While phasing issues should be quite apparent on "stereo" audio that has anything mixed toward the middle, audio cancellations will become dramatically obvious if the speakers are placed about foot apart with each facing the other.

I once received a CD that had the channels reverse phased; the producers were glad to get my report so that they could correct the matter before releasing anymore recordings.

FWIW, the exception to this case is if the mixing engineer has intentionally built a sound stage where the performers/singers/actors etc. have been panned to be in different places acoustically. It's not usually done with a single vocalist, but for something like a round-table multi-party interview it makes some sense. Likewise the technique might be found in some music recordings with backup singers, etc.

In such cases, an audio vector scope (as John Stortz mentions) may show an unbalanced off-axis line with mono speech, and it would shift around as different speakers are heard (though it would be tougher to see with stereo audio effects as typically heard during musical selections).

There's definitely an art to soundscaping and mixing audio. Too much, and it's unnatural and distracting; none makes it just as uninteresting (and therefore non-distracting) as the last spoken selection before it.
