22. The phoneme. The system of English phonemes

24. The system of English vowels and consonants

The phoneme is a minimal abstract linguistic unit realized in speech in the form of speech sounds. The phoneme is the smallest contrastive language unit which may produce a change of meaning. It's functional unit, i.e. it is capable of differentiation of the meaning, E.g. pie -tie

1. The system of consonant phonemes.

According to Vasiliev the classification is built on the type of obstruction and manner of production of the noise hence: 1.occlusive (in the production of which a complete obstruction is formed), 2. constrictive (an incomplete obstruction is formed)

The other classification: 1.Degree of voicing (- Voiced [b], [z], [v] etc. - Voiceless [p], [s], [f] etc.); 2. Place of articulation (- Labial (labial - labio-dental - bilabial),

- Lingual (forelingual - medialingual - backlingual), - Glottal); 3.Manner of articulation (3.1. occlusive vs. constrictive pine -fine, bat - that, bee – thee, 3.2.constrictive vs. affricates fare — chair, fail -jail, 3.3. constrictive unicentral vs. constrictive bicentral same — shame); 4.According to the force of articulation (-weak (lenis), - strong (fortis)); 5.Position of the soft palate (- oral, - nasal)

2. The system of vowel phonemes.

1. According to the stability of articulation vowels subdivided into: (1. Monophthongs (the articulation of the sounds is almost unchanging). 2.Diphthongs (the organs of speech glide from one vowel position to another within one syllable. The starting point is strong and distinct. The Glide is very weak. Diphthongs consist of two perceptible vowel elements). 3 Diphthongoids (the difference between the starting point and the end is not so distinct. There are two of them: [i:] and [u:])

2.According to the position of the tongue:

Horizontal movement:(1.Front (the tongue is in the front part of the mouth and its front part is .raised, [ᴂ], [e], [i:] etc.) 2. Front retracted (the tongue is the front part of the mouth but slightly retracted. [I]) 3. Central (the front part of the tongue is raised towards the back part of hard palate.[Ʌ], [ə:]) 4. Back (the tongue is in the back part of the mouth, its back part is raised to soft palate, [o:], [u:]) 5 Back advanced (the tongue is in the back part of the mouth, it is slightly advanced, and its central part is raised to the front part of the soft palate, [u])

The vertical movement: 1. Close: 1. narrow [u:], [i:]; 2.broad [I], [u], [Iə], [uə]

2. Mid: 1. narrow [e], [ə], [eI], [eu]; 2. broad [Ʌ], 3. Open: 1. narrow [еə], [о:], [oI]

According to the position of the lips: (Spread; Neutral; Rounded (unrounded)

Vowel tenseness (Tenseness characterizes the state of the organs of speech at the moment of vowel production): (Long: [i:], [u:], [а:], [о:], [з:]; Short [I], [Ʌ], [о], [u])

Qualitative difference is the main relevant feature that serves to differentiate long and short vowel phonemes depend on the position they occupy in a word.
