Exploring the possible effects of visual presentations on synchronicity and lag in simultaneous interpreting

Abstract

This article discusses the possible effects of the use of visual presentations on simultaneous interpreting, using the media interpreting model described in the literature as the basis for the hypothesis that in order to satisfy user expectations, interpreters will increase synchronicity by reducing lag with a view to maintaining the coherence of the oral/audio and visual input. The article presents the preliminary results of a pilot study drawing on real-life professional data designed to test this hypothesis and the feasibility of further research with a broader sample base. Although only tentative, the results of the study run contrary to the initial hypothesis, with lag increasing significantly when visual presentations are used. The discussion focuses on alternative explanations and a new hypothesis to be pursued in future research drawing on a statistically representative data pool.
