Let's try such words as follows:
DEM-ocrat, de-MOC-ray, demo-CRAT-ic; PHO-tograph, ho-TOG-raphy, photo-GRAPH-ic.
In the following sentences, stress on the different words expresses the different feelings or different ideas:
COME to me. Come to ME. / WHY, George? Why, GEORGE! / HOW are you? How ARE you? How are YOU? / I want some coffee. I WANT some coffee. I want some COFFEE. / GIVE me that book! Give ME that book! Give me THAT book! Give me that BOOK!
To improve your voice, you will stress the word in your sentences which is most important.
Try some of these, stressing the capitalized word.
IT was so pretty. It was SO pretty. It was so PRETTY.
