Not counting your native language, how many languages can you speak? Maybe one, possibly two. The majority of us cannot speak any secondary languages, while others speak many languages. Pope John Paul II can speak 10 languages, and others claim to speak dozens. Even if you can speak 100 languages, that's only a small percentage of the more than 6,000 languages that exist in the world. This diversity in languages can make it difficult when trying to communicate with someone who doesn't speak a language you understand.
If you are familiar with "Star Trek," then you know about the universal language translators that the show's writers created to deal with the communication problem posed by a multitude of different languages. ViA, a wearable computer maker, has developed an Earth-based language translator that will be available later this year to the U.S. military and English-speaking consumers.
In this article, we will look at the device itself and how it turns English into any one of almost a dozen languages.
Universal Translator Hardware
ViA's universal translator device will look just like the company's wearable computer, ViA II. The computer is about the size of two decks of cards. It is divided into two halves, which are held together by a flexible joint. The 1.38 pound (0.63 kg) ViA II is a fully functional PC that can either be strapped to the user's belt or stowed in a jacket pocket. With dimensions of 9.75 inches (24.77 cm) long, 3.13 inches (7.95 cm) wide and 1.25 inches (3.18 cm) thick, the device packs a lot of power into a small package.
The universal translator will be equipped with a 600 megahertz microprocessor and will run on Windows 2000 operating system. ViA II is compatible with a keyboard or voice recognition software. It's this voice interface that has allowed ViA to convert the wearable PC into a wearable translating device. Here's a look at the parts of the wearable device:
- Microphone - either handheld or a headset
- Speaker - built-in to the front of the device
- Hard disk drive - Will likely be a 2.5-inch (6.36 cm) IBM hard drive. Storage size is not yet finalized, but the current ViA II wearable comes with a 6.2 gigabyte hard drive.
- Power controls - located on the top right side of the device
- Battery connector - runs to a battery pack containing a lithium-ion, rechargeable battery
- PC card slot access - two expansion sockets for two Type II PC cards or one Type III PC card
- Universal Serial Bus (USB) port - allows peripheral devices to be plugged in to the ViA device
- AC/DC jack - can be plugged in at home or in the car
- Integrated input/output jack - used for plugging in digital display
- Heat sink - A magnesium alloy runs through the computer to dissipate heat from the system's processor.
ViA has yet to announce the name for the device, but it has said that the automatic translator will be available in the fall of 2001 with a price of between $5,000 and $10,000. So, just how does this wearable device recognize voices, understand what is being said and then translate it into a foreign language?
Languages in a Box
Work on ViA's universal translator began about two years ago as a way to ensure that people of different languages can communicate with each other in life-and-death situations. Robert Palmquist, ViA's vice president of innovative technology, described the tragedy that sparked the development of the ViA translator. A few years ago, several people died in a fire in St. Paul, MN, because firefighters were unable to communicate effectively with the victims. Non-English speaking residents of the building were trying to flee, but misunderstood where the firefighters were telling them to go and walked directly into the fire. It's possible that if the firefighters would have had a translating device, the fatalities could have been avoided.
Currently, the device is only designed for English-speaking users, because ViA believes the target audience for this device is English speakers. Here's how the device will work:
- When the user talks, his or her voice is detected by the device's voice recognition software.
- A customized speech and translation engine will then determine what the person is saying and translate it.
- Five seconds after the English speaker finishes talking, the translated words are projected by the device's speaker to provide near-real-time translation.
- Responses from whoever the user is talking to will then be translated back into English, allowing bidirectional translation.
Initially, the device will be able to translate English into about a dozen languages, including Korean, Serbian, Arabic, Thai, Mandarin Chinese, French, German, Italian, Portuguese and Spanish. Obviously, the device will not be able to translate word-for-word, but it will get across the gist of what the user is saying. The device is very smart. It allows for differences in English accents, such as the difference between accents in Houston and Boston. It also has a dictionary stacking function, which allows users to add jargon and slang to the standard dictionary installed on the device.
The value of such a device was clear to the U.S. Office of Naval Research (ONR), which invested money for ViA to develop the automatic translator. Joel Davis, program director at ONR, said that the device could replace human translators, who are expensive to train and whose skills tend to diminish over time. Davis says that one translating device would be allotted for a group of 12 soldiers in the field, and the device would facilitate basic verbal interaction with native residents.
A body-worn translator would benefit not only the military, but would also be valuable to tourists, airport personnel, phone operators, and border patrol and customs agents. In the future, we may all wear a tiny wearable translator in order to remove one of the biggest barriers to communication across cultures.
