Week 12 Lecture - Vowels

Week 12 Lecture: Difficult Vowels

Vowel Recap

  • Vowels allow air to pass through the speech tract freely while vocal cords vibrate.

  • Ways to describe vowels:

    • Length: short vs. long

    • Monophthong (single sound) vs. diphthong (combination of sounds)

    • Tongue position: front vs. back

    • Mouth openness: close vs. open

Representing Vowel Features

  • A vowel chart illustrates features such as:

    • Backness (front-back)

    • Height (close-open)

    • Lip-rounding

  • Positions of vowels on the chart indicate they can be easily confused if similar.

  • Different charts can represent different languages and dialects.

Challenges in Learning Vowels

  • Vowel representations are often more continuous than consonants, which are more categorical.

  • English orthography is inconsistent, especially with vowels.

  • Significant variation in vowel pronunciation across English dialects compared to consonants.

Diagnosing Vowel Difficulties

  • Individual vowel difficulties are influenced by L1 background.

  • Suggested tests from CEP Chapter 34:

    • Test 1: Words in isolation

    • Test 2: Words in paragraph context

  • Recommendations for practice: work with peers and record yourself reading chapters.

The Dock & Duck Vowels

Spelling

  • /ɒ/: often spelled with "o"—examples: dock, boss, lot, honest.

  • /ʌ/: often spelled with "u"—examples: duck, bus, cup, some (note: not put!).

Pronunciation

  • Both vowels are short monophthongs

  • Height: both are open-mid (tongue midway)

    • /ɒ/: more open, especially in American English

    • /ʌ/: more centralized to near-back

  • Lip-rounding:

    • /ɒ/: rounded

    • /ʌ/: unrounded

Pronunciation Practice with Minimal Pairs

  • Pair examples: got/gut, dock/duck, boss/bus, etc.

The Look & Luke Vowels

Spelling

  • Both sounds can be spelled with "oo", "ou", or "u".

  • Words with /ʊ/: look, good, woman.

  • Words with /uː/: pool, fool, group, Luke.

Pronunciation

  • Both are monophthongs:

    • /ʊ/: short

    • /uː/: long

  • Height:

    • /ʊ/: near-close

    • /uː/: close

  • Backness:

    • /ʊ/: near-back

    • /uː/: back

  • Lip-rounding: both are rounded, /ʊ/ is more lax.

Pronunciation Practice with Minimal Pairs

  • Pair examples: look/Luke, good/gooed, pull/pool.

The Pan & Pen Vowels

Spelling

  • /æ/: usually spelled with "a"—examples: pan, jam, had.

  • Exceptions include: calm, father.

  • /ɛ/: usually spelled with "e"—examples: pen, desk, fell, friend.

  • Exceptions include: said, any, bury.

Pronunciation

  • Both are short monophthongs and unrounded.

  • Duration:

    • /æ/: longer

    • /ɛ/: shorter

  • Height:

    • /æ/: near-open

    • /ɛ/: open-mid

  • Backness: both are front vowels.

Pronunciation Practice with Minimal Pairs

  • Pair examples: bat/bet, bag/beg, man/men.

Exam-Type Questions

  • Reasons why vowels are challenging for learners of English?

  • Example of a minimal pair illustrating a vowel contrast (e.g., /ɒ/ vs. /ʌ/).

  • Advice for pronouncing /æ/ and distinguishing "pan" from "pen."

  • Describe sounds in terms of length, monophthong/diphthong, height, backness, and lip rounding.

Pronunciation Analysis Assignment

  • Analyze an audio recording based on CEP Task 1.1:

    • Read-aloud speech or spontaneous speech.

  • Written analysis (500 words) focusing on pronunciation improvements.

    • Identify significant issues and explain corrections using linguistic terminology.

  • Include a second audio recording demonstrating corrected pronunciation.
