2. Nasal plosion

At the junction of the plosive consonants [t, d, p, b, k, g] with the nasal sonorants [m, n] the articulation of the sonorant starts when the articulation of the plosive consonant is not yet finished. As a result, instead of removing the obstruction in the mouth cavity, the air stream passes through the nasal cavity producing the effect of a nasal plosion.

Eg. – shouldn’t, wouldn’t, meet my friend.

3. Lateral plosion

At the junction of a plosive consonant with the lateral sonorant [1] the plosion is produced during the pronunciation of the sonorant as the air stream passes along the sides of the tongue, lowered for the ar­ticulation of [1]. This phenomenon is known as lateral plosion:

e.g.: place, blow, glance, kettle, I'd like to see you tomorrow.

4. Loss of Aspiration.

English voiceless plosive consonants [p, t, k] are pronounced without aspiration in the position after fricative [s].

Eg.: spider, stone, sky

5. Combinations of plosive and fricative consonants

When a plosive consonant precedes a fricative consonant within a word or at a syllable or word boundary (juncture) it has its release during the pronunciation of the fricative. This phenomenon is the result of close co-articulation of adjacent consonants in English and is called fricative plosion (release):

e. g.: let's, what's, kinds, upside, stops, walks.

6. Alveolar consonants before [θ, ð]

At the juncture of the alveolar consonants [t, d, n, 1, s, z] and the interdental consonants [θ, ð] regressive assimilation affecting the place of articulation is observed: the alveolar consonants are represented by their dental variants (allophones).

Eg.: ninth, sixteenth, about the text.

7. Combinations of consonants with [w]

Consonants preceding [w], especially in a stressed syllable, are lip-rounded (labialized), i.e. regressive assimilation affecting the position of lips takes place.

Eg.: twist, quarter, switch, dweller.

When the sonorant [w] is preceded by a voiceless consonant there is also some devoicing of the sonorant (progressive assimilation effecting the work of the vocal cords). The devoicing is especially strong after [t, k] in a stressed syllable and is weaker in unstressed syllables and at a syllable or word boundary. Thus in the clusters [tw, kw, sw] double (reciprocal) assimilation takes place.

Eg.: twenty, quiet, sweet

7. Linking [r]

When a word ending in [ə] (including [Iə], [еə], etc.), [ɑ:], [ɔ:] or [з:] is immediately followed by a word beginning with a vowel, the sound [r] is very often inserted at the end of the first word joining it to the next one.

When the spelling of the word ends in the letter "r" (or "-re"), the inserted г-sound is called the linking [r]. When there is no "r" in spelling, the inserted r-sound is called the intrusive [r] (e.g., the idea [r] of it).

Learners of English are generally not recommended to use the intrusive [r], while the linking [r] is recognized as a typical feature of the English Standard pronunciation. Notice, however, the absence of linking [r] in such "inconvenient" word sequences as 'a roar of laughter', 'an error of judgment'.
