26. The definition of the syllable. The muscular tension theory of syllable formation.

The definition of the syllable. The muscular tension theory of syllable formation.

Syllables may be defined as the smallest pronounceable units into which sounds tend to group themselves and which in their turn are joined into meaningful language units that are morphemes, words, phrases and sentences. There are several theories of syllable formation and syllable division and none of them is shared by all linguists.

The muscular tension theory (articulatory tension, or energy theory) was put forward by L.V. Shcherba. He explained the phenomenon of syllable formation by muscular tension impulses. The fact that syllables cannot be further subdivided in connected speech proves that in speaking muscular tension impulses follow one another. Each impulse has its strongest point – the peak of prominence and its weakest point – the valley of prominence. Valleys of prominence correspond to points of syllable division. In the center of the syllable there is a syllabic phoneme which is usually a vowel. In pronouncing a syllable the energy of articulation increases within the range of prevocalic consonants and then decreases within the range of postvocalic consonants.

Unfortunately Shcherba has not left any further explanations of his theory of the syllable, with the result that some of its points remain unclear.

This theory has been modified by V.A. Vassiliev who stated that the syllable like any other pronounceable unit can be characterized by three physical parameters: pitch, intensity and length. Within the range of the syllable these parameters vary from minimum on the prevocalic consonants to maximum on the center of the syllable, and then there is another decrease within the postvocalic consonants.

The definition of the syllable. The three types of consonant theory of syllable division.

Syllables may be defined as the smallest pronounceable units into which sounds tend to group themselves and which in their turn are joined into meaningful language units that are morphemes, words, phrases and sentences. There are several theories of syllable formation and syllable division and none of them is shared by all linguists.

The three types of consonants theory was also put forward by Shcherba. To explain the mechanism of syllable division he distinguished between the three types of consonants, such as initially strong, finally strong and geminate, or double. The difference between these types is in the way they are pronounced. In the initially strong consonants the beginning is more energetic, while the end is weaker. In the finally strong consonants the beginning is weak and the end is more energetic. Double consonants are pronounced in such a way that both the beginning and the end are energetic with a weakening of muscular tension in the middle. Acoustically, they give the impression of two consonants. The more energetic part of a consonant is attached to a vowel, so that initially strong consonants occur at the end of a syllable, while finally strong consonants occur at the beginning of a syllable.

Ex. initially strong consonants: it, us, oath, add;

finally strong consonants: may, tea, new;

geminate (double) consonants: penknife, what time, midday.

In English geminate (double) consonants usually occur at the juncture of words or morphemes. Initially strong consonants follow short vowels, while finally strong consonants follow long vowels or diphthongs. Acoustically, finally strong consonants produce the impression of an intimate blend with a vowel which follows.

Ex. finally strong initially strong

not a tall one not at all

a name an aim

The use of a finally strong consonant instead of an initially strong one in similar sound sequences strikes the ear of a native as incorrect.

Since in syllable division the character of the end of a consonant is more important that that of its beginning, it is more convenient to use terms “strong-end” (finally strong) and “weak-end” (finally weak) consonants.
