I didn't bother with Voice Fields when I started with Dragon Medical 10, but I now think they're a huge timesaver and substantially improve "canned" sounding templates.
Voice Fields are text areas within a template, that are coded in a way that allows you to "jump" to each text field by saying "next field" (or a tab key if you prefer), and then dictating a word or phrase.
For example, I am preparing to dictate an exam. I say the phrase "Dragon-brief-exam", which is the phrase I've trained Dragon to recognize, and the following text appears (shortened for this example):
GENERAL: Appears [0] than stated age.
SKIN: [1]
etc.
If I say "next field" the cursor jumps to [0], and whatever I dictate (older, young or just a space) appears, replacing the [0]. Then "next field" takes me to [1], and I can dictate either an exam or insert a skin exam template by saying "Dragon-skin-exam" (or whatever phrase I have trained).
I have used several of the medical "normal exam" templates already provided in Dragon Medical 10.1. Then I have added "Variable Fields" in these templates to allow me to customize text within the templates.
There is a demo of the process
