34. The definition of word-stress. Functional characteristics of word-stress.

Word-stress is connected with the changes of the force of articulation, pitch, colour and length of a vowel in a stressed syllable.

Like all phonetic phenomena, word-stress can be analized from a functional point of view as it performs three functions, such as constitutive, distinctive and recognitive.

The constitutive function manifests itself in the fact that every word, even a monosyllabic one, has its accent, which gives a finishing touch to creating the phonetic structure of the word as a language unit. Segmental phonemes are joined together into combinations and form syllables which are organized into the word by its accent. So, on the one hand, word-stress constitutes a word, it organizes the syllables of a word into a language unit which has a definite accentual structure, that is a pattern of relationship among the syllables. On the other hand, sound continuum becomes a phrase when it is divided into units organized by word-stress into words.

The distinctive function of word-stress, or rather of its degrees, makes word-stress a separate suprasegmental phonological unit which is called the wors accenteme. The number of word accentemes in a language with free word-stress is determined by the number of the latter’s distinctive degrees, The accentual patterns of words or the degrees of word stress form oppositions. In English there are two word-accentemes: primary and weak, corresponding to primary and weak degrees of word-stress.

Ex. 'import – im'port, 'black-bird – 'black 'bird (the opposition of primary and weak accentemes).

So, the distinctive function of word-stress in English helps to differentiate between parts of speech as well as compound words and word combinations.

The recognitive function of word stress consists in the correct accentuation of words, which facilitates their recognition and comprehension. Word-stress enables a person to identify a succession of syllables as a definite accentual pattern of a certain word. Correct accentuation helps the listener to makes the process of communication easier. If the accentual pattern of words is distorted, the listener’s attention is distracted from the contents of speech to its unusual form, and the normal process of communication is hampered. Misplaced word-stress does not only prevent normal understanding, but also often produces a comic impression.

35. The definition if intonation. Voice tambre and temporal characteristics of intonation.

Intonation - is a complex unity of communicatively relevant variations of non-segmental, or prosodic features of speech which include melody, or the changes of the pitch of the voice, sentence stress, or the greater prominence of some words among other words of the utterance, tamber, or the special colouring of the voice and temporal characteristics.

Tambre expresses various emotions, attitudes and moods of the speaker, such as joy, anger, sadness, indignation, etc. Tambre should not be equated with the voice quality only, which is the permanently present person-identifying background, it is a more general concept, applicable to the inherent resonances of any sound. Tambre is studied along the lines of quality: whisper, breathy, creak, husky, falsetto, resonant, and qualification: laugh, giggle, tremulousness, sob, cry.

Tempo of speech can be normal, slow and fast. The parts of the utterance which are particularly important sound slower. Unimportant parts are commonly pronounced at a greater speed than normal. Each syntagm of the sentence is pronounced at approximately the same period of time, unstressed syllables are pronounced more rapidly: the greater the number of unstressed syllables, the quicker they are pronounced. Proclitics are pronounced faster than enclitics.

Pausation is closely connected with the other components of intonation. Pause is a stop of phonation for a short period of time before starting again. Any stretch of speech can be split into smaller portions, i.e. phonetic wholes (chains of oral speech which is semantically and intonationally complete), phrases, syntagms by means of pauses.

Functionally, there may be distinguished syntactic, or temporal pauses, emphatic, hesitation and breathing pauses. Syntactic pauses serve for segmentation of speech continuum into units and are considered an additional means of unifying and delimiting syntagms or sentences by showing relations between them. They play the semantic and syntactic role.

Syntactic pauses are subdivided into:

  1. short optional pauses which may be used to separate syntagms within a phrase;

  2. longer obligatory pauses which normally manifest the end of the phrase;

  3. very long pauses, which are approximately twice as long as the first type, are used to separate phonetic wholes.

The length of syntactic pauses varies and depends on the degree of semantic importance, completeness and connection of the syntagm with the following one. The more important the syntagm is, the longer the pause after it. The length of pauses is also connected with the rate of speech. It is relative to the tempo and rhythmicality norms of an individual. Sometimes pauses may even disappear in fast speech and the delimiting function is performed by the nuclear tone alone. The length of the “end-of-utterance” pauses is controlled by the person who is about to speak.

Emphatic pauses serve to make especially prominent certain parts the utterance, to attach special importance to the word, which follows it. Hesitation pauses serve as signals of doubt, suspense and are mainly used in spontaneous speech to gain some time to think over what to say next. They may be unfilled and filled, corresponding to silent and voice pauses. The latter have the quality of the central vowels [ə, з:] or [m, з:m].Emphatic and hesitation pauses are made within syntagms as well. They are an additional means of expressing the speaker’s emotions thus performing attitudinal function.
