Organs of speech are: nasal cavity (полость носа), lips, teeth, alveolar ridge, ‘larynx(гортань), palate (soft and hard), uvula(язычок), tongue (tip, blade(передняя часть), front, back), epiglottis(надгортанник), pharynx(глотка), vocal cords, and tra’chea(трахея).
The air stream released by the lungs goes through the windpipe (дыхательное горло) and comes to the larynx, which contains the vocal cords. The vocal cords are two elastic folds (изгибы) which may be kept apart or brought together (сведены вместе). The opening between them is called the glottis (голосовая щель). If the tense(напряженный) vocal cords are brought together, the air stream forcing an opening makes them vibrate and we hear some voice.
A short interval of silence, an intermission arising from doubt Of uncertainty, a hesitation caused by different emotions, forgetfulness, one's wish to think over what to say next is called a h e sit a t ion pause. It is a mere stop of phonation, or it may be filled with so-calleq temporizers (hesitation fillers) such as: you see, you know, I mean; 1 mean to say; so to speak, Well. etc. Very common hesitation fillers are also; um-ah-eh-erm-er,
eg:
You can find him. I think, in the library. What a shame-poor darling; look here. I'll-er-see if I can
buy another pair for you.
There are only two affricates in English: [1[, <6]. In Russian we
have ['I', ]. They are occlusive-constrictives because a complete
obstruction to the stream of air is formed and it is released slow-
ly, with friction. [1[, <6] are bicentral. They have two narrowings,
both flat, the second focus being between the front part of the
tongue and the hard palate (front secondary focus).
Place of Articulation. [if. <tl are palato-alveolar, forelingual
apical.
Force of Articulation. [tf} is strong (fortis), l<tl is weak (lenis).
Voicing. [<t) is fully voiced in word initial position before a
vowel or in intervocalic position, eg Jack, pigeon. In word final
position it is partly devoiced l<t], eg George. 111] is voiceless in
all positions.
Length of Preceding Vowels. Vowels before [tf} are shorter
than before (<tl, eg pitch - ridge.
Palatalization. Since (if, <tl are palato-alveolar. they are
slightly palatalized, because the front part of the tongue is raised
towards the hard palate. but before front and mixed, close or
midopen vowels they are clearer than before back ones. cf
chance - cheese; just - gist.
lif, <tl occur in word initial, medial, final positions,
IUl - spelt "ch, teh. ture, tion", eg chair, question. nature, watch
[<t)- spelt "j, g, dg, gg, dj, de, di, ch", eg jam, gem, margin.
adjacent. soldier, edge, age, Norwich
Definition. Itf, ct>] ar occlusive-constrictive, forelingual, api-
I ,II, palato-alveolar. bicentral; [tf] is strong and voiceless, [ct» is
wpak and voiced. In word final position it is partially devoiced.
Articulation. 1. The tip of the tongue touches the back part
uf the teeth ridge.
2. The front part of the tongue is raised
'Constrictive fricative consonants comprise four pairs [f, v, θ]
They are constrictive because the air passage is constricted
and an incomplete obstruction is formed; they are fricative, be-
cause the air passes through the narrowing with audible friction.
All the fricatives except Lf, 31 are unicentral. Lf, 31 are bicentral,
because they have two places of articulation or two foci, the sec-
ond being produced, by the front part of the tongue raised to-
wards the hard palate thus forming a front secondary focus.
In the production of fricative consonants the narrowing at the
place of articulation is flat. Only when [5, zl are produced it is
round.
Place of Articulation. If, v) are labio-dental, produced with
the lower lip against the edge of the upper teeth; [e. ()) are fore-
lingual, apical, interdental, articulated with the tip of the tongue
projected between the upper and the lower teeth; [s, z; f. 3) are
forelingual, apical alveolar, produced with the tip of the tongue
against the teeth ridge; [h) is glottal, made in the glottis. '
Force of Articulation. [f, e. s, f, h) are strong (fortis); (v,.
z.3) are weak. (lenis).
Voicing. [v, 0, Z,3) are fully voiced in word initial position
before a vowel as in veal. these, zone, giraffe, or in an inteIVocalic
position as in cover, father, bosom.
In word final position they are partly devoiced as in love
[Lw), with [WIO), rose [).
If, e, s, J. h} are voiceless, the vocal cords are apart and do
not vibrate.
Positiot1 of the Soft Palate. Fricative consonants are oral,
the soft palate is raised and the air escapes through the mouth.
Length of Preceding Vowels. Vowels before voiced
fricatives are longer than before voiceless ones, eg leave -
leaf; his - hiss.
PalataJization. English fricatives (except [J,3)) are nonpalatal-
ized, only before front close and mid-open vowels they are a bit
clearer than before back ones. cf father - feet, heart - heat,
thunder - theme.
If Russian learners of English palatalize the fricatives hey
must raise the front part of the tongue only when they pro-
nounce the vowels (front high or mid-open) but not during the
production
