Problems of phonostylistics

Backlingual consonants are also called velar, they are produced with the back part of the tongue raised towards the soft palate “velum” /k, g, /
The glottal consonant /h/ is articulated in the glottis.
modifications of consonants Ph mod-ns take place w/in the words which are connected and at their boundaries. All the sounds are prone to change.
Assimilation is the adaptive modification of a consonant by a neighbouring consonant in the speech chain.
Can be:
progressive (a sound is influenced by a preceding sound) ex. Bridge – score
[dζ]→[s]→[ς]
lenis – fortis – fortis
lingular
forelingual
apical
palate-alveolar – alveolar – palate-alveolar
occlusive-constrictive – constr – const noise-noise
bicentral – unicentral – bicentral oral regressive (anticipatory) the sound is influenced by the following sound ten balloons [m]←[n] [b], because [b] is bilabial
Good night – both alveolar, but [d] disappears, because of [n] → g’ night
partial – only one or several distinctive features are modified and sounds become similar (bridge score)
complete – the sound becomes absolutely similar to the influencing sound in all distinctive features (good night)
coalescence – a mutual influence, where two sounds fuse into a sg new onewon’t she? [w∂Ụtςi]
alveolar, occlusive, plosive [t] and palate-alveolar, constrictive [ς] →[tς] – palate-alveolar, a new sound – affricate (occlusive-constr), partial ass-n
Practically in all cases – the change of the place of articulation
Then the manner of articulation:
-loss of plosion (glad to see u);
-nasal (not now)
-lateral (table, at last)
Accommodation is the adaptive modification of V+C or C+V type.
Affects lip position →labialization of consonants: appears under the influence of the neighbouring back vowels: pool, woman
It’s also possible to speak ab the spread lip position of consonants followed or preceded by front vowels [i] – meet and [i:] – team, meat
Such sounds as [r], [tς], [dζ] are pronounced by most speakers w/ rounded lips ever after [i:].
In the casual discourse: in the intervocalic position voiceless cons-ts change their voicing value and become voiced: [t] → [d] (letter)
Elision (zero reduction) is the loss of sounds. Min – in slow, careful speech; max – in rapid, careless speech loss of [h] is widespread
here he is ['iәr i iz] tend to be lost when preceded by [ō] – always [‘ﺭ:wiz]
Alveolar plosives ([t], [d]) are always elided in case the cluster is followed by another consonant:
next day [‘neks ‘dei], just one [‘dζ^s ‘w^n]
there also exist the so-called historical elision
initial cons-s in “wright”, “know”,”knife”
the medial cons-t [t] “fasten”, ‘listen”, “castle”
the ways the sounds are elided in general:
whole syllables – library [‘laibri:]
some words are esp prone to elision:
“of” + cons-t: a cup of tea [k^pә’ti:], going to [gon^], want to [won^]
Liaison – the process of introducing sounds b/w syllables or words to help pronounce them in a more smooth way:
“linking” r: clear [kliә] – clearer [‘kliәrә], teacher of English
“intrusive” r – sometimes appear b/w the vowels. It’s not wanted here, doesn’t exist, but appears in speech to help pronounce more smooth: Ex. the idea [r] of it
When the word-final vowel is a diphthong which glides to [i]: [ai], [ei] the palatal sonorant [j] tends to be inserted: saying [‘sai(j)iη] In case of the u-gliding diph-s: [ou], [au] the bilabial sonorant [w] is smtimes inserted: Ex. do it
All these phenomena manifest the economy of pronouncing effort on the part of the speaker.
Vowels
Vowels are voiced sounds in forming which the airstream passes freely without any obstruction through the larynx the mouth cavity make the vocal cords vibrate. Vowels are classified: in the stability of articulation: (1.l) monothongs - are vowels the articulation of which doesn’t change. The quality of such v-ls is relatively pare [i,e,a:, o:,);, u,3:, ?] ;(1.2) diphthongs in the pronunciation of diphthongs the organs of speech slide from one v-l position to another within one syllable. The nuclear of diphthongs is strong distinct the glide is very weak [ei, эi, au, ?u, є?, u?]. (1.3) In the pronunciation of diphthongs the articulation changes just a little bit.
But the difference between the nuclear the end is not so distinct as it is in the case of diphthongs; [i:, u:]. 
The tongue position: horizontal movement of the tongue. When the tongue is in the front part of the mouth and the front part of it is raised up to the hard palate a front v-1 is pronounced [i:, e].
When the front of the tongue is raised towards to the back part of the lard palate the vowel is called central (or mixed) [ ]. When the tongue is in the back part of the mouth and raised up to the soft palate a back vowel is pronounced [a:, э, э:, u:]. Vertical movement high (or closed) vowels: [i:, u, u:], open (low) vowels [a:, o;]. 
The lip position. When the lips are neutral or spread the vowels are called unrounded.When the lips more or less round they called rounded [u;u].
Vowel length. All Eng. Monophthongs are divided into long[I:, a: u:,?:] and short[I e u a].
