you like something to drink (such as juice or soda)? Thus the two basic sentence pitch contours are rising-falling and rising. However, other within-sentence rises and falls result from the placement of prominence on the stressed syllables of certain words. For declaratives or wh-questions with a final decline, the decline is located as a step-down to the syllable after the last prominently stressed syllable, or as a down-glide on the last syllable itself if it is prominently stressed. But for final rising pitch on yes–no questions, the rise always occurs as an upward step to the last stressed syllable, and the high (3) pitch is retained through the rest of the sentence. The ToBI system A more recent approach to the analysis of intonation grew out of the research of Janet Pierrehumbert and developed into the system most widely known by the name of ToBI (short for "Tones and Break Indices"). The approach is sometimes referred to as autosegmental. The most important points of this system are the following: Only two tones, associated with pitch accents, are recognised, these being H (high) and L (low); all other tonal contours are made up of combinations of H, L and some other modifying elements. In addition to the two tones mentioned above, the phonological system includes "break indices" used to mark the boundaries between prosodic elements. Breaks may be of different levels. Tones are linked to stressed syllables: an asterisk is used to indicate a tone that must be aligned with a stressed syllable. In addition, there are phrasal accents which signal the pitch at the end of an intermediate phrase (e.g. H− and L−), and boundary tones at full phrase boundaries (e.g. H% and L%). A full ToBI transcription includes not only the above phonological elements, but also the acoustic signal on which the transcription is based. The ToBI system is intended to be used in computer-based transcription. A simplified example of a ToBI transcription is given below. In this example, two phrases "we looked at the sky" and "and saw the clouds" are combined into one larger intonational phrase; there is a rise on "sky" and a fall on "clouds": L*L*H−H*H* L−L% we looked at the sky and saw the clouds Because of its simplicity compared with previous analyses, the ToBI system has been very influential and has been adapted for describing several other languages.
