1. It, us, oath, add; 2. May. Tea, new; 3. Penknife, what time? midday meal.

At the beginning of the 50s prof. N.I. Zhinkin of Moscow proclaimed his ‘loudness theory’. It is based upon the series of experiments that were originally ment to determine the nature of Russian word stress and partly sentence stress.

His experiments have led him to the conclusion that syllables are due to a rise and fall in loudness and not to breath puffs or anything else. He asserts, on the basis of his experiments, that ever}' phoneme possesses a specific inherent loudness which manifests itself when sounds are pro­nounced in sequences.

The so-called expiratory (chest pulse or pressure) theory was introduced by R.H. Stetson. This theory is based on the assumption that expiration in speech is a pulsating process and each syl­lable should correspond to a single expiration. So the number of syllables in an utterance is deter­mined by the number of expirations made in the production of the utterance. This theory was strong­ly criticized by Russian and foreign linguists. G.P. Torsuyev, for example, wrote that in a phrase a number of words and consequently a number of syllables can be pronounced with a single expira­tion. This fact makes the validity of the theory doubtful.

1. Phonotactics as a branch of phonology.

Every language has phonemes, and every language has its own common patterns in which phonemes are arranged to form syllables and the syllables are arranged to form larger units. In some languages all syllables consist of one consonant followed by one vowel (CV), so that no word has a cluster of consonants or of vowels; any word has the form CV, or CVCV, or CVCVCV..., depend­ing on how many syllables it has. In English there are never more than two vowels in sequence in a single word (as in neon, poet, cruel, radio), but clusters of two, three, or more consonants are fairly common: prescribe, district,splints, tempts, for example. Still, not just any two, three, or more con- cluster. There are definite limits, or constraints, on co-occurrence. Phonotactics is the part of phonology which studies and describes such constraints. Phonotactics varies from language to language but there are general tendencies across languages.

* When a syllable onset has more than one consonant, the less sonorant sounds tend to be first, fol­lowed by more sonorant sounds.

*When a syllable coda has more than one consonant, the more sonorant sounds tend to be first, fol­lowed by less sonorant sounds.

In other words, the more sonorant sounds tend to be closer to the syllable nucleus, obstruents < [+son] consonants < vowels.

This is called the Sonority Scale or Sonority Sequencing Generalization.

2. Basic rules of syllable division. As A.A. Kalita writes, in English the vowel of the syllable may be preceded by up to three consonants as in stress (CCCVC) and followed by up to four as in texts (CVCCCC); this is the most general statement of the possibilities of phoneme sequences in the English language. English does not exploit all the possible clusters of phonemes in the word and in the syllable. For instance, long vowels and diphthongs do not precede final /q/, sounds /e, æ, d, ʌ / never occur finally. The types of consonant clusters permitted are subject to constraints. It is the feature of English that in initial posi­tion, i.e. before the vowel, there can be any consonant except / ŋ/; the sound /ʒ/ is rare in a word initial position, but it does appear in rather recent borrowings like gigolo, jabot; no consonant com­binations are possible with / θ, z, ʧ, ʤ/; such consonant clusters as /pw, bw, tl, dl, mh, sr, sj, spw, fs, hr, stl/ never occur initially. Clusters of two consonants before the vowel have one of two forms: Isl + C as in stay, swim, sleep, etc. or C + /w, j, r, 1/ as in twin, beauty, creame, plain, etc. J. D. O'­Connor noted that final clusters are more complex in English than initial ones since they express grammatical meanings of plurality, tense, ordinal number, e.g. /-ksts/ as in texts, /-kst/ as in mixed, /-mpst/ as in glimpsed, /-ksθ / as in sixth, / ŋθs/ as in strengths. According to their position in the phonetic structure of a word clusters can be divided into: (1) prevocalic, (2) postvocalic and (3) in­tervocalic.
