Simultaneous Translation at Baidu

Real-Time Translation

Liang Huang discusses the advancements in simultaneous translation technology, highlighting its potential to revolutionize communication. Unlike traditional translation methods, simultaneous translation allows for near-instantaneous conversion, significantly reducing communication delays. This innovation is particularly beneficial in scenarios like international conferences, where real-time translation can bridge language barriers effectively 1. Huang emphasizes the ultimate goal of breaking down cultural and linguistic barriers, stating, "It just goes all the way to the extreme of breaking down the barriers between human beings and between cultures, in between languages and between countries." 2

   

Translation Challenges

Simultaneous translation presents unique challenges, both technical and linguistic. Liang Huang explains that the primary difficulty lies in the need for real-time processing, which requires translations to occur almost simultaneously with speech 3. This is complicated by language differences, such as the varied word order in German and English, which can delay translation. Huang shares a common interpreter's challenge: "Whenever a German speaker starts to speak, the interpreter would often pause and do nothing for, like, 10 seconds or more. And when you ask him, like, why you're not translating? And he would say, oh, I'm waiting for the German verb." 4

   

Future Directions

Looking ahead, Liang Huang envisions further advancements in simultaneous translation, particularly in speech-to-speech systems. Current efforts focus on overcoming the limitations of text-to-speech synthesis, aiming for more natural and human-like translations 2. Huang describes the innovative "prefix to prefix" model, which anticipates future words to minimize delays, enhancing the translation experience 5. He notes, "Our technology is not intended to totally replace the human interpreters. We try to reduce their burdens because...there's a huge demand in simultaneous translation." 1
