US soldiers on peacekeeping duties in the future could find that a portable
translation device will be an essential part of their equipment.
Scientists at Carnegie Mellon University have developed a prototype of a
speech translator that was road-tested by US Army chaplains in Croatia.
"This project shows how a relatively simple speech-to-speech translation
system can be rapidly and successfully constructed using today's tools,"
said the team from Carnegie Mellon University in a research paper published
recently.
The research was commissioned by the US Army, which is increasingly finding
itself in peace-keeping roles where communication is key.
Speaking in tongues
"In the Balkans, the Army is not just supposed to conquer somebody," Robert
Frederking of Carnegie Mellon University told the BBC programme Go Digital.
Translators could be essential for US soldiers
"In a peacekeeping situation, you have two guys trying to beat each other up
and you are holding them apart.
"You can't just shot one of them, you have to figure what is going on and
talk to them," he said.
The portable translator was developed with a year, using commercially
available laptops.
The Army did not want to field-test the device in a battlefield situation.
So instead the translator was tested by US Army chaplains in Croatia.
"The chaplains very often end up having to talk to foreign nationals and
typically don't have any translation support," explained Mr Frederking.
Slow system
For the trials, the chaplains used the translator to speak to Croatians who
knew just a smattering of English.
The system works by having a speech recogniser that picks up the words in
Croatian, turns the speech into text. The written words are then translated
into English and read out by a speech synthesizer.
"It went reasonably well half the time," said Mr Frederking, though it was
slow in translating phrases.
The research team admit that the system is not ready to be deployed in the
field.
But they say their trials showed that a portable translator could be made to
work with further research and development.
The Audio Voice Translation Guide System project was a joint venture between
the US Army, the military manufacturer Lockheed Martin and Carnegie Mellon
University.
