ISpSerializeState

New in SAPI 5.3

Enables applications to to save and restore the recognizer's internal state.

The ISpSerializeState interface allows an application to get the recognizer's internal state, which can then be stored and fed back into the recognizer at a later stage. The state includes adaptation to noise levels and voice characteristics. This is useful, for example, when recognizing discrete recorded files that are known to all come from the same session.
