Principles of classification:
The presence or absence of obstruction.
The distribution of muscular tension.
The force of the air stream coming from the lungs.

The main peculiarities of the English articulation basis
The tongue is broadened,
                                                            
                                    flattened, the tip is slightly drawn back from the teeth.
Lips are neutral, slightly spread, the upper lip is tense.

Bilingualism – the practice of alternate use of two languages
                                                            
                                    by a person in communication.
Language interference – a process and a result of interaction and mutual influence of the language systems which are in contact.
Phonetic interference – the deviation from the phonetic norms of the language.

Prosodic interference involves the use of wrong prosodic patterns:
The use
                                                            
                                    of falling tones instead of rising ones.
E.g. Shut the door behind you!
    Good bye!
The choice of the wrong pitch, stress or rhythmic pattern.

All the short vowels are characterized as lax.

The vowel length may depend on:
1) The position of a vowel in a word.
In the terminal position a vowel is the longest, it shortens before a voiced consonant, it is the shortest before a voiceless consonant. E.g. /si: - si:d – si:t/

Length
2) Word accent.
The vowel is longer
                                                            
                                    in an accented syllable that in an unaccented one.
E.g. forecast (noun) /'fɔ:kɑ:st/
	forecast (verb) /fɔ:'kɑ:st/ 
3) The number of syllables in a word.
Similar vowels are shorter in a polysyllabic word. Thus, /ə:/ in the word verse is longer that in the word university.

4) The character of the syllabic
                                                            
                                    structure:
open syllable: ‘her’ /hə:/; closed syllable: ‘earn’ /ə:n/. 
5) Sonority (звучность): /i:/ is longer than /α:/.

According to the stability of articulation
                                                            
                                    English vowels are divided into:
1) monophthongs, or simple vowels;
2) diphthongs, or complex vowels;
3) diphthongoids, or diphthongized vowels.

The quality of a monophthong is
                                                            
                                    not changed throughout the whole duration of the vowel.
During the pronunciation of a diphthong the tongue and the lips move from one vowel position to another within the syllable. So, there are two vowel elements in a diphthong: the nucleus and the glide.

All English diphthongs are falling (nucleus+glide).
                                                            
                                    A falling diphthong begins with the nucleus, its stronger and longer element, and ends in a glide, which is weak and short. 
A rising diphthong begins with a glide and ends in a nucleus (glide+nucleus). Such diphthongs are common in Italian, Spanish, etc.

A diphthongoid is a vowel sound
                                                            
                                    intermediate (промежуточный) in character between a monophthong and a diphthong. The elements of a diphthongoid are close to each other: /i:/, /u:/

Frequency – the number of vibrations
                                                            
                                    per second.
Intensity – variations in the loudness of the sound.
Duration – the quantity of time during which the same vibratory motion is produced.
