百度官方发布的关于STACL系统的博客公告里提到STACL系统的重大技术突破：We tackled this challenge using an idea
inspired by human simultaneous interpreters, who routinely anticipate or
predict materials that the speaker is about to cover in a few seconds into the
future. However, different from human interpreters, our model does not predict the
source language words in the speaker’s speech but instead directly predict the
target language words in the translation.
