Siri is being hounded by competitors. One of these competitors is actually called Hound. This video of their Personal Assistant (in Beta still) is sort of mind blowing.
From their website:
Hound gives you fast and deep results to what you ask for, such as looking up the weather, placing a phone call, sending a text message, finding a hotel that matches your detailed criteria, navigating to an address, checking the stock market, searching and playing music, and even playing interactive games.
Hound takes speed and accuracy to a whole new level by combining Speech Recognition and Language Understanding. Just recognizing words isn’t good enough, so Hound does language understanding at the same time. This Speech-to-Meaning capability makes Hound the new way to search and do things faster without typing.
Hound understands both context and details. You can follow up to refine your results, or you can say precisely what you want all at once.
Of course, the cynical side of me wonders why this kind of information is needed at lightning speed. But for now I am just going to hold off on that rant and just admit this is pretty cool.
