Hi all,

I just added two new dictation sources to my original profile, so I now have three sources on one profile. I'm wondering what exactly gets saved when I close DPI – in other words, do changes to my vocabulary in one source change the vocabulary in all three sources?

Also, what about if I were to have extremely poor quality sound in one of them – will that potentially corrupt the quality of recognition with the other sources as well? Specifically, I created a source using the built in microphone on my computer. (I want it just as an emergency backup in case I should be without my real microphone for some reason.) Needless to say, the sound quality isn't great, and I frequently get the notification about excessive noise. So when I go to switch to another source or close Dragon, and it saves before switching or closing, is it saving excessive background noise behind its recognitions in my overall profile, or just in that source? And will that have detrimental effect on my recognition long term?

Thank you,

When you set up different sources, it means that you can use different microphones. Dragon "remembers" the last source that you are using, so the next time you open Dragon, the program assumes that you are using the same microphone as last time.

(However, I'm not sure whether the source is saved automatically, or when you save the profile.)

Changes to the vocabulary that you might make are stored as part of the profile. It doesn't matter which microphone is selected. Dragon does not pay attention to the microphone you are using as it decides which words you have said.

Creating multiple sound sources for the same user profile simply means one profile with 3 sound sources but there is more information saved than you might think. It takes a minute or so because Dragon has to reload your user profile. 


Poor microphone accuracy with one sound source won't hurt Dragon's accuracy unless you save your profile but even then, the damage is typically very minimal.  However, you don't have to tolerate Dragon automatically saving your user profile. Just look up the word “hack” in the Quick Tips at the top of this page for details on making Dragon ask you whether or not you wish to save your user profile when closing, like it should

Dragon creates and maintains individual acoustic information (models) for each particular source, so they don't affect each other. A way of dealing with them is to to use DragonSources.
