By now, hands-free, voice-enabled smart assistants like Siri, Cortana, Google Now, and Alexa are no longer alien concept. However, they aren't exactly the easiest people to talk with. One off questions are usually fine, depending on how you phrase them. But carrying on a continuing query is near impossible. That is one area where SoundHound's Hound tries to excel. Now available for public use and with Yelp and Uber integration, Hound promises more a more natural way to ask questions and even refine those questions after they've been answered.
