This article deals with the problem of the phonetic phenomenon of assimilation in the 
English language. The work examines the definitions of assimilation, its types and methods of 
its formation, affecting the place of formation of the barrier. 
Key words: assimilation, dissimilation, reduction, stress. 
Currently, the study of foreign languages is essential. In connection with the 
development and expansion of international relations, the study of foreign languages is an 
important component. One of the sides in learning a language is knowledge of phonetics, 
which is based on the correct assimilation of sounds. 
In the speech sound waves, sounds can influence each other, which is caused by 
combinatorial changes, which include accommodation, assimilation, dissimilation, dieresis, 
epenthesis, haplology. In addition, the general conditions of pronunciation can influence the 
sounds. This causes positional changes in sounds, which include a prosthesis at the beginning

of a word, becoming voiceless of voiced consonants at the end of a word, reduction of 
unstressed vowels, etc. 
There are combinatorial changes in sounds. One of these changes is accommodation, 
which occurs when consonants and vowels are adjusted next to each other. There are two 
types of it: progressive and regressive. In any case, this is a partial adaptation of sounds. In 
different ways in different languages and even in one language at different periods of its 
existence, the question of what accommodates: consonants to vowels or vowels to consonants 
is resolved. 
Assimilation is the process of assimilating sounds of the same kind. It can be complete 
or incomplete; progressive or regressive, contact or distant. Assimilation can affect one or 
another feature of sound. For vowels, these are signs of a place of articulation,rising, 
labialization, and for consonants, it is a way and a place for the formation of tence and lax; 
participation - non-participation of the voice (voiceless and voiced). Also, assimilation can be 
characterized from all these points of view [3; 43]. 
Dissimilation is the process of assimilation of sounds of the same type, when two different or 
similar sounds are obtained from two identical or similar sounds. Cases of dissimilation 
concern both consonants and vowels; can be contact and distant; progressive and regressive 
[8; 48]. 
Also in the English language, there are positional changes associated primarily with 
stress, that is, with the position of the syllable relative to stress. 
Stress is the selection of one syllable from a group of syllables. It is achieved in 
different languages by various means, namely: the length of pronunciation - quantitative 
(quantitative or longitudinal) stress; strength or intensity of articulation - dynamic (or power, 
expiratory) stress; the movement of the voice tone (ascending, descending or combined) 
against the background of the neutral tone of other syllables - tone (melodic, musical) stress. 
These techniques can be performed both separately and combined with each other. 
There are the following types of stress: fixed and non-fixed; single and mixed. 
Reduction is a weakening and change in the sound of unstressed syllables and, above 
all, the syllable sounds of these syllables. In this regard, it concerns mainly vowel sounds. 
Distinguish between quantitative and qualitative reduction. The source of the reduction is 
dynamic and dynamically complex stress [1; 46]. 
However, positional changes are characteristic of consonants. These are positional 
changes of noisy consonants at the end of a word, when the voiced changes to voiceless. This 
phenomenon is a consonant reduction. 
Assimilation can affect all the articulatory features of a consonant, or only some of 
them, i.e. we can talk about assimilation affecting: 
• the place of formation of the obstruction or the type of obstruction and the active organ of 
speech; 
• method of noise production; 
• the work of the vocal cords; 
• position of the lips [8; 170]. 
Assimilation, affecting the place of the formation of the obstruction, occurs when the 
main (alveolar) variants of the phonemes [t], [d], [n], [l], [s], [z] are changed to minor 
(dental), when they adjacent to dental consonants, for example, tenth, in them, width, read 
this, sixth. 
Assimilation, affecting the place of formation of the obstruction and the active organ 
of speech, is observed in words with the prefix con -: when it is followed by consonant 
phonemes [k], [g] the alveolar sonant [n] changes to the backlingual [ŋ], if the prefix is 
primary or secondary stress: congress
