The word "Siri" doesn't belong in the title or the article, unless a Trabant advertisement has the right to mention Mercedes-Benz in its promotional text. The project does a primitive kind of voice recognition, but it doesn't use Siri.

On this topic, I invite people to try out my non-prototype, non-project toy that uses Google's support for HTML5 speech recognition. It's pretty funny how wrong things go when you try to say something even a bit out of the ordinary:

If I say, "Now is the time for all good men to come to the aid of their country," an old teletype test sentence, the Google recognizer always nails it. If I say, "I hit an uncharted rock and my boat is being repaired," things go hilariously wrong, and every time differently.
