Raspberry Pi Becomes a Universal Translator

hola-me-nombre-david-conroy

We’re still about 150 years away from the invention of the universal translator by [Lt Cdr Sato] of the Enterprise NX-01, but [Dave] has something that’s almost as good: a speech recognition, translation, and text to speech setup for the Raspberry Pi that theoretically allows anyone to speak in sixty different languages.

After setting up all the Linux audio cruft, [Dave] digs in and starts on converting the guttural vocalizations of a meat speaker into something Google’s speech to text service can understand. From there, it’s off to Google again, this time converting text in one language into the writings of another.

[Dave]‘s end result is a shell script that works reasonably well for something that won’t be invented for another 150 years. The video below shows the script successfully translating English to spanish, but it should work equally well with other languages such as dutch and latin, as well as less popular language such as esperanto and french.

Real Life Subtitle Glasses

[Will Powell] sent in his real-time subtitle glasses project. Inspired by the ever cool Google Project Glass, he decided he would experiment with his own version.

He used two Raspberry Pi’s running Debian squeeze, vuzix glasses, microphones, a tv, ipad, and iphone as the hardware components. The flow of data is kind of strange in this project. The audio first gets picked up by a bluetooth microphone and streamed through a smart device to a server on the network. Once it’s on the server it gets parsed through Microsoft’s translation API. After that the translated message is sent back to a Raspberry Pi where it’s displayed as subtitles on the glasses.

Of course this is far from a universal translation device as seen in Star Trek. The person being translated has to talk clearly into a microphone, and there is a huge layer of complexity. Though, as far as tech demos go it is pretty cool and you can see him playing a game of chess using the system after the break.
