Unfortunately speech recognition often produces results so unusable that it might be harder to clean it up later as you wouldn't be able to tell what you were even trying to say.

... or, for the sake of argument, the same thing by speech recognition:

Unfortunately speech recognition often produces insulin usable and it might be hard to clean up later can be just you and me I want to tell what you're trying to say.

Maybe my voice sucks, or maybe I should robot it up more, but this is about the level I usually get... it's okay if you're doing a quick search on Google maps and don't mind repeating it 3 times but anything more than that and you may as well start typing.

Anecdotal but yes sometimes certainly it sucks -- I find it useful when I'm in a hurry, so I'll use Siri and say "Remind me to buy milk, toothpaste, red wire." Most of the time it works fine. Sometimes it cuts short and creates a reminder "Buy," or completely botches the words. I've been left standing clueless in the aisle as I'm trying to decipher what Siri should've heard. Especially true in my native language, Swedish.

And that's another issue. "Well of course speech recognition works* (mostly, kinda, in quiet environment, and in about 10 major languages). What, you want to speak your language? Go away - it's your own damn fault for not speaking English or Chinese like normal people do!" For most languages, this is a non-problem with a keyboard.

It would maybe help if there was easy way to mark a word for fixing later.
