Vowel Articulation and Classification Study Notes

Articulation of Vowels

  • Position of the Tongue in Producing Bells:
    • Forward Tongue Position:
    • Refers to producing sounds where the highest part of the tongue is positioned toward the front of the mouth.
    • Neutral Position:
    • Tongue is neither fully forward nor back, which can influence how sounds are articulated.

Vowel Classification

  • Labeling Vowels:
    • Vowels are labeled based on four characteristics.
    • Height: Refers to how high the tongue is in the mouth during the articulation of the vowel.
    • Advancement: Refers to how far forward the tongue is positioned.
    • Tense vs. Lax:
      • Tense vowels are characterized by a longer duration and more muscular tension compared to lax vowels.
      • Example:
      • E (tense): Stressed, longer duration, produced with greater tension.
      • I (lax): Non-stressed, shorter duration, produced with lesser tension.
    • Roundness: Refers to whether the lips are rounded or unrounded during articulation.
      • Example:
      • The vowel 'e' is unrounded while vowels like 'o' are usually rounded.

Specific Vowel Analysis

  • Vowel 'E':

    • Characteristics:
    • Height: High
    • Advancement: Front
    • Tense/Lax: Tense
    • Roundness: Unrounded
    • Articulation Example:
      • Make the sound of 'E' while following lips' position.
    • Mnemonic for 'E':
    • "Are you blowing me a kiss?" - to remember lip positioning.

  • Vowel 'I':

    • Characteristics:
    • Height: High
    • Advancement: Front
    • Tense/Lax: Lax
    • Roundness: Unrounded
    • Usage in Context:
      • Commonly appears in closed syllables (e.g., "sing") or before certain consonants.

  • Vowel 'A':

    • Characteristics:
    • Discussed but not elaborated further in the transcript.

Diphthongs

  • Definition of Diphthongs:

    • Two vowel sounds that combine to form one phoneme.
    • Articulation involves a glide from the first vowel (onglide) to the second vowel (offglide) continuously.

  • Elements of Diphthongs:

    • Onglide: The first element in a diphthong.
    • Offglide: The second element in a diphthong.
    • Tongue Motion:
    • As the articulation moves, the tongue typically rises in the oral cavity.

  • Examples of Diphthongs:
