In this lesson, you’ll learn the correct mouth position, hear the difference between the AW and AH vowels, and discover how the sound changes before R.
What Is the AW [ɔ] Vowel?
The AW as in LAW vowel is a common sound in American English, but it can be confusing because it closely resembles the AH as in FATHER vowel.
In some American accents, speakers even replace the AW sound with AH in certain words.
Understanding how the AW vowel is formed will help you pronounce words more naturally and improve your listening skills.
Mouth Position for the AW Vowel
To pronounce the AW vowel correctly:
- Drop your jaw.
- Pull the tongue back.
- Keep the tip of the tongue from touching anything.
- Let your lips flare slightly outward.
Rachel also shares a helpful tip: gently bring your cheeks inward and slightly forward to distinguish the AW vowel from the more relaxed AH vowel.
Practicing this mouth position makes the sound clearer and more consistent.
AW vs. AH: What’s the Difference?
The AW and AH vowels are very similar, but they are not produced exactly the same way.
AW [ɔ]
- Lips flare slightly
- Tongue pulls farther back
- Cheeks engage slightly
AH [ɑ]
- Lips stay relaxed
- Tongue remains lower and more relaxed
- Less facial movement overall
Learning this distinction helps you hear and produce the correct vowel in everyday speech.
Stressed vs. Unstressed AW
Like other American English vowels, the AW sound changes depending on sentence stress.
Stressed AW
A stressed AW vowel is:
- Longer
- Louder
- Higher in pitch
- More fully articulated
Example:
- saw
Unstressed AW
In unstressed syllables, the vowel becomes:
- Shorter
- Quieter
- Flatter
- Less fully formed
For example, the function word on is often pronounced with a very quick AW sound in connected speech.
Understanding this difference helps your speech sound more natural and improves your listening comprehension.
How AW Changes Before R
When the AW vowel is followed by an R, the pronunciation changes.
Examples include:
- core
- sore
- quarter
Instead of producing a pure AW vowel, your mouth begins moving toward the American R position.
You’ll notice:
- More lip rounding
- Less jaw drop
- The tongue pulls farther back and slightly upward
This blending creates the unique AW + R sound heard in many American English words.
Practice Words with the AW Vowel
The lesson includes repetition practice with common vocabulary, such as:
- boss
- long
- runoff
- lifelong
- login
- wrong
- daughter
Practicing these words helps reinforce both pronunciation and listening skills.
Tips for Better Pronunciation
As you practice the AW vowel:
- Keep your jaw relaxed and open.
- Let the tongue move back naturally.
- Avoid making the vowel identical to AH unless your target accent uses that pronunciation.
- Pay attention to stress—stressed and unstressed vowels sound different.
- Notice how the vowel changes before an R.
Small adjustments in mouth position can make a noticeable difference in your pronunciation.
