.NWV File Extension

File generated by Dragon Naturally Speaking (DNS), a speech recognition and dictation program; contains modifications saved by the program's Acoustic Optimizer; includes corrections that improve speech recognition accuracy for a specific user.

The NaturallySpeaking NWV file is named "acarchive.nwv" by default. It will be modified during dictation training if the "Store corrections in archive" box is checked. This option can be found by selecting Tools→Options→Miscellaneous within the program.
