other vowel sounds to the obscure /: all the different vowel sounds in the words suc

46、h as them, at, an, and, are, of, for, etc. become / 3. By omitting a vowel sound as in the words: am, is, have, had, has, will, etc. 4. By dropping a consonant sound as in the words: and, have, has, had, must, will, would, etc.Are there any weakened words in Chinese?豆腐 f 意思 s怎么m了 ArticlesStrong form
