The articulatory classification of English vowels

Vowels

rounded
/o,o:,u,u:/

unrounded

/i:,i,e,æ,Λ,α:,ə:,ə/

Multiple Choice

The criteria in which the vowels are classified is

• 
  The position of the lips

• 
  
  The height to which the tongue is raised

• 
  The part of the tongue that is raised

• All of these

According to the

degree of muscular tension

lax

tense

According to the

character of the end

free

checked

Factors influencing the vowel length.

1)The position of a vowel in a word: /si: – si:d – si:t/2)
Word accent: forecast (noun) /´fo:kα:st/

forecast (verb) /fo:´kα:st/

3) The number of syllables in a word:
/ə:/ in ‘verse’ and ‘university’
4) The character of the syllabic structure:
open syllable: ‘her’ /hə:/; closed syllable: ‘earn’ /ə:n/
5) Sonority: /i:/ is longer than /α:/

According to the stability

of articulation

monophthongs
diphthongoids

diphthongs

diphthongoids

Multiple Choice

Vowels that require considerable muscular tension on the part of the tongue are

• 
  Round vowels

• 
  
  Lax vowels

• Front vowels

• Tense Vowels
