Two hearts beating in just one mind...

Present.

Como tu pronunciou a palavra acima? /présent/ ou /prisênt/?

And which one is correct?

Well, that depends.

If we're talking about the noun (substantivo) the correct pronunciation is /présent/, but if we mean the verb, surprise, surprise, the correct/prisênt/.

 The same goes for many words such as record (/récord/ and /ricórd/) or export (/éxport/ or /expórt/).
