They also differ phonotically from such sounds functioning as vovel in either of two ways.

First, the articuiation may not involve the body of yhe tongue (post-alveoral and labiodentals), theformerthe usual pronunciation in RP at the beginning of 'red', the latter a speech-defective pronunciation of the same sound.

Secondly, where the do invole the body of the tongue, the articulations represent only brief glides to a following vowel: j in yet is a glide starting from the 'i' region and 'w' in 'wet' is a glide starting from the 'u' region

Length of consonants and diphthong:

When RP plosive occur finaily in a syllable their value is determined largely by the lenghth of the syllable which they close. Syllables closed by voicless consonants are shorten than those which are open or closed by a voiced consoant.

When the syllable contains a long vowel or diphthong,

the fully long vowels or diphthongs in robę,

heard (closed by a voiced b,d,g) with the reduced values in ropę,

hurt (closed by a voicless p,t,k). Predicting consonants notably (l,m,n) are

also shrotened by a following (p,t,k) especially when the

consoants are themselves preceded by a short vowel.

Same reduction operates when (p,t,k) occur medialy in a word the length of (al) in rider, writer.

Aspiration of consonant: The voicless series (p,t,k) are fully

aspirated when they appear at the beginning of accented

syllable (pin, tin, kin). When (l,r,w,j) follow (p,t,k) in initial

position the aspiration in manifested in the devocing of (l,r,w,j) -

please, pray, try, clean. Some devoicing may also

occur in relatively unaccounted situations. In other

position preceding a vovel in an unaccented syllable and

finaily such aspiration is relatively weak (p) polite, lip. In absolute postions

i-e preceding silence (p,t,k) may have no audible release.

When a plsoive follows (s) within the same syllable the distinction betwean (p,t,k) on the other hand and (b,d,g) on the other is neutralized (plosives are inspirated).

Nasal release of plosive: When is followed by a homorganic nasal

consonant (syllabic or initial in a following syllable) The

release of air is normaly effected not big a

removal of the orał closure which is retained,

but by the escape of the compressed air though the nasal passage,

opened by the lowering of the soft palate for nasal consonant (p)+(m)

topmost (b)+(m) submerge (t)+(n) chutney (d)+(n) madness.

Some release takes palce when the plosive and homorganic nasal occur at word boundries not now (red nose) different kind of nasalrelease occurs when the nasal consonant following a plosive is not homorganic (bad, man, big nose, big man).

The plosive clousure is not normaly reelased

intil the articulators movements for the nasal consonant.

Approximants: a speech sounds such as glide or

liquid produced by narrowing but not blocking

the vocal tract as by placing on articulator,

such as the tongue, near another part of vocal track (l,w,r)

Homorganic: 2 or morę speech sounds having the same place of articuiation
