From SpeechStudio Incorporated:
Lexicon Lite creates a backup of your Office XP speech-recognition dictionary. You can restore the backup in case of accidental data loss or on another computer. Lexicon Lite works with Office XP or any SAPI 5 compatible speech-recognition program. Don't let those hours spent creating a custom dictionary be lost! Speech recognition won't work if your words aren't in the speech-recognition dictionary.
