To no one's surprise, I'll agree with you here ;) I'm just curious
as to whether you know of any actual implementions of this idea.  So
far, all the speech research I've seen has been targeted toward the
sentence and word level, which uses contextual information to
fill-in the gaps.  The raw phonetic translation seems to be quite
lossy and susceptible to sample noise.  It gets worse if the speaker
doesn't talk in their normal tone or changes it halfway, like a
squeaky "Lookout!!" gets translated into 'loo-phiz' since the 'out'
hits the microphone gain.

As humans, we can naturally process out the microphone shuffles,
heavy breathing, etc since we too use context to fill in what might
have been said during the 'phiz'.  I dunno if I'd call it fairly
easy.  But then again, I don't think anyone has actually tried.
