  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."

    English vowels are categorized as front, central, or back based on the horizontal position of the tongue in the mouth during their production. This classification is related to the location of the highest point of the tongue.

    1. Front vowels: These vowels are produced with the highest point of the tongue positioned toward the front of the mouth, closer to the front teeth. Examples include /i/ as in "see" and /e/ as in "set."

    2. Central vowels: These vowels are produced with the highest point of the tongue positioned in the central part of the mouth. An example is /ə/ as in the unstressed "a" in "about."

    3. Back vowels: These vowels are produced with the highest point of the tongue positioned toward the back of the mouth, closer to the soft palate. Examples include /u/ as in "too" and /ɑ/ as in "car."

    The vowel /ɪ/ is sometimes replaced by the non-phonemic symbol [i] in certain contexts or dialects. This is because there can be variation in the pronunciation of /ɪ/ depending on factors such as stress, regional accents, and speech tempo. In some accents or speech patterns, /ɪ/ may be pronounced closer to [i], which is a higher and more tense vowel. This variation is considered non-phonemic because it does not distinguish meaning in English words.

    Closing diphthongs are a type of diphthong where the second element or glide is higher or closer in position to the starting vowel. The features of closing diphthongs include:

    1. Movement: Closing diphthongs involve a smooth gliding movement from the starting vowel to a higher or closer position.

    2. Tenseness: Closing diphthongs are typically tense or longer in duration compared to opening diphthongs.

    3. Vowel quality: The second element of closing diphthongs is usually a high vowel, such as /ɪ/ as in "ride" or /ʊ/ as in "loud." The starting vowel can vary depending on the specific diphthong, such as /aɪ/ as in "light" or /eɪ/ as in "day."

    Examples of closing diphthongs in English include /aɪ/ as in "ride," /ɔɪ/ as in "boy," and /eɪ/ as in "day."
