Speaking rate and information content in English lingua franca oral presentations

Abstract This paper quantifies differences in speaking rates in a first and second language, and examines the effects of slower rates on the speakers’ abilities to convey information. The participants were 14 fluent (CEF B2/C1) English L2 speakers who held the same oral presentation twice, once in English and once in their native Swedish. The temporal variables of mean length of runs and speaking rate in syllables per second were calculated for each language. Speaking rate was found to be 23% slower when using English. The slower rate of speech was found to significantly reduce the information content of the presentations when speaking time was held constant. Implications for teaching as European universities adopt English as a medium of instruction are discussed.
