Implementing limited voice commands - feasibility and usability

I'm redesigning a software tool for doctors, and am considering including voice commands in the section where doctors need their hands and eyes on the patient, not the keyboard and screen. However, I've never designed for voice commands before, so I'm trying to understand feasibility and usability. Here are some details:
Voice commands would be an alternative, optional way to operate select screens.
On each of these screens there is a limited number of voice commands the user can give (displayed on-screen).
In total, I expect to need no more than a dozen or-so single word commands ("next", "undo", etc) as well as digits ("one two eight point five").
The software is offered to English and German speaking users.
The doctor may be 5 feet or-so away from the computer microphone
The room in which it's used is mostly quiet.
What I'd like to know specifically:
How much training would be required up-front to have the software be able to recognize the user's voice for this limited vocabulary)?
During use, how reliable is recognition?
How big of a development effort is required to integrate 3rd party voice recognition software for this?
Anything I'm overlooking?
Thanks in advance for any help you can offer! Damon
