If doing magic for more time makes one stronger (which seems to be a hypothesis taken seriously in HPMR), then it is possible that as one gets more powerful, the increased power can compensate for the incorrect pronunciation. In fact, this also may explain to some extent how less powerful witches and wizards can’t cast some spells. In some cases it may be that the orally transmitted version of the spell is not quite right, but that doesn’t matter as much for the more powerful spellcasters. A problem with this hypothesis is that one would then expect there to be weak spells which could only be cast by powerful mages and we haven’t seen any indication of that.
Point against: Professor Whatsisname, the presumably quite-powerful dueling legend, learned/developed “Stuporfy”, which is intentionally meant to sound almost exactly like “Stupify”. If powerful wizards get a pass on their pronunciation, how is it that a powerful wizard can effectively differentiate those two similar spells when casting?

Yes, that undermines the suggestion considerably.
