Bing is talking about some new features it has for Windows Phone 7.5 (Mango). This includes voice search, Shazam-like music search, and Google Goggles-like "Bing Vision".
Voice search is pretty self-explanatory. Music search lets you find whatever song is playing by "letting your phone 'listen' to the music. It will then show you the name, artist and album, as well as where to hear or buy it.
The Bing Vision feature is essentially Bing's answer to Google Goggles, which lets you search by taking a picture with your phone. "You can now use your phone’s camera to look up product information by bringing an object into view," the Bing Team explains. "Bing will recognize text and present the option to select words for a search, and instantly return product results if the object has a barcode. Bing Vision can also detect product information from UPC codes, QR Codes and MS Tag as well as cover art for books, CD’s, DVD’s and video games."
There is also a new "local scout" feature, which provides local search results, recommends restaurants /businesses nearby, etc. The results are arranged by highlights, eat/drink, see/do, and shopping (nearby stores).
Finally, there is a feature called "app connect," which lets Bing search results return Windows PHone Marketplace app results when relevant. This is detailed more in the following video:
