16. The syllable as a prosodic unit. Word stress, its nature and functions. Linguistically relevant types of word stress

The SYLLABLE is widely recognized to be the smallest prosodic unit. It has no meaning of its own, but it is significant for constituting hierarchically higher prosodic units. Prosodic features of the syllable (tone, stress, duration) depend on its position and function in the rhythmic unit and in the utterance. A rhythmic unit is either 1 stressed syllable or a stressed syllable with a number of unstressed ones grouped around it. The stressed syllable is the nucleus of the rhythmic unit. There are as many rhythmic units in an utterance as there are stressed syllables in it. The unstressed syllables are called CLITICS. Those preceding the stressed syllable - PROCLITICS, those following it - ENCLITICS.

WORD-STRESS can be defined as the singling out 1 or more syllables in a word which is accomplished by the change of the force of utterance, pitch of voice, qualitative and quantitative characteristics of vowels.

Types of word-stress:

1. TONIC STRESS - refers to the syllable in a word which receives the most stress in an intonation unit.

2. EMPHATIC STRESS - if you decide to emphasize sth, you can change the stress from the principal noun to another content word such as an adjective or an intensifier.

3. CONTRASTIVE STRESS - is used to point out the difference between one object and another; tends to be used with determiners like "this, that, these, those".

4. NEW INFORMATION STRESS - when asked a question, the requested information is stressed more strongly (the rule of theme and rheme).

Degrees of word-stress:

1) primary

2) secondary

3) tertiary

4) weak

Functions of word-stress:

1. CONSTITUTIVE - unites syllables into words

2. DISTINCTIVE - helps to differentiate the meanings of words or their forms

3. IDENTIFICATORY - helps to identify a succession of syllables as a definite accentual pattern of a word.

17. The accentual tendencies in English. Basic word stress patterns in English

Accentual tendencies:

1. RECESSIVE - 1st and 2nd syllables in Germanic languages are usually stressed

2. RETENTIVE - the borrowed word retains its stress

3. RHYTHMICAL - causes the appearance of secondary stress in polysyllabic words

4. SEMANTIC FACTOR - the most important element of the word is stressed

Basic word-stress patterns:

1) 1 syllable - stressed (drink)

2) 2 syllable - 1st stressed (father)

3) 2 syllable - 2nd stressed (today)

4) 3 syllable - 1st stressed (energy)

5) 3 syllable - 2nd stressed (Canadian)

6) 3 syllable - 3rd stressed (employee)

7) 4 syllable - 2nd stressed (psychology)

8) 4 syllable - 3rd stressed (reputation)

18. Speech prosody. Its perceptible qualities and acoustic properties

PROSODY includes constant non-segmental characteristics of speech: variations in the pitch, loudness, tempo and timber of the voice. Prosody is a synonym to INTONATION - a study of principles and means of division of speech and connection of divided parts such as melody, dynamics, tempo and pausation. Prosody is a broader notion than intonation as it deals with various sound sequences (from syllables to texts), while intonation is applied to speech units no longer than syntagmas.

Perceptible qualities of speech prosody:

1. SPEECH MELODY (rising and falling of the basic tone)

2. SENTENCE STRESS (distributing strong and weak stresses in an utterance)

3. TEMPO (relative acceleration and deceleration of speech)

4. RHYTHM (regular occurance of pattern in time)

5. TIMBRE (tone quality, tone colour)

Acoustic properties of speech prosody:

1. FREQUENCY (=pitch) - Hz, cycles/sec

2. INTENSITY (=loudness) - dB

3. DURATION (=length) – msec
