Labial, lingual, glottal consonants

According to the position of the active organ of speech against the point of articulation (the
place of obstruction) consonants are classified into: 1) labial, 2) lingual, 3) glottal.

Labial consonants are subdivided into: a) bilabial and b) labio-dental. Bilabial consonants are produced with both lips. They are the /p, b, m, w/. Labio-dental consonants are articulated with the lower lip against the edge of the upper teeth. They are /f, v/.

Lingual consonants are subdivided into: a) forelingual, b) mediolingual and c) backlingual.

Forelingual consonants are articulated with the tip or the blade of the tongue. According to the position of the tip of the tongue they may be: apical articulated by the tip of the tongue against either the upper teeth or the alveolar ridge /t, d, s, z, n, l/ and cacuminal /r/. According to the place of obstruction forelingual consonants may be: (1) interdental / /, (2) alveolar / t, d, s, n, l /, (3) post-alveolar / r /, (4) palato-alveolar / /

Mediolingual consonants are produced with the front part of the tongue. They are always palatal. Palatal consonants are articulated with the front part of the tongue raised high to the hard palate /j/.

Backlingual consonants are also called velar, they are produced with the back part of the tongue raised towards the soft palate “velum” /k, g, /

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

12.modifications of consonants
Ph mod-ns take place w/in the words which are connected and at their boundaries. All the sounds are prone to change.
Assimilation is the adaptive modification of a consonant by a neighbouring consonant in the speech chain.
Can be:
progressive (a sound is influenced by a preceding sound) ex. Bridge – score
[dζ]→[s]→[ς]
lenis – fortis – fortis
lingular
forelingual
apical
palate-alveolar – alveolar – palate-alveolar
occlusive-constrictive – constr – const noise-noise
bicentral – unicentral – bicentral
oral
regressive (anticipatory) the sound is influenced by the following sound
ten balloons [m]←[n] [b], because [b] is bilabial
Good night – both alveolar, but [d] disappears, because of [n] → g’ night
partial – only one or several distinctive features are modified and sounds become similar (bridge score)
complete – the sound becomes absolutely similar to the influencing sound in all distinctive features (good night)
coalescence – a mutual influence, where two sounds fuse into a sg new onewon’t she? [w∂Ụtςi]
alveolar, occlusive, plosive [t] and palate-alveolar, constrictive [ς] →[tς] – palate-alveolar, a new sound – affricate (occlusive-constr), partial ass-n
Practically in all cases – the change of the place of articulation
Then the manner of articulation:
-loss of plosion (glad to see u);
-nasal (not now)
-lateral (table, at last)
Accommodation is the adaptive modification of V+C or C+V type.
Affects lip position →labialization of consonants: appears under the influence of the neighbouring back vowels: pool, woman
It’s also possible to speak ab the spread lip position of consonants followed or preceded by front vowels [i] – meet and [i:] – team, meat
Such sounds as [r], [tς], [dζ] are pronounced by most speakers w/ rounded lips ever after [i:].
In the casual discourse: in the intervocalic position voiceless cons-ts change their voicing value and become voiced: [t] → [d] (letter)
Elision (zero reduction) is the loss of sounds. Min – in slow, careful speech; max – in rapid, careless speech
loss of [h] is widespread
here he is ['iәr i iz]
[l] tend to be lost when preceded by [ō] – always [‘ﺭ:wiz]
Alveolar plosives ([t], [d]) are always elided in case the cluster is followed by another consonant:
next day [‘neks ‘dei], just one [‘dζ^s ‘w^n]
there also exist the so-called historical elision
initial cons-s in “wright”, “know”,”knife”
the medial cons-t [t] “fasten”, ‘listen”, “castle”
the ways the sounds are elided in general:
whole syllables – library [‘laibri:]
some words are esp prone to elision:
“of” + cons-t: a cup of tea [k^pә’ti:], going to [gon^], want to [won^]
Liaison – the process of introducing sounds b/w syllables or words to help pronounce them in a more smooth way:
“linking” r: clear [kliә] – clearer [‘kliәrә], teacher of English
“intrusive” r – sometimes appear b/w the vowels. It’s not wanted here, doesn’t exist, but appears in speech to help pronounce more smooth: Ex. the idea [r] of it
When the word-final vowel is a diphthong which glides to [i]: [ai], [ei] the palatal sonorant [j] tends to be inserted: saying [‘sai(j)iη]
In case of the u-gliding diph-s: [ou], [au] the bilabial sonorant [w] is smtimes inserted: Ex. do it

All these phenomena manifest the economy of pronouncing effort on the part of the speaker.
