Each user in Dragon NaturallySpeaking has a set of files which represents all of the information which Dragon NaturallySpeaking has learned about how you speak, and about how you write.  This information is known collectively as speech files and consists of an acoustic file and a set of vocabulary files.  (In the Deluxe Edition, there can be multiple sets of vocabulary files and also your macro file.)

The acoustic file which contains all of the information which Dragon NaturallySpeaking has learned about how you talk, represents a significant investment of time.  Not only does this file contain information which was learned during General Training, but any time you perform a correction using the correction dialog, or trained one or more words using the Train Words Dialog, then that information is also stored in your acoustic file.

The set of vocabulary files contains all of the words which are currently active for your user, as well as any statistical information computed when you ran the Vocabulary Builder program.  In addition, any dictation shorthands which you created are also stored in your vocabulary files.

Because your speech files represent such an investment in time, it is important to protect these as valuable data.  Nobody likes having to train Dragon NaturallySpeaking all over again whether system crashes, or when they have to reinstall.  This section will explain where your speech files are located, and give you instructions on how to move them around.

In the Personal Edition version 1.0, your speech files are stored in the following directory: c:\NatSpeak\Users\Customer\current.  This directory contains one file which contains your acoustic information called dd10user.usr and five files which contain your vocabulary information called dd10voc1.voc, dd10voc2.voc, dd10voc3.voc, dd10voc4.voc, and general.voc.

These file locations are shown in the following image taken from the Windows Explorer.
 
 
In version 2.0 of Dragon NaturallySpeaking, the directory structure is slightly different.  The current directory actually contains two or more subdirectories.  Your acoustic file is stored in c:\NatSpeak\Users\USERNAME\current\voice and is called dd10user.usr.  Note that "USERNAME" will be an abbreviation of the user name.  Your vocabulary files are stored in c:\NatSpeak\Users\USERNAME\current\GeneralE.  In the Deluxe Edition, it is also possible to have additional topics which are simply different sets a vocabulary files.  In that case, the subdirectory name is formed from the topic name.

These file locations are shown in the following image taken from the Windows Explorer.  This example is from the Deluxe Edition, and there are to topics -- General English (GeneralE) and Speech Recognition (SpeechRe).
 
 
HOW TO BACKUP YOUR SPEECH FILES

Because your speech files represent an investment of time, you should back the mop.  In that you should be backing up all of the critical data on your computer, but this Web site will restrict itself to discussing your speech files.

I recommend that you backup your acoustic files.  You can also backup your vocabulary files, that is optional.

To backup your acoustic files, copy dd10user.usr to a safe place.  This represent your training.  In the unlikely event that your Dragon NaturallySpeaking configuration gets screwed up and you have to recover, you can copy back dd10user.usr so that you do not have to retrain from the beginning.

If you backup your vocabulary files, copy all five files with the extension of "voc".  You must keep all five files together.

HOW TO RESTORE YOUR SPEECH FILES

In this scenario, we will assume that something has happened to your hard disk and you were forced to reinstall Dragon NaturallySpeaking.

Reinstall Dragon NaturallySpeaking from the CD-ROM.  Then, start Dragon NaturallySpeaking.  Dragon NaturallySpeaking will ask you for the name of your user.  Type in the name of the user you want to restore.  (Is not actually require that you use the same user name, but it is convenient.)

Then Dragon NaturallySpeaking will ask you to run the Audio Setup Wizard, and then General Training.  Click cancel on the Audio Setup Wizard, and then click cancel when General Training starts.  Dragon NaturallySpeaking will then shutdown.

It is necessary to start Dragon NaturallySpeaking so that Dragon NaturallySpeaking will create the appropriate directory structure on disk for your user.  But it is not necessary to run General Training since you will be using the already trained speech files which you saved.

Once Dragon NaturallySpeaking has terminated, copy the file dd10user.usr which is stored in a safe place back to its normal location (i.e. c:\NatSpeak\Users\USERNAME\voice).

If you also save your set a vocabulary files, you can copy them back as well.  You are not required to backup your vocabulary files and I usually do not since they can easily be re-created by running the Vocabulary Builder.

Assuming that you have done everything right, when you start Dragon NaturallySpeaking again it will ask you to run the Audio Setup Wizard, but it will not ask you to run General Training.  You should complete the Audio Setup Wizard to set the volume properly but then you should be able to use Dragon NaturallySpeaking as before.

HOW TO SHARE SPEECH FILES BETWEEN SYSTEMS

You can follow a similar procedure to share your speech files between two systems.  For example, if you have trained Dragon NaturallySpeaking on your computer at work, and you want to copy your speech files to home where you have another copy of Dragon NaturallySpeaking, then you can take the file dd10user.usr home.  And follow the previously describe procedure to restore your speech files (by running Dragon NaturallySpeaking once and canceling before training), except that you will restore the speech file which you took home your other system.

That said, I recommend training again if your computer system at home has a different sound card then your system at work.
