Wb eng vowelsintro Presentation Transcript

  • 1. Introduction to English vowels September 2006
  • 2. Description of vowels: HAR
    • Three basic ‘dimensions’: Height, advancement and rounding
      • Height or ‘tongue height’:
        • High, mid, low
      • Advancement or ‘tongue advancement’
        • Front, central, back
      • Rounding or ‘lip rounding’
        • Rounded, unrounded
    • Finer divisions may be useful (more steps)
  • 3. The key (‘point’) vowels [i a u] Real vowels http://www.ling.yale.edu:16080/ling120/Gestural_structure/MRI_Vowels/ Artist’s conception Graphics unavailable. Similar images at : http://www.ling.yale.edu/ling120/Gestural_structure/MRI_Vowels/index.html Graphics unavailable. For similar drawings, see Rogers 2000 p 28 29 30, figures 2.5 2.8 and 2.9
  • 4. Stylized tongue positions
    • Most phonetics books use “artists’ conceptions” of vowel articulation
      • Exaggerate differences of tongue position in oral cavity
      • Miss large differences in pharynx
  • 5. Rogers Vowel Diagrams of GA (p 34)
    • Graphics unavailable
      • See Figures 2.17, 2.18 and 2.19 p 34 of Rogers 2000
  • 6. More X-rays with acoustics
    • Graphics unavailable
    • For related info see http://www.phon.ucl.ac.uk/home/johnm/ball.htm
  • 7. Traditional vowel diagrams
    • The acoustic data based on F1 and F2 resonances are quite similar to traditional vowel diagrams
      • We’ll talk more about F1 and F2 later in course
      • For now I’ll let you hear them
    • But basic descriptive properties are correlated with real physical differences
      • Anyway they’re very useful and the HAR scheme is world standard for descriptive phonetics
  • 8. Rogers’ p. 33 table of GA Vs
    • Graphic unavailable. See text p 33.
    • “ General American”
  • 9. The Simple Vowels of GeneralAmerican (GA)
    • The ‘simple’ vowels
    • Front Central Back*
      • [i] ‘b ea t’ [u] ‘boot’ higher high
      • [I] ‘b i t’ [U] ‘book’ lower high
      • ( [e] ) ( [o] ) higher mid
      • [E] ‘b e t’ [´] ‘sof a’ [ç] ‘bought’ lower mid
      • [√] ‘but’
      • [Q] ‘b a t’ [A] ‘Bob’ (lower) low
      • * Back vowels except [A] are rounded; the rest are unrounded
  • 10. The Simple Vowels W. Canadian (WCE)
    • The ‘simple’ vowels
    • Front Central Back*
      • [i] ‘b ea t’ [u] ‘boot’ higher high
      • [I] ‘b i t’ [U] ‘book’ lower high
      • ( [e] ) ( [o] ) higher mid
      • [E] ‘b e t’ [´] ‘sof a’ lower mid
      • [√] ‘but’
      • [Å] (higher) low
      • [Q] ‘b a t’ ‘B o b, b ou ght’ (lower) low
      • *All back vowels including [Å] are rounded; the rest are unrounded
      • Note: The ‘official’ IPA description of /ʌ/ is a lower mid back unrounded vowel, but it we will call it a central vowel,
      • since that is how the vowel symbol is used in English. (Strict IPA would have us use the symbol / ɐ/ for the vowel in ʼbutʼ.)
  • 11. Diphthongs of GA (and WCE)
    • The ‘simple’ vowels
    • Front Central Back
      • [ej] ‘b ai t’ [ow] ‘boat ’ (higher) mid
      • [aj] ‘t i de’ [aw] ‘l ou d’ low
  • 12. Variations on transcribing second part of diphthongs
    • Vowel in ‘hide’ variously transcribed
    • [aj ] [aI] [a j ] [a iª ]
    • They all mean pretty much the same thing
    • We’ll use Roger’s convention
      • I may slip up and use [aI]
  • 13. The low back vowel in W. Cdn
    • Rogers’ p. 124 uses [ A ] for Cdn vowel in ‘Bob’ or ‘bought’
      • But he notes variation
      • Local pronunciation seems closer to [ Å ]
      • You can choose either symbol for broad transcription
        • I may vary on board
  • 14. Next couple of weeks…
    • We’ll be concentrating on consonant sounds
    • Transcription part of first quiz will include broad transcription of all English consonants
    • Only the three ‘point vowels’ [i A u]
