It is generally said that falling intonation is used at the end of a declarative sentence. However, this is not the case with all stretches of spontaneous speech marked in transcription as sentences. In order to consider the relationship between punctuation and tone patterns, this paper examines intonation patterns at the end of sentences in oral presentations, and discusses instances where falling intonation does not occur. The texts used for analysis are eight oral presentations collected at international conferences in the field of physics, and comparison is made with BBC news and lectures compiled in the Lancaster/IBM Spoken English Corpus. Quantitative and qualitative analysis is carried out. Three major factors were found for the non-occurrence of falling intonation at sentence boundaries, and the findings are considered in terms of discourse strategies which affect the production of a text.
11The overall frequency of the occurrence of five tone patterns was used to make the analysis. Frequencies of the nearest neighbouring tone patterns (indicated in { } in the tables) were all excluded.

AbstractThe aim of this paper is to demonstrate the use of the multivariate analysis Quantification of Contingency Tables (QCT) in studying the structure of a corpus on the basis of the distribution of chosen grammatical categories across different text types. Thousands of verbs, nouns and adjectives of the LOB Corpus were dealt with; the frequency lists of these categories across 15 different text genres were processed by QCT. By using the resulting quantities, the relationships among verbs, the relationships among genres and the relationships between the distributions of verbs and of genres in the LOB Corpus were determined. The results were then compared with those later obtained from the distribution of nouns and adjectives. A high degree of similarity in the structures of the corpus was observed, despite the fact that a different part of speech was employed in each case. Stylistic dichotomy between narrative texts and expository texts seemed to play the most important role in determining the structures, thus indicating both the usefulness and versatility of this statistical technique.
