Unit Three The English Vowels

By 王雪纯 老师 2023-05-13 1536次浏览
  1. Why do we call the English vowels front or central or back vowels?
  2. Why is the vowel /ɪ/ sometimes replaced by the "non-phonemic symbol [i]"?
  3. What are the features of closing diphthongs?

    1. English vowels are called front, central, or back based on the position of the tongue in the horizontal plane when producing the vowel sound.
    • Front vowels: These vowels are produced with the front of the tongue raised toward the front of the mouth. Examples of front vowels in English include /i/ as in "see" and /e/ as in "bed."

    • Central vowels: These vowels are produced with the tongue in a more neutral or central position in the mouth. Examples of central vowels in English include /ə/ as in "about" and /ʌ/ as in "but."

    • Back vowels: These vowels are produced with the back of the tongue raised toward the back of the mouth. Examples of back vowels in English include /u/ as in "too" and /ɔ/ as in "thought."

    These terms describe the general position of the tongue in relation to the mouth during the production of these vowel sounds.

    1. The vowel /ɪ/ in English, as in words like "sit," can vary in its realization depending on the speaker and the phonetic context. In some cases, it may be pronounced with a slightly higher and more close position of the tongue, approaching the sound [i], which is the phonetic symbol for the vowel in words like "see." This variation is called allophony, where different phonetic realizations of a phoneme occur in different contexts. Although [i] is not considered a separate phoneme in English, it can be used as a non-phonemic symbol to represent the allophonic variation of /ɪ/ in certain contexts.
    2. Closing diphthongs, also known as falling diphthongs, are a type of diphthong where the vowel sound glides from a more open position to a closer or more closed position within a single syllable. The features of closing diphthongs include:
    • Glide: Closing diphthongs involve a smooth glide or transition from one vowel quality to another within the same syllable. The starting point is typically a more open vowel sound, while the ending point is a closer or more closed vowel sound.

    • Duration: Closing diphthongs are relatively longer in duration compared to pure vowel sounds. The transition from the starting to the ending vowel creates a longer overall duration.

    • Articulation: Closing diphthongs involve a change in the articulatory position of the vocal tract. For example, in the English closing diphthong /aɪ/ as in "ride," the sound starts with an open vowel /a/ and glides to a closer vowel /ɪ/ within the same syllable.

    Other examples of closing diphthongs in English include /ɔɪ/ as in "boy" and /eɪ/ as in "say."

    Because we particulate different vowels in different ways. 

    • Front vowels are produced with the front of the tongue raised toward the front of the mouth. Examples of front vowels in English include /i/ as in "see" and /e/ as in "bed."

    • Central  vowels are produced with the tongue in a more neutral or central position in the mouth. Examples of central vowels in English include /ə/ as in "about" and /ʌ/ as in "but."

    • Back  vowels are produced with the back of the tongue raised toward the back of the mouth. Examples of back vowels in English include /u/ as in "too" and /ɔ/ as in "thought."

    2.English has a phonetic rule in which vowels are reduced to a/wa/on unaccented syllables. For a morpheme at the bottom of phonological processing, all its vowels actually appear in their original tone. For the morpheme atom, for example, its bottom phonological expression instead would be æt - comparable. In phonological processing, if a syllable is unstressed, its vowel is reduced to a vowel of / /. So, for atom, the sound change instead is actually æt - comparable m→'æt - comparable m, so that to learners of a foreign language, it feels as if the vowels of accented English syllables retain their original tone. In fact, the intonation fluctuation caused by stress in English is very obvious, sometimes even more pronounced than the tonal perception in Chinese. Stress in English is part of the pronunciation of a word and needs to be memorized together. Stress in English is generally reflected by pitch, loudness, syllable length, and pronunciation.

    3.High pitch when pronounced heavy syllables; The pitch is lower when unstressed syllables are pronounced. When stressed syllables are read, the air flow is high; Low air flow when reading unstressed syllables. Stressed syllables sound longer, higher in pitch, and heavier in breath, while unstressed syllables sound shorter, lower in pitch, and weaker in breath. Some words have a primary stress as well as a secondary stress, which means that the syllable is pronounced weaker than the major and stronger than the other syllables.

    For Chinese syllable and can not constitute a separate pronunciation, because Chinese is a tone language, if the syllable does not tone words can not judge its meaning, so to form a complete Chinese pronunciation, tone and syllable is indispensable. So Chinese is one syllable per word, and each word has a tone.
    The length of each rhythm group in English speech is roughly equal, meaning that no matter how many weak syllables there are in the two stressed syllables, they should be read between the two beats.
    Native English speakers also choose to speed up or slow down depending on the number of schwa syllables. The flow of English sounds very smooth, and its pattern of advance is wavy, so English is also known as the accent timing language, with only stressed syllables counted as beats.
    In Chinese, each syllable can be counted as one beat. Although there are stressed beats and weak beats in Chinese, they occupy the same length of time, which is why there are few linking and weak pronunciation in Chinese. Every word was pronounced clearly.
    When we read English, we habitually pronounce each syllable as stressed syllable, which also goes against the pronunciation rules of English vowels and consonants, thus with obvious Chinese pronunciation characteristics.
    Therefore, the rhythm rules of English and Chinese syllables cannot be ignored. We need to understand the differences between the rhythm of English and Chinese syllables, and carry out a lot of perception and recognition training. This can effectively improve our listening level, and let their oral pronunciation more authentic.

    1. Consonant clusters are sequences of two or more consonant sounds that occur together in a word. Some consonant clusters in English deserve special attention due to their complexity or potential challenges in pronunciation. Here are a few examples:
    • Clusters with "s" and "l" sounds: Examples include "sled," "slope," and "slip." These clusters require coordination between the "s" and "l" sounds, which can be challenging for some learners.

    • Clusters with "r" and other consonants: Examples include "prince," "truck," and "spray." The "r" sound in these clusters can be difficult to pronounce, particularly for non-native English speakers.

    • Clusters with "th" and other consonants: Examples include "thumb," "strength," and "cloth." The combination of "th" with other consonants can pose challenges due to the unique nature of the "th" sound.

    • Clusters with nasal consonants: Examples include "strong," "twelve," and "plump." These clusters involve combinations of nasal consonants (such as /n/ and /m/) with other consonants, requiring precise articulation and airflow control.

    • Clusters with "st" and "sp": Examples include "street," "split," and "spring." These clusters require the coordination of the "s" sound with the following stop consonants (/t/ or /p/), which may take practice to pronounce clearly.

    • Glide: Closing diphthongs involve a smooth glide or transition from one vowel quality to another within the same syllable. The starting point is typically a more open vowel sound, while the ending point is a closer or more closed vowel sound.

    • Duration: Closing diphthongs are relatively longer in duration compared to pure vowel sounds. The transition from the starting to the ending vowel creates a longer overall duration.

    • Articulation: Closing diphthongs involve a change in the articulatory position of the vocal tract. For example, in the English closing diphthong /aɪ/ as in "ride," the sound starts with an open vowel /a/ and glides to a closer vowel /ɪ/ within the same syllable.

    Other examples of closing diphthongs in English include /ɔɪ/ as in "boy" and /eɪ/ as in "say."

    The vowel /ɪ/ in English, as in words like "sit," can vary in its realization depending on the speaker and the phonetic context. In some cases, it may be pronounced with a slightly higher and more close position of the tongue, approaching the sound [i], which is the phonetic symbol for the vowel in words like "see." This variation is called allophony, where different phonetic realizations of a phoneme occur in different contexts.

    Why do we call the English vowels front or central or back vowels? English vowels are classified as front, central, or back based on the position of the tongue in the mouth when producing the vowel sound. This classification system helps us understand the articulatory differences and the placement of the tongue.

    • Front vowels: These vowels are produced with the front part of the tongue raised towards the front of the mouth. Examples include /i/ as in "see" and /e/ as in "bed".
    • Central vowels: These vowels are produced with the tongue in a more central position in the mouth. Examples include /ə/ as in "about" and /ʌ/ as in "cup".
    • Back vowels: These vowels are produced with the back of the tongue raised towards the back of the mouth. Examples include /u/ as in "too" and /ɔ/ as in "thought".

    The classification of vowels into front, central, and back helps us describe and understand the articulatory and acoustic characteristics of vowel sounds in English.

    2.Why is the vowel /ɪ/ sometimes replaced by the "non-phonemic symbol [i]"? The vowel /ɪ/ is the standard representation of the sound in the International Phonetic Alphabet (IPA) for English. However, in certain contexts or dialects, some speakers may pronounce the vowel closer to [i], which is a higher and more fronted vowel.

    The use of [i] instead of /ɪ/ is a transcription convention to represent the phonetic variation observed in some accents or speech patterns. It acknowledges that the actual pronunciation may deviate slightly from the standard /ɪ/ and can be closer to [i].

    It's important to note that the substitution of /ɪ/ with [i] is not a universal phenomenon and may vary among individuals or dialects. It's a way to capture the nuances of pronunciation and highlight the variations that exist in spoken English.

    3.What are the features of closing diphthongs? Closing diphthongs are a type of diphthong where the vowel sound glides or moves from one vowel quality to another, usually towards a closer vowel sound, in the same syllable. The closing diphthongs in English are /ɪə/ as in "ear," /eɪ/ as in "day," /aɪ/ as in "high," and /ɔɪ/ as in "boy."

    The features of closing diphthongs include:

    • Movement: Closing diphthongs involve a continuous movement or glide from one vowel quality to another within the same syllable.
    • Vowel quality: The first element of the diphthong tends to be a more open vowel sound, while the second element is a closer vowel sound.
    • Length: Closing diphthongs are generally longer in duration compared to single vowels.
    • Stress: The stress in a word with a closing diphthong falls on the syllable containing the diphthong.
