This question already has an answer here:
I'm attending a university course on spatial reasoning in computational systems. So the word spatial is often spoken here. The Germans in the course usually speak English slowly and more carefully so that I can hear an obvious difference between the two words spatial and special. But the English native speakers here, who talk a lot faster, don't seem to make a difference between the words.
Am I just unable to hear the difference because I'm not used to it or do they really make no difference?
