The Douglas Adams' classic The Hitchhikers Guide to the Galaxy features an amazing creature called a 'Babel fish' that once placed inside the ear, translates all incoming languages allowing the protagonist Arthur Dent to converse freely with aliens around the galaxy long after the Earth has been destroyed by the Vogons to make way for a hyperspace-bypass. Technology has some way to go before it catches up to Adams' imagination, but PDA based translation devices such as the Phraselator, which provides one-way phrase-based voice-to-voice translation, are now becoming a commercial reality.
The Phraselator works by matching the input phrase with a pre-recorded output phrase that is played through a speaker. The device can be used in this way to provide information, give directions or and ask simple questions in another language.

Using a rugged high-end PDA, the Phraselator is designed to perform in extended temperature ranges, noisy environments, full sunlight or full darkness. While the phrase recognition technology will work on any high end PDA, Phraselator's noise-cancelling microphone and separate background noise level microphone are needed to get recognition up to the optimum level in a high noise environment.
Users can also develop a specific phrase library using the Module Builder and the Phraselator has about five times the power of standard PDAs in its speaker output for phrases that require a little emphasis - 'Stop or I'll shoot" for example.
Initially developed by Marine Acoustics for DARPA (US Department of Defense Advanced Technology Procurements), the Phraselator was used in Afghanistan during 2002 and a new company has been formed - VoxTec - with the goal of expanding commercial applications to include humanitarian assistance, medical, security, travel and law enforcement.
