Vowel sounds. Principles of classifica
tion
Vowels
Sounds of speech, during the articulation of which the air flow passes
freely through the pharyngeal and oral cavity, and the vocal cords are
shifted and vibrate, are called vowels. Vowels are sounds produced
by the voice (tone).
The Principles of classification
Principles
Stability of
articulation
The position
of the lips
The position
of the tongue
The Length
of the vowels
 The degree of
tenseness and
character of the
vowel end
diphthongoids
Vowel sounds having slightly changing articulation:
[i:], [u:]
diphthongs
The complex sounds consisting of two elements
(nucleus and glide):
narrow [eɪ, əʊ, ɪə, eə, ʊə]
wide [aɪ, aʊ, ɔɪ]
The stability of articulation
monophthongs
They are pure vowels, the articulation is almost
unchanging: [ɪ, e, ӕ, a :, ɒ, ɔ :, ʊ, ʌ, ɜ :, ə]
The position of the tongue
Vowels
(according to the horizontal movements of the tongue)
front central back
Vowels
(according to the vertical movements of the tongue)
high mid low
front
/i:, e, æ/ /eı, ε∂, aı/
front-retracted /ı/ /ı∂/
Vowels
mixed or central /∂, ɜ:/
back-advanced
/ʌ, u, a:/ /ou, u∂/
back
/o, o:, u:/ /oı/
narrow /i:, u:/
high (close)
broad /ı, u/
narrow
/e, ɜ:, ou/
mid (half open)
broad /∂/ /ε∂/
Vowels
narrow /ʌ, o:/
low (open)
broad/æ, a:, ɔ, aı, au /
It refers to how high or low our tongue is. Thus we
can say that /i/ is a high vowel sound, /e/ is
intermediate, and /a/ is low. You may notice the
movement of the tongue if you pronounce these
[ ɒ, ɔ :, ʊ, u:] [i:, ɪ, e, ӕ, a :, ʌ, ɜ :, ə]
The position of the lips
Vowels
Rounded Unrounded
[i:, a :, ɜ :, ɔ :, u:] [ɪ, e, ӕ, ʌ, ə, ɒ, ʊ]
The length of the vowels
Vowel
Long Short
The degree of tenseness and the character of the end of a vowel
According to the
degree of muscular tension
tense lax
According to the
character of the end
free checked
The degree of muscular tension & the
character of the vowel end
[i:, a :, ɜ :,
ɔ :, u:, eɪ,
əʊ, ɪə,
eə, ʊə,
aɪ, aʊ, ɔɪ]
[ɪ, e, ӕ,
ʌ, ə, ɒ,
ʊ]
monophtho
ngs,
diphthongoi
ds,
diphthongs
stressed
and
unstressed
short
vowels
under stress
followed by
a consonant
Tense
