Consonants: Principles of Classification

Unlike vowels consonants are produced with an obstruction to the air-stream in the mouth or nasal cavities. That is why they are characterized by a certain degree of noise. The organs of speech are tense at the place of obstruction.

To differentiate the 24 consonants from each other, phoneticians use a classification based on the following principles:

I) degree of noise, II) manner of articulation, III) place of articulation.

I.According to the first principle all English consonants are divided into two big classes – noise consonants and sonorants. In their turn noise consonants vary 1) in the work of the vocal cords (voiced/voiceless) and 2) in the degree of force of articulation (lenis/weak, fortis/strong).

II. We need to know how the sound is made, i.e. the manner of articulation. It is determined by the type of obstruction. According to this principle the English consonants fall into 3 groups: occlusive; constrictive; occlusive-constrictive (affricates). Occlusive sounds are produced when the air stream meets a complete obstruction in the mouth (the organs of speech are in contact). The sounds of this type are also called stops because the breath is completely stopped at some point of articulation and then it is released with a slight explosion (that is why they are also called plosives). Constrictive fricativeconsonants are those in the production of which the air stream meets an incomplete obstruction in the resonator (the air passage is constricted and escapes through the narrowing with friction). Occlusive-constrictive(or affricates) are noise consonant sounds produced with a complete obstruction, which is slowly released, and the air escapes from the mouth with some friction.

III. We also need to know where in the vocal tract the sound is made (i.e. its place of articulation) and which vocal organs are involved. The place of articulation is determined by the position of the active organ of speech against the point of articulation. There may be one place of articulation (focus), or two (foci), when active organs of speech are in contact with two points of articulation. The sounds of the first type are called unicentral, of the second type - bicentral.

According to this principle the English consonants are divided into labial, lingual and glottal.

Labial sounds are produced when both lips are active (bilabial) or with the lower lip against the edge of the upper teeth (labio-dental).

Lingualsounds are classified into:

1) forelingual, which are made with the tip or the blade of the tongue against the teeth ridge or the teeth correspondingly (*remember apical or dorsal articulation - the latter is not typical of English), or with the tip of the tongue at the back part of the teeth ridge (cacuminal articulation).

According to the place of obstruction forelingual consonants may also be divided into: a) interdental (made with the tip of the tongue projected between the teeth); b) dental (produced with the blade of the tongue against the upper teeth); c) alveolar (articulated with the tip against the upper teeth ridge); d) post-alveolar (made with the tip/blade of the tongue against the back part of the teeth ridge or behind it); e) palato-alveolar (the tip/blade of the tongue is against the teeth ridge and the front part of the tongue is raised towards the hard palate, thus having 2 foci);

2) mediolingual; produced with the front part of the tongue. They are always palatal, i. e. made with the front part of the tongue raised high to the hard palate;

3) backlingual (= velar), produced with the back part of the tongue raised towards the soft palate.

Theglottal sound is articulated in the glottis.

Section 2 [ p ]

(occlusive, plosive, bilabial, strong/fortis, voiceless)

I. Practise the articulation of the sound [ p ]. Observe the necessary degree of

aspiration, loss of plosion, nasal / lateral plosions, and correct pronunciation of

the combinations [ pl ], [pr].

peace speak except happen please present stop looking

part sport stopped halfpenny place practice cheap book

pair spell hope to shopman plan prize stoop down

post spade ripe corn stop me plant prove sharp remark

pan spoon stop please top meeting plot proud help me

II. Read the sentences. Follow the tonetic marks.

1. Present company excepted. О присутствующих не говорят.

2. Keep up appearances. Соблюдайте приличия.

3. Pat’s a perfect paragon. Пэт – образец для подражания.

4. Percy’s as proud as a peacock. Перси очень горд.

5. Poll’s as plump as a partridge. Полли пухленькая.

6. Peg’s as pretty as a picture. Пег прехорошенькая.

7. Stop playing Pantaloon. Не валяй дурака.

8. They pulled Paul to pieces. Они раскритиковали Поля в пух и прах.

III. Match the following English idioms, proverbs and sayings with their Russian

equivalents. Make up situations to illustrate their usage.

1. open a new chapter a. неуместный, лишний

2. out of place b. нарочно, преднамеренно

3. plenty is no plague c. подвергнуть испытанию

4. put to the proof d. кашу маслом не испортишь

5. on purpose e. познакомиться с кем-л.

6. pick up with smb f. начать новую жизнь

IV. Pronounce the tongue twister in the quickest possible way. Observe the correct

articulation of [ pl ].

A pleasant place to place a plaice is a place where a plaice is pleased to be placed.

Listen to the dialogue and learn it by heart.

Passports, please

Mr and Mr. Tupman are at the airport. They have just got off the plane from Paris.

Official: Passports, please!

Mrs. Tupman: I think I’ve lost the passports, Poppy.

Mr. Tupman: How stupid of you, Peter! Didn’t you put them in your pocket?

Mr. Tupman: (emptying his pockets) Here’s a pen … a pencil… my pipe… a

postcard… an envelope… a stamp… a pin…

Mrs. Tupman: Oh, stop taking things out of your pockets. Perhaps you put them

in the plastic bag.

Mr. Tupman: (emptying the plastic bag) Here’s a newspaper… an apple… a

pear… plastic cup… a spoon… some paper plates… a piece of

pork pie… a pepper pot…

Mrs. Tupman: Oh, stop pulling things out of the plastic bag, Peter. These people

are getting impatient.

Mr. Tupman: Well, help me, Poppy.

Mrs. Tupman: We’ve lost our passports. Perhaps we dropped them on the plane.

Official: Then let the other passengers past, please.

Mr. Tupman: Poppy, why don’t you help? You aren’t being very helpful. Put

the things in the plastic bag.

Official: Your name, please?

Mr. Tupman: Tupman.

Official: Please go upstairs with this policeman, Mr. Tupman.
