Handheld voice translation devices are being tested and have:
◦ been found to be unworkable due to "street dialects" that can't be kept and translated.
◦ interchangeable computer chips loaded with more than 1,000 phrases from different languages.
◦ demonstrated violent consequences if the wrong translation comes out of the unit.
◦ only worked if the operator possesses an advance knowledge of the language in use.
