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.

/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.

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.
