Microsoft is now offering Microsoft Recite, a search technology for voice that runs on Windows Mobile devices. With Microsoft Recite, the human voice can store, search and retrieve information. Microsoft Recite is available as a free technology preview beginning February 16, 2009.

Microsoft Recite uses voice pattern matching. It analyzes the patterns in speech and finds matches between two recordings -- the notes stored on the phone, and voice search. Recite can store thousands of spoken notes which can be retrieved by matching search term(s).

This is different from speech recognition, which has to accurately convert spoken words to application-readable input.
