Have you ever had a conversation through machine translation? Many problems arise: “computer bug” may become “computer insect,” and complex ideas like “he asked me to figure this out first when we talked last time” may translate very unpredictably.
In a lab study, we asked a native English speaker and a native Chinese speaker to brainstorm together, some using English as a common language, and others using machine translation.
Machine translation helped the native Chinese speakers produce ideas (Figure 1) but both native and non-native speakers viewed machine-translated messages as less comprehensible than English messages (Figure 2).
This result gives hope for combining machine translation and second language ability to better support inter-lingual communication. It may be effective to use machine translation to help people produce messages in their native languages, while leaving incoming messages untranslated and leveraging people’s second language proficiency for comprehension.
