28. Classification of syllables

According to syllable division:

(Vassilyev)

- open (CV): me, no;

- closed (VC): it, on, end.

(Sokolova, Arakin)

- fully open (V): are, or;

- fully closed (CVC): rat, trap;

- covered at the beginning (CV): so, dry;

- covered at the end (VC): old, act.

According to the length:

- short - one mora (book);

- long - two moras (foot).

According to the change of pitch:

- even pitch;

- changes of pitch (fall-rise, rise-fall).

According to the force of utterance:

- stressed;

- unstressed.

29. Theories of the syllable

1. Expiratory T. (chest-pulse, pressure) by R.H. Stetson.

Each syllable = single expiration. Each vowel sound is pronounced with a fresh expiration. The syllabic boundary is at the point where a fresh expiratory pulse begins.

2. Sonority T. (prominence) by Otto Jespersen, R.I. Avanesov.

Sonority - an acoustic property of speech sounds which determines this or that degree of their perceptibility (vowels, semi-vowels, frictionless continuants, voiced fricatives, voiced stops, voiceless fricatives, voiceless stops). A syllable contains one "peak" of sonority separated from other peaks by "valleys" of lower sonority.

The sonority theory can only explain why this sequence consists of two syllables, but it cannot explain by what means and at what points it is divided into syllables in two different ways.

3. T. of muscular tension by L.V. Shcherba, A.V. Vasilyev.

Sounds in connected speech are pronounced with alternative intensification and slackening of muscular tension. Each peak of intensification with the following slackening of tension forms a syllable. Sounds that are pronounced with intensification of muscular tension are termed pitch sounds. The syllable is an arc of articulatory tension. The pitch sound is the center of the syllable and of the arc of tension (vowel or sonorant).

4. Loudness T. by N.I. Zhinkin.

The syllable is an arc of articulatory effort. The arc of loudness of perception level is formed due to variations of the volume of the pharyngeal passage, which is modified by contractions of its walls. The narrowing of the passage and the increase in muscular tension reinforce the actual loudness of a vowel, forming the peak of the syllable.

30. Rules of syllable division

According to phonological principles: C, representing the point of syllable division, should be added to the next V (re-gu-lar, bo-dy, fa-mi-ly).

According to morphological principles: prefixal and suffixal morphemes are divided from the root one (ir-regul-ar, re-fresh-ment).

According to phonetic principles:

- point of syllable division after stressed long monophthongs, dipthongs and diphthongoids (carpet['kɑː.pɪt], greeting ['griː.tɪŋ]);

- when a short stressed V followed by one C - after or inside the intervocalic C;

- when a short stressed V is followed by a C-cluster - anywhere (['ek.strə], ['eks.trə], ['ekst.rə]);

- when the unstressed short V is separated from a succeeding stressed one by a single C

(before [bɪ.'fɔː], idea [aɪ.'dɪə]);

- when V is separated by a cluster of two Cs (if possible in initial position - before the cluster [ə.'brɔːd], if not - inside [əd.'mɪt]),

- post-tonic - no practical importance.
