pronounced exactly the same way they have a  different spelling and a different meaning.

Sighs means to emit a long audible breath and 

Size means a dimension or a  magnitude, how big something is

So to say these words correctly we're  going to start with that s sound:  

tip of the tongue is either down or behind  the top front teeth. It's not touching.  

Air continues to move out of your mouth.

Next move to the I to do this, you're going to  

open your mouth wide, tip of  the tongue is going to be low,  

back is pulled up. As you close your mouth your  tongue will be high and flat in your mouth: I.

Then end with the z sound z. Your tongue is  in about the same spot, as high and flat,  

the tip of the tongue might be pointing  down a bit. Again you are not touching  

your teeth. Voice box is on and moving. And  you are going to end with that zzzzz sound.

Put it all together S- I - Z 

size size size sighs sighs sighs

And now for a sentence:

The sighs were audible due  to the size of the audience.
