For me at least, dictation is actually the more straining mode of speech recognition, as compared to using my command grammars. With dictation, you might say anything, so the computer is given wide leeway in what to recognize, and so you must speak as clearly as possible. With commands (especially a nice simple command grammar), however, what you can say is greatly restricted, which allows you the freedom to speak indistinctly and still be understood by the computer. This can even be magnified by personalized training of the speech recognition model.

When using commands at my computer, I frequently find myself muttering and grunting things that even I think to myself (that is utterly un-understandable), yet the computer understands just fine. Dictating for prolonged periods can be tiring for me, but I can happily code by voice commands all night.
