Several new features set to be introduced in Microsoft’s upcoming “Mango” update for Windows Phone were revealed this past weekend. We already knew that Mango is set to be a major update to the Windows Phone platform — perhaps the most anticipated new feature is improved multitasking support — but Microsoft had been keeping several upcoming additions under wraps. Newly revealed features include Bing Audio, which will identify songs by listening to music, a la Shazam; Bing Vision, which will provide barcode scanning along with a host of camera-assisted search functions; the addition of turn-by-turn navigation to Bing Maps; speech recognition support in the messaging app; and a new native podcast player. None of these new features have been confirmed by Microsoft at this point but considering the proven track record of the source, it looks like Microsoft’s Windows Phone 7.5 update is going to be even more exciting than we thought.
