Bing Services: Local Scout, Music, Vision, Speech
Local Scout
Local Scout, WP7's guide to your current location, is completely integrated into WP7, although it requires location permission and a data connection to operate. When you click on an entry, such as a restaurant, you're provided with details that let you generate turn-by-turn navigation directions and call the business.
Music
Music provides an integrated music identification service that gives you the title, artist, and album of a particular song playing in the vicinity of the phone. This service requires a data connection.
Vision
Vision lets you scan codes and tags, provided that you have a data connection. It's also useful for helping translating text on flat images. Curved, open books don't work well.
The translation quality is similar to that of other automated services, which means that it often contains errors. Translations from European languages are generally of better quality than translations from Asian languages.
Speech
Speech is a simplified voice recognition system capable of calling, texting, searching, and opening applications. It can be accessed from the Vision icon or by holding down the home button. However, there's a slight difference between these two methods. Speech does not work without a data connection when it's used through Vision, but it does when you hold down the home button.
