The Simple Vowels
The Schwa Vowel
To Produce: Keep your tongue relaxed in a central position. The lips remain neutral.
The schwa is the shortest, the most simle, and the most frequent sound in English speech. The schwa vowel regquires no movement of the tongue, the jaw, or the lipbs; and there is no visible face movement. The sound is felt onlyat the larynx as a short, voiced sound.
There are two versions of the schwa: one stressed and the one unstressed.
The Stressed Schwa /ʌ/
- -- - -- - --
but/butt bud cup cub hunt hum
Notice how the consonant after the vowel affects the vowel's length.
Practice the stressed schwa. Repeat:
- -- - --
mutt mud nut non/nun
tuck tug runt run
The Unstressed Schwa /ə/
This sound is used in unstressed syllables. The following words contain both the stressed and the unstressed schwa. Listen:
above sudden trouble
Repeat these words:
