Yes, this is done sometimes by performers or by auctioneers. However, speaking this way sounds unnatural and some of the speaker's meaning is lost when there is no stress placed on any of the words. To my ears, hearing English spoken slowly but with the right inflection sounds more correct than the same sentence spoken quickly but in a monotone.

you can improve your english skills if you speak with native language with skipe or in other way...for became more quickly you must only speak more and be more sicure of what you say so the words will come out
