You're welcome Mike.
BTW. I should add that I've only used the "standard" versions of these programs. So, I would expect (maybe incorrectly) that if you spent the big bucks, you would get more accurate voice recognition. This is probably one of those... you get what you pay for scenarios.
The standard versions (as well as the more pricey versions) do provide for "new" words. Which, I would suspect would be particularly useful for a "non-US" English speaking user.
