I heard the "control" word (and other similar words) stress depends on whether it is a noun or a verb. But I can't find any proof to that. Is it really so?
Examples of what you are talking about are: import, export, present, contract, object, refund, increase, decrease. All of them are nouns when the first syllable is stressed and verbs when the stress is on the second syllable. "Control" has only one stress as far as I know.
