If you need an interpreter for a presentation, start by picking the right type of interpreter for your situation. Simultaneous is one option:
The simultaneous presentation interpreter sits in a soundproof booth while you present without disruption. Audience members who need translation wear earphones. When Nancy Duarte spoke to a large group of business leaders in Taiwan, more than half the audience used earphones. As a result, she got through a lot of material with a lot less time lost. Simultaneous interpretation requires more costs than the other types do, since it involves technology.
