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