Temporal Eye-Voice Span as a Dynamic Indicator for Cognitive Effort During Speech Processing: A Comparative Study of Reading Aloud and Sight Translation

This chapter examines the dynamic latency between human translators’ reading input and speaking output during aloud sight translation. It aims to determine whether temporal eye-voice span (EVS) at sentence level could work as a indicator of cognitive effort speech processing. Thirty participants performed both translation tasks with either English or Chinese texts. Their eye movements outputs were recorded by an eye-tracker audio recorder, respectively. EVS sentence-initial sentence-terminal positions in analyzed. The results show that lengths are significantly longer than those tasks. is line total gaze fixation duration count results, which closely related effort.
