Academic speech is said to be similar to academic writing. In order to ascertain the validity of this idea, the English used in oral presentations and published papers is analysed in this study with regard to syntax and lexis. Two paper-oral presentation pairs were used for this analysis. In each pair one oral presentation and one published paper with identical titles were produced by a single scientist. The frequency of finite and nonfinite clauses, nominalisations, passives, and conjuncts was calculated. A cluster analysis was made to determine the correlation between the oral presentations and the published papers in the light of the text categories of the LOB and London-Lund corpora. Examples taken from the oral presentations and the papers were contrasted. Lexical verbs were compared. As a result, significant differences have been found between the oral presentations and the published papers in terms of syntax and lexical verbs. The results indicate a shift of preference from finite clauses to nonfinite clauses and nominalisations in the change of mode from speech to writing.
