1. Narrow and Broad Definitions of Intonation

Phonemes, syllables and words, as lower – level linguistic units, constitute a higher phonetic unit – the utterance. Every concrete utterance, alongside of its phonemic and syllabic structures has a certain intonation.

Most Russian and Uzbek phoneticians define intonation as a complex unity of speech melody, sentence stress, tempo, rhythm and voice timbre, which enables the speaker to express his thoughts, emotions and attitudes towards the contents of the utterance and the hearer. Speech melody, sentence stress, tempo, rhythm and timbre are all components of intonation. These are perceptible qualities of intonation.

Acoustically, intonation is a complex combination of varying fundamental frequency, intensity and duration (see the intonograms).

Speech melody is primarily related with fundamental frequency, tempo – with duration. But there is no one – to – one relation between any of the acoustic parameters and stress, any parameter and rhythm. About the acoustic nature of voice timbre little is known as yet.

On the articulatory, or production, level intonation is a complex phenomenon. In the production of speech melody the subglottal, laryngeal and supraglottal respiratory nucleus regulate the subglottal air – pressure, which makes the vocal cords vibrate. An increase of subglottal pressure raise the pith of the voice, and its decrease lowers the pith.

There is no single mechanism to which the production of stress can be attributed.

Further investigations are necessary to discover the articulatory mechanisms of the components of intonation.

The definition of intonation given above is a broad definition. It reflects the actual interconnection and interaction of melody, sentence stress, rhythm and timbre in speech.

A great number of phoneticians abroad, including Jones, Armstrong and Ward, Pike, Kingdon, Gimson, O’Connor and Arnold define intonation as the variation of the pitch of the voice, thus reducing it to just one component – speech melody. This is a narrow definition of intonation.

Thus Jones writes: “Intonation may be defined as the variations which take place in the pitch of the voice in connected speech, i.e. variations in the pitch of the musical note produced by the vibrations of the vocal cords”.

In spite of the fact that many scholars do not include sentence another. According to Kingdon, tones are combinations of stress and pitch.

Some foreign phoneticians give broader definitions of intonation. thus Hultzen includes the variations of pitch, loudness and duration, Danes – the variations of pitch and intensity, Haugan – a combination of tone, stress, duration and juncture.
2. Intonation and Prosody

Alongside of the term “intonation” the term “prosody” is widely used. “Prosody” and “prosodic” denote non – segmental phenomena, i.e. those which do not enter into the system of segmental phonemes. The British phonetician Crystal defines prosodic features as “vocal effects consituted by variations along the parameters of pitch, loudness, duration and silence”.

Some phoneticians distinguish the prosody of the syllable from the prosody of the word and the prosody of the syllable from the prosody of the word and the prosody of the utterance. Others apply the terms “prosody” and “prosodic” only to the features pertaining to the syllable and phonetic word or rhythmic group (which are regarded as meaningless prosodic units) and oppose prosody to intonation (which is a meaningful phenomenon).

We adhere to the point of view, that prosodic features pertain not only to syllables, words and rhythmic group, but to the intonation group and the utterance as well, since the latter are constituted by these units.

Therefore the notion of prosody is broader than the notion of intonation as it can characterize both the utterance and its smaller units.

Whatever the views on the linguistic nature of prosodic phenomenon, the phonic substance of prosody is regarded by all phoneticians as the modifications of fundamental frequency, intensity and duration. The most complicated and unsolved problems of prosody are 1) the interaction between its acoustic properties, 2) their functioning in speech and 3) their systematization. Jacobson says that prosody is one of the most difficult and controversial problems of modern linguistic studies.
