One application,called Lecture Translation,can easily translate a speech from one language into an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme.
Another machine can send translations of a speech to different listeners depending on what languagethey speak. “It is like having a simultaneous translator right next to you but without disturbing the person next to you,”Waibel said
Prefer to read? So- called Translation Glasses transcribe(转录) the translations on a tiny liquid-crystal display(LCD) screen.
Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech.The electrodes could be replaced with wireless chips implanted in a person's face,according to research-ers.
During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he mouthed-without speaking aloud- a few words in Mandarin(普通话) to the audience. A few seconds later,the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”
This particular instrument,when fully developed,might allow anyone to speak in any number of lan-guages or,as Waibel put it,“to switch your mouth to a foreign language”. “The idea behind the universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are becoming more common in the world,”Waibel said.
