Bing -- free app from Microsoft lets you search via speech recognition

I've been looking at the wide range of speech recognition apps for an article I'm working on for the magazine. Bing (free) is one that I haven't yet mentioned. As you likely know, Bing is Microsoft's powerful search engine. Microsoft calls it a “decision engine” that you can use to find information, restaurants and other businesses, images, show times, travel deals, flight information, weather forecasts, and walking or driving directions. Other features include using your device's camera to scan product codes and to input text by pointing it at text strings that you want to search on.
