end on intonation for their spoken identity, and several specific contrasts, such as question/statement, make systematic use of it.function helps draw attention to what meaning is given and what is new in an utterance. The word carrying the most prominent tone in a contour signals the part of an utterance that the speaker is treating as new information.function helps larger units of meaning than the sentence to contrast and cohere. In radio news-reading, paragraphs of information can be shaped through the use of pitch. In sports commentary, changes in prosody reflect the progress of the action.function helps us to organize speech into units that are easier to perceive and memorize. Most people would find a sequence of numbers, for example, difficult to recall. The task is made easier by using intonation to chunk the sequence into two units. Indexical function, along with other prosodic features, is an important marker of personal or social identity. Lawyers, preachers, newscasters, sports commentators, army sergeants, and several other occupations are readily identified through their distinctive prosody. [1,45]
1.2 Components of intonation and the structure of English intonation group
us consider the components of intonation.the pitch component we may consider the distinct variations in the direction of pitch, pitch level and pitch range.to R. Kingdon the most important nuclear tones in English are: Low Fall, High Fall, Low Rise, High Rise, and Fall-Rise. (See Appendix 1) meanings of the nuclear tones are difficult to specify in general terms. Roughly speaking the falling tone of any level and range expresses certainty, completeness, and independence. A rising tone on the contrary expresses uncertainty, incompleteness or dependence. A falling-rising tone may combine the falling tone's meaning of assertion, certainty with the rising tone's meaning of dependence, incompleteness. At the end of a phrase it often conveys a feeling of reservation; that is, it asserts something and at the same time suggests that there is something else to be said. At the beginning or in the middle of a phrase it is a more forceful alternative to the rising tone, expressing the assertion of one point, together with the implication that another point is to follow. The falling-rising tone, as its name suggests, consists of a fall in pitch followed by a rise. If the nucleus is the last syllable of the intonation group the fall and rise both take place on one syllable. In English there is often clear evidence of an intonation-group boundary, but no audible nuclear tone movement preceding. In such a circumstance two courses are open: either one may classify the phenomenon as a further kind of head or one may consider it to be the level nuclear tone. Low Level tone is very characteristic of reading poetry. Mid-Level tone is particularly common in spontaneous speech fun...
