Super segmental phonetics deals with the intonation and word stress. Intonation is a complex unity of communicatively relevant variations in voice pitch, stress, tempo (duration, pauses, and rhythm) and timbre. One of the important elements of intonation is the pitch. On the acoustic level pitch correlates with the fundamental frequency of the vocal cords. We may consider voice pitch from Auticulatory point of view—voice pitch is the result of the work of the vibrator mechanism, producing vibrations. Acoustically—voice pitch is complex periodic vibrations combined with main tone. Stress component

a) Articulatory - stress is inseparably connected with prominence of the words in an utterance – result of the work of the power mechanism

b) Acoustically – it is intensity of the air stream

9. Tempo - The temporal component of intonation as rate of speech acoustically manifests itself in duration. Tempo of speech is the relative speed or slowness of utterance which is measured by the rate of syllable succession and the number and duration of pauses in a sentence. tempo doesn't depend on articulation. Functional types of Tempo: normal (moderato), lento, allegro – to differentiate new information –rheme from the given one- theme.

11. Timbre - The timbre component (or voice quality) may be understood as specially changed voice qualities, which help identify speaker's attitude. timbre means special voice qualities, and special articulatory apects aren't singled out
