Combined problem triggers in simultaneous interpreting: exploring the effect of delivery rate on processing and rendering numbers

<p>The complexity of simultaneous interpreting may be influenced by so-called problem triggers, i.e. factors that increase the interpreter's processing capacity requirements. These items include numbers, which have been observed by many to affect interpreting. The difficulty of interpreting numerals can increase even more when the source text delivery rate is high. The eye-tracking study presented here investigates the effect of the speaker's delivery rate on number interpreting accuracy and eye behaviour. To this end, we tested professional interpreters (N = 30) and interpreting trainees (N = 24). Our results indicate that a high rate of the source text delivery compromises number interpreting accuracy. In addition, fixation count per minute increases when interpreters interpret at a fast pace. Professional interpreters provide more accurate interpretations, irrespective of the pace of speech, indicating the possible necessity of training interpreting students in dealing with problem triggers, such as numbers.</p>
