Consonants
The standard English consonant system is traditionally considered to comprise 17 obstruents (6 plosives, 2 affricates and 9 fricatives) and 7 sonorants (3 nasals, 2 liquids and 2 semivowel glides).
With the exception of the fricative /h
/, the obstruents are usually classified in pairs as "voiceless and "voiced", although the presence or absence of periodicity in the signal resulting from laryngeal vibration is not a reliable feature distinguishing the two classes. They are better considered "fortis" (strong) and "lenis" (weak), with duration of constriction and intensity of the noise component signalling the distinction.
The six plosives are p b t d k g
:
Symbol Word Transcription p pin pIn b bin bIn t tin tIn d din dIn k kin kIn g give gIvThe "lenis" stops are most reliably voiced intervocalically; aspiration duration following the release in the fortis stops varies considerably with context, being practically absent following /
s
/, and varying with degree of stress syllable-initially.
The two phonemic affricates are tS
and dZ
:
tS chin tSIn dZ gin dZInAs with the lenis stop consonants, /
dZ
/ is most reliably voiced between vowels.
There are nine fricatives, f v T D s z S Z h

The sonorants are three nasals m n N

i: eI aI OI, u: @U aU, 3: A: O: I@ e@ U@
. They are exemplified as follows:
i: ease i:z eI raise reIz aI rise raIz OI noise nOIz u: lose lu:z @U nose n@Uz aU rouse raUz 3: furs f3:z A: stars stA:z O: cause kO:z I@ fears fI@z e@ stairs ste@z U@ cures kjU@zThe vowels /
i:
/ and /u:
/ in unstressed syllables vary in their pronunciation between a close [i]/[u] and a more open [I]/[U]. Therefore it is suggested that /i
/ and /u
/ be used as indeterminacy symbols.

(i) It is possible to transcribe English long vowels without using length marks, thus /i u 3 A O
/. This is phonemically unambiguous, although it does remove the option of restricting the symbols [i u
] to the use just described, for the phonemically indeterminate weak vowels.
(ii) The symbol /E
/ is quite widely used in place of /e
/ for the vowel of "pet".
(iii) In an older notation, now no longer in general use, paired short and long vowels were transcribed using the same vowel symbol with and without length marks, thus /i
/ in "pit", /i:
/ in "ease"; /O
/ in "pot", /O:
/ in "cause".
