I have no policy, for or against: only a personal style. Which is to say, I use them when I think it's appropriate to; for example, an internal monologue by a locquacious and verbose narrator is more likely to be larded with adverbs than an exchange of instant messages between cops at a crime scene.
Speech recognition is utterly crap for writing fiction. If you try reading a novel aloud you'll soon figure out why - written prose style is utterly unlike the spoken word.
For a sampler, you could try my short story collection "Wireless". Which contains one novella that scooped a Locus award, and one that won a Hugo, and covers a range of different styles.
