My preteen boy has grown really fascinated by world flags and he thinks he can beat the world record for that. Problem is, Guinness wants to use https://www.sporcle.com/games/g/worldflags and it's just impossible to type that fast. We tried Nuance Dragon Professional for voice but the recognition rate is nowhere near good enough -- not at all surprisingly, to be fair, I guess it's engineered more towards complete sentences than just single nouns.
What would you use? We have Windows 10 laptops, an iPad, multiple Android phones and tablets. (Even a Windows 7 laptop or two if older is helpful. If Linux is helpful, we can look into that too.)
