8. Principles of Consonant classification.

the work of the vocal cords and the force of exhalation: voiced (when the vocal cords are draw together & vibrate-b, d, g, z, v, 3, m, θ, n, 1, r, j, w, d3) and voiceless(when the vocal cords are taken a part & don’t vibrate- p, t, k, s, f, ð, h, t, 3). The force of exhalation and the degree of muscular tension are greater -> voiceless consonants-“fortis”. Voiced-“lenis

the position of the active organ: 1) labial, 2) lingual, 3) glottal.

1. Labial: a) bilabial and b) labio-dental. Bilabial with both lips: /p, b, m, w/. Labio-dental with the lower lip against the edge of the upper teeth: /f, v/.

2.Lingual: a) forelingual, b) mediolingual and c) backlingual.

Forelingual [s,z, ʃ. Ʒ] with the tip of the tongue. the position of the tip of the tongue: dosal, apical, cacuminal

Mediolingual- palatal with the front part of the tongue. [r,j] with the front part of the tongue raised high to the hard palate.

Backlingual [k, g]-velar, with the back part of the tongue raised towards the soft palate /k, g

3.The glottal consonant /h/ is articulated in the glottis.

to the manner of noise production from the closure: 1) complete closure -> occlusive consonants (1. noise /p, b, t, d, k, g/ and 2. sonorants /m, n, ŋ / ); 2) incomplete closure -> constrictive consonants 1. noise /f, v , h, s, z , Ʒ/ and 2. sonorants / w, j, l, r/; 3)   the combination of the two closures, then occlusive-constrictive, or affricates, are produced / ʧ, ʤ /.

the position of the soft palate: oral and nasal. soft palate is raised, the air to the pharynx to the mouth cavity, oral : /p, t, k, f, v/ etc. soft palate is lowered, the air to the nasal cavity, nasal: /m, n, ŋ/.

10. Differences in the Articulation Bases of the English and Russian Consonants. Typical mistakes of Russian learners.

Eng - the tip of the tongue is near of the teeth ridge, Rus - to the upper front teeth.

Eng forelingual (s, z, ʃ, Ʒ) the tip occupy apical, cacuminal & retroflexed position. the tip is against the teeth ridge the forelingual apical sounds: [t-d, n, s-z, ʃ-th, t ʃ- ʤ] the tip is curled behind the backslope of the teeth ridge the forelingual cacuminal [r]. The tip is curled still further the American retroflexed [r].

The tip in the articulation of the Rus forelingual cons occupies dental position: [т-д,з-с,ц,н].

In the articulation of the Eng [θ] &[ ð] the tip between the upper & the lower teeth.

The tip Rus alveolar rolled cons [p] vibrates in the flow of air out of the month cavity & interrupts repeatedly -> obstruction against the teeth ridge.

[h] - the air passes through the larynxes & glottis, the back wall of the pharynx contracts simultaneously with the slight movement of the root of the tongue to the pharynx.

Rus [x] the back part of the tongue is raised to the soft part palate, Rus learners use [x]=[h].

Eng [ŋ] the soft palate makes a complete obstruction with the back part of the tongue & the flow of air to the nasal The Russian forelingual [н] for Eng back lingual [ŋ]
