Donna is right that it is possible to hear the terms pronounced on a number of different sites. That's not what I want you to spend your time on though.
In fact, as you get further along in your training you'll find that one doctor will pronounce a term one way and two others will pronounce it totally different ways. It's no big deal, not a concern at all. Consider "abdomen" as an example. You will here "AbDOEman" and "ABduhmen" but you will recognize and be able to transcribe either one.
The dictation you will be transcribing during the course will provide you with all you need. Just continue following the course as it is designed. You'll find that all the problems you thought you had at the beginning of the course will disappear. You won't even remember them. Don't get distracted with these minor issues right now. Stick with the main plan. It will work for you as it has for thousands of Andrews graduates since 1989. :)
