Difference between student/home and business/gover

I’m interested in voice computer light. Can you please explain the difference between the following 2 versions of voice computer light: student/home edition and business/professional/government edition? Thank you

The only difference is the price. The cost of the business/pro edition helps pay for our development costs.

(I do the documentation, scripting, some programming, etc., but need outside help for major projects.)
Also, the extra cost also lets users who can’t afford it, pay whatever they can.

okay I just bought it.
